Then there were several with the FA77 ltd, and some with my Bowers/samyang 8mm fisheye. -- Hugs and backrubs -- I break Rule 6http://rule6.info/ * * * Help a hearing-impaired person: http://rule6.info/hearing.html -- 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. -- Larry Colen l...@red4est.com http://red4est.com/lrc -- 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.

I tried out the K-5 II last night, also IR and Back Caps
Larry, the Tamron Back Caps are pretty good at covering the Electronic Contacts on the Lens. There was a Seller offering Lens Back Caps that were Weather Proof for some $ 10 or so each. Try Googling. It does cover the electronic contacts as well. A friend of mine has the K-5 IIs with the 18-135 WR Lens. I have the newer Ricoh K-5 with the 18-135 WR. We tried testing the AF speed of both the cameras in daylight, tungsten, fluorescent and colored bulbs - red, blue and green. There was absolutely no difference in bright day light. However in Tungsten the K-5 IIs was just a bit better in acquiring instant focus. In Fluorescent light there was just a wee bit difference with the K-5 IIs doing better - but not dramatic. The colored bulbs were all around 100 watts, hence medium to low in brightness. In Green light both were just as good. But in Blue and Red lights the K-5 IIs was again just a wee bit faster to acquire focus. Note: a) the K-5 would also focus, just that the IIs acquired focus quicker in the blue and red bulbs. b) we did the tests in the comfort of our home, so cannot say these tests were very technical. Conclusion: The K-5 IIs definitely appears to acquire AF faster, with lesser hunting in low light. But the question is, does it justify the extra $$, as no photos were lost because of the AF speed by the K-5 over the K-5 IIs. Regards.

For reasons I cannot tell, I don't care for the tamron back caps. I will have to look for the weather proof caps. Also, thanks for the feedback on the focusing. The camera seems to be working much better. I don't know if it has to do with it being a K-5II, or just that my old body had a tendency to front focus. Switching it to IR, that would actully be an advantage though. A friend of mine has the K-5 IIs with the 18-135 WR Lens. I have the newer Ricoh K-5 with the 18-135 WR.

I tried out the K-5 II last night, also IR and back caps
It is purely subjective, since I didn't have the K-5 side by side, but the autofocus seemed to be noticeably quicker, and I didn't seem to lose any shots due to bad autofocus. I got off work about 10PM, and stopped to see some friends play at JJ's, a local dive bar. The stage lighting wasn't as bright as it often is, judging by the exposure data, and it was heavier in the red yellow than it has been a lot of the time lately. I'm looking forward to having more time to actually *use* the camera. Since today was a work day (we're on a big crunch at the office) I didn't have as much time as I'd like to sort things down, and pick just a few from the facebook set for flickr, but if you're curious this facebook link should be publically accessible: https://www.facebook.com/media/set/?set=a.10151789840694673.1073741842.653299672type=1l=dbf7f71693 The manual focus test from Thursday night seems to be spot on: http://www.flickr.com/photos/ellarsee/sets/72157634372636444/ My old K-5 is at PCR in Sandy Eggo, getting the sensor repaired, and converted to IR. I'll be looking for both IR and visible light blocking filters. At least a 49mm, and probably an 82mm (and a 77-82mm converter). I figure that if I want to shoot pure IR, then I can just use Live View for composing and focusing. Do people have any recommendations for IR pass and IR blocking filters for use on the camera? This stuff looks like what I'll need to make good IR pass filters for my flashes, both studio and speedlight: http://www.eplastics.com/Plexiglass_Acrylic_Sheet_Infrared_Transmitting Even if I get the small 24x48 inch sheet, I expect that I'll have plenty left over, if anyone needs some, let me know, and I'll post when I get it. I'll wait to order until I've got confirmation that my camera can indeed be fixed. Also, a while back I picked up some bargain K-mount back caps. They don't work so well, as they don't fit tightly on the back of the lens. Does anyone have recommendations for where to get good back caps, with the brim that covers the electrical contacts? I like to use the same caps on all of my lenses, manual or auto focus, so I can just move the cap from one lens to the other when I change lenses. -- Larry Colen l...@red4est.com http://red4est.com/lrc -- 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.
