Re: K-3II announcement and new FA Limited primes coming...
Yeah, in the other K-3 II thread, I had mentioned this myself. I suppose they could do something where each of the four sub-exposures gets 1/4 of the total flash power, with the flash firing a total of 4 times for each resolution-enhanced image. For TTL flash, that would probably require a special flash unit with special programming. I suppose a thyristor flash in manual mode, at a low enough power setting, could also keep up with the four sub-exposures. Since this feature is for stationary objects, and not for action, shooting flash in manual mode wouldn't be too much of a drawback for me personally.

Re: K-3II announcement and new FA Limited primes coming...
If I had the new K-3 II, I wouldn't miss the pop-up flash at all. I generally use either hot shoe flashes or monolights when I need flash. Speaking of hot shoes, this new internal GPS unit won't tie up your hot shoe like the older external model does. Using both GPS and a hot shoe flash at the same time should be easy now. Those of you who never shoot outdoors in the wilderness probably don't need the GPS features so much. It should be a big benefit to those wanting to capture stars as point sources instead of trails though. The compass and logging features might also come in handy while hiking through remote areas. I'd definitely make use of the GPS unit for some of my shooting.

Re: K-3II announcement and new FA Limited primes coming...
Since we're only talking about a senor shift of one pixel, would a little subject movement necessarily ruin your shot? I'd think in many cases, the resulting quality wouldn't be that much different than shooting a normal image without the resolution enhancement turned on.

The logic that combines the four original images into a a single multi-channel image is pretty straigntforward; with the exception of the green component, which is the sum (or average) of values from two of the original images, each component value in the merged image is just a copy of the value in one of the four input images (possibly offset by one pixel horizontally and/or vertically).

K-3 II is Officially Announced

I got an email about this today, and you can find the official announcement on the Ricoh Imaging website: http://us.ricoh-imaging.com/dslr/K-3_II Pentax Forums has also written multiple articles about the new camera. I've been interested in the sensor-shifting approach to resolution enhancement for quite awhile now. The way they've implemented it, the final image resolution stays at 24 megapixels, but the quality and accuracy of those 24 megapixels is noticeably enhanced. Sharpness is increased, color accuracy per-pixel is increased, and noise is noticeably reduced. The images are comparable in quality to other cameras that have a higher pixel count in their image sensors. The new camera also has GPS and a compass built into the camera, with logging capability.

Re: K-3 II is Officially Announced
I believe that means the focal plane shutter opens once, and stays open, for all four of the pixel-shifted exposures. The lens diaphragm should likewise stop down appropriately, and stay constant during the four pixel-shifted exposures. Since the same scene is being rapidly photographed four times to get the final enhanced image, and the focal plane shutter only opens once for this process, it makes me wonder if there will be any complications with flash synchronization. I'm wondering if the enhanced resolution feature will only work properly with constant light sources?

Re: Updated K-30 Firmware, then Manual Mode Disappeared!
Thanks, P.J.! That was the problem. Nothing had actually malfunctioned. However, I do think it's confusing for the camera to claim it's in TAv mode in that circumstance. Perhaps in a pure manual mode, one shouldn't be allowed to use Auto-ISO? There are plenty of other modes where you can use it. I think that would be more straightforward.

Yes, once the Auto ISO is turned off, the screen on the rear shows the mode as manual once again.

My lens would agonizingly hunt for extended periods of time and ultimately fail to find focus--except for those few times the AF-assist light came on.

Re: Definition of pinup?
Technically, I don't consider pin-up to be a genre, at least not a strict or narrow one. It's a reference to a printed image application. Namely, a mass-produced printed image that is typically pinned to a wall, without a frame, and often cheaply available. The calendars that auto mechanics hang in their garages are pin-up calendars. So are many posters of celebrities. A Playboy centerfold pulled from the magazine and pinned to a wall would be a pin-up. An 8x10 glossy photo thumbtacked to a wall could be a pin-up. They were originally called pin-ups, because you literally pinned them to the wall, not because of some very narrow definition of their subject content. Look it up in a few dictionaries, and you'll see I'm not alone on this point. When the original classic pin-up images were being created, did they go to the trouble of only using vehicles that were at least 50-years old? No. They were totally free to use contemporary vehicles. If the original classic pin-up images could use contemporary vehicles, why shouldn't you have that same freedom? Was there any sort of official international treaty that decided the use of contemporary vehicles in pin-up images had to cease by a certain year? No. Feel free to use vehicles from any era you like, even futuristic vehicles. I do realize term Pin-Up is commonly used these days as a genre, but I think its application is often a bit misguided. Some folks seem to think there are very narrow and strict guidelines as to what can be Pin-Up and what can't. I think that's poppycock. If it's a genre at all, I think it's a fairly broad one. I also think it needn't be frozen in time. I think there should be plenty of room in this world for modern looking Pin-Up images, and for Pin-Up images that push the envelope and take the category to new territories. Else, there will be very little true art in the genre, and everyone will be endlessly and slavishly copying everyone else. Note: If you use the term in its classic sense, to refer to an image literally pinned to a wall, it's pin-up. If you use the term to refer to an art movement, then it's Pin-Up (capitalized). I have very similar feelings about folks who consider pop music a term that refers to a particular genre of music, when it literally just means music that is popular — any music, any genre, as long as it's popular.

A Few K-30 Questions
I was hoping someone could answer a few questions I have about the Pentax K-30. Some of these are a bit obscure, and aren't things you commonly find mentioned in most online reviews. 1) I know it has live view, but can that live view be displayed on an external monitor of some sort? 2) Is it possible to control the camera's aperture and shutter speed remotely? 3) Is it possible to shoot tethered at all? 4) It's not a deal breaker for me, if the K-30 can't do those first 3 things, but it would be a huge bonus. If the K-30 can't do those things, is there a Pentax DSLR that can? 5) With my old Pentax DSLR, it's extremely difficult for me to achieve critical focus when using manual lenses. (It has no live view, and no focus peeking.) Since the K-30 has live view, with magnification and focus peeking, I would think accurately focusing an older manual lens would be very easy.

K-100D vs K-30 -- Noise at high ISO?
This is going to be a difficult question to answer without showing comparison images, but can anyone give me some sort of idea how noisy a K-30 is, compared to the much older K-100D? One of the things that bugs me the most about the older cameras like the K-100D, is the very noticeable noise at higher ISO's. With every step above ISO 200, I can notice additional noise in the image. I think ISO 3200 is horrible. I've read comments from folks who had much newer DSLR's of various brands, and some of those folks seem content with ISO 3200 on THEIR camera, and I think I've even read a few mentions of folks being satisfied with ISO 6400 for certain applications. So, how good is the K-30 with regards to high ISO noise, and try to compare it to an older model like the K-100D if you can. I'm hoping the K-30 will let me shoot a few stops higher ISO without sacrificing quality. Would that likely be correct?

Which Macro Lens?
Please help me decide on a used Pentax macro lens. I've narrowed it down to these two used lenses: 50 F2.8 SMC MACRO D FA 100 F2.8 SMC D FA MACRO What are the pros and cons of the 50mm vs the 100mm? What applications would the 50mm be best for? What applications would the 100mm be best for? Does either of them have a reputation for being noticeably sharper than the other? Would the 100mm exacerbate the already shallow depth of field inherent in macro photography, in other words, would the 50mm have greater depth of field at 1:1 magnification?

Re: Pentax AF-500FTZ Flash on K100D
I purchased the AF-500FTZ flash. In case anyone was wondering, here's what works with this flash on a Pentax K100D: Manual mode: - Works at all power levels and zoom settings Flash automatically zooms to match the 18-55mm lens: - Works Flash zoom manual override: - Works Focus assist light: - Works Strobe (multiple burst) mode: - Works Ready light in viewfinder: - Works Automatically limits camera shutter speed to 1/180 max when the AF-500FTZ is turned on: - works Optical slave mode: - Works, as long as the master flash doesn't use P-TTL or red eye reduction. Second-curtain sync? - Yes and no. The delayed sync timing works, but the flash always fires at full power. TTL mode: - No, because the K100D doesn't support it. The flash always fires at full power when set to TTL mode, and used on the Pentax K100D.

Pentax AF-500FTZ Flash on K100D
I'm strongly considering purchasing a used Pentax AF-500FTZ, mainly for off-camera strobist style shooting. As I understand it, the unit has a built-in optical slave which should work fine for manual-mode, strobist style shooting. I'd also like to us this flash in the hot shoe of my K100D, which only supports P-TTL mode. I know that I'll have to use the AF-500FTZ in manual mode to control the exposure. I'm fine with that. Do any of these other AF-500FTZ features work with K100D: Focus assist light? Strobe (multiple burst) mode? Second-curtain sync? Ready light in viewfinder?

Re: Pentax GPS accessory
This seems like it would be a good application for blue tooth technology. That is, if only Pentax cameras were built with blue tooth capability.

Re: Which Macro Lens?
I just realized that I have a lens-reversing adapter. I just mounted a Pentax 50mm f2.0 lens on my camera backwards, and it gave fairly impressive results. When shooting coins, a US quarter will almost totally span the narrow dimension of the frame. There is just a very tiny amount of space left on both sides of the coin. Using this same adapter, along with a special adapter plate for my old Omega enlarger, I can mount my Pentax DSLR in place of my enlarger head. This will let me shoot high-magnification macro through my EL-Nikkor enlarging lens. With the camera mounted on the enlarger it's not terribly portable, but I can definitely make use of this here at home. These are some things I can make good use of right now, until I get more elaborate macro gear. :) I want to think everyone for their macro lens suggestions.

Is Live View Also Sent Over The Video Output?
I was wondering if any of the Pentax DSLRs actually transmit a Live View video feed through their video output connection? The reason I'm asking, I'm trying to figure out if it's possible to place a Pentax DSLR in a remote location (on the end of a pole, for example) and view the Live View signal on a remote monitor. If so, you could trip the shutter remotely and use the camera in places where it's physically impractical to place your head behind the camera. If this would work, which models of Pentax support this sort of remote live viewing? -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

Which Macro Lens?
I'm considering spending some money on a new macro lens. I used to have an older Pentax 50mm f2.8 autofocus lens that was built like a tank, and took very sharp photos. I bought it used at a local shop for only about $100, which was a huge bargain! Unfortunately, that lens got stolen along with the camera it was mounted on at the time. God, how I wish the thieves had stolen my inexpensive kit lens instead! :) Anyway, I'm currently shooting with a K100D, and I'm trying to decide between getting one of these new macro lenses: Pentax smc P-D FA 50mm f/2.8 Pentax SMCP-DA 35mm f/2.8 Are either of these lenses noticeably sharper than the other?

Re: finding pictures or making pictures?
Lately, most of my photos are loosely planned. I'll typically know the subject, theme, and location. I'll usually know some other details as well. However, I'll frequently have to improvise a bit, once it's time to start shooting. Sometimes circumstances will force me to revise my plans at the last moment. Other times, unforeseen opportunities will present themselves during shooting. Because of such uncertainties, I don't often try to plan my images in intricate detail. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

Hi Scott, My firmware was only 1.00 before I did the upgrade. That particular revision didn't support 4 gig cards.

My *ist DS was stolen - need new gear
I recently had my Pentax *ist DS stolen, along with my Pentax F 50/2.8 Macro lens, and a 2 Gig SD card. Insurance will cover part of the cost of replacing the gear. For now, I just need to figure out which camera body to replace the DS with. BH Photo only lists the K10D and K100D models. The Pentax web site for the USA lists 4 models. K10D, K100D, K100D Super, and K110. I think I can live without the K110D option, but what about the K100D Super? What does it offer above the basic K100D? Should I look for that model someplace other than BH? Can someone who has used both cameras please tell me what to expect when moving from the DS to the K100 or K100 Super? Are there any disadvantages at all to these, compared to the older DS? Likewise, can someone compare using a DS with using a K10D? Is the PRIME chip really much benefit in this model? Are the extra megapixels really that useful? I'd like to have the K10D, but I'm not sure if I can raise enough money on short notice to get one before an event I'm attending on July 21st. I might have to settle for one of the K100 or K110 variants, assuming I can live with their feature set. thanks, Glen -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
Disadvantage of no A setting on some manual lenses?
Hi, I have a Pentax DS, and I'm thinking of buying a used manual focus 28mm lens for it. I already have a 50mm f2.0 manual focus lens and I like the image quality and fast maximum aperture quite a lot. My 50mm f2.0 lens has an A setting on the aperture ring. I leave the lens set on this, and adjust aperture on the camera body. I like it just fine that way. However, I've noticed that some of the used 28mm lenses I've seen have an A setting on their aperture rings and some don't. What would be the disadvantage, for a DS user, to not having the A setting on the aperture ring? I assume that shutter-priority and program-mode auto exposure would be out of the question. Is there anything else I should know about? Would I have to use stop-down metering with such an lens? thanks, Glen -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net

I don't know if it makes a difference which side of the diffuser the polarizer is on, but you need them to be in aimed the same direction. The polarizer must be in front of the diffuser. The light emitted by your light source travels through the diffuser first, and then through the polarizer.

Re: Crossed polarization techniques
Barry Rice wrote: Hey Folks, Has anyone on this list experimented with cross-polarization flash techniques? Basically, you put a linear polarizing sheet in front of your flash, and a linear polarizing filter in front of your lens. Orient the two filters at 90 degrees to each other. Yes, I've used this technique. You can actually use a circular polarizer on the lens, if you happen to have one already. If you are using continuous lighting instead of flash, this might help your camera with metering more accurately. I've noticed a tiny warming or cooling effect when using the circular polarizer. (Whether it's warmer or cooler, seems to depend on how you rotate the polarizer.) It isn't immediately obvious to most people, and you could probably easily ignore it. It is a rather small effect. Personally, I prefer using linear polarizers in both locations. I just live with the meter being off, and compensate for the exposure. For maximum effect, the only light sources involved should be polarized light sources. If you have some daylight streaming through a window, for example, it can kill most of the effect, because the daylight won't be polarized. One side effect will be the effect of metallic objects sometimes appearing black, or having black highlights, because the cancellation of light was total on the metallic surface. Colors can look very saturated with this technique. It sometimes leads to very unnatural looking results. One final note: If you orient both polarizers the same way, you can actually -enhance- the amount of glare or gloss in a scene. For example, if you were photographing a glazed ham in a product shot, it might make the glazing look glassier. take care, Glen -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
