*ist-D K Mount Question
Date: Fri, 3 Oct 2003 09:26:14 -0400 Sorry, I should have been more specific. I thought it occurred in AE as well as manual. I will double check this when I get home. What was curious was that I could see the aperture closing if I looked into the lens. As for DOF, I was focusing on something only a few feet a way. The DOF difference between 2.5 and 32 was pretty noticable focusing on the some point with the same lens with an LX.

Bill - Original Message - From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Friday, October 03, 2003 9:12 AM Subject: *ist-D K Mount Question I was playing with an *ist-D and a K lens (the SMC 135 2.5). Shots made wide open seemed to be exposed pretty well. If I set the lens to a smaller aperture, I could see it stop down when the shutter was released. But the exposure and depth of field on the picture appeared to be the same as when the lens was wide open -- that is, as if the picture was not taken at the same time that the lens was stopped down. Has anyone else noticed the same thing? (Or perhaps my judgment of exposure and depth of filed was just plain wrong, but I'd expect to see a pretty obvious difference between shooting at 2.5 and 32).

This is what caused me to think the lens wasn't stopping down during exposure on automatic. It's because it isn't. OTOH, on manual, it seems to work. William Robb
Re: SV: M42 to K mount question
Thanks Jens.I just find it strange that with an A or M lens on the K1000, i can get the meter needle to go from bottom to top when running through all the aperature settings. I put the 200(and the smc 135 f 3.5 )on the K1000 this wekend and the needle will register from the very top to only the center,but not go below as with other A and M etc. There seems to be a lot of 'play'in aperature when the needle gets close to centreie:as 2-4 change in aperature still keeps the needle in or near the centre,wereas in the A or M 1- 1 1/2 stops will move it out. Its sunnyer today,i'll see whats happens Dave Begin Original Message From: Jens Bladt [EMAIL PROTECTED] Sent: Sat, 30 Mar 2002 20:49:14 +0100 To: [EMAIL PROTECTED] Subject: SV: M42 to K mount question Hi Hi Dave I'm quite sure that the meter is normally not affected by the mount used. Provided that the lens/camera works correctly. The movement, as you describe it, is only affected by the way (the speed) the changes of the light, that hits the meter - the changing light at the scene or by the way you turn the dials on the K1000. Are you sure that the aperture simulator is activated properly by the lens/aperture?

Hi Dave Yeah, that's odd! I can't really test it 'cause my daughter has my K1000 right now. But as I see it: To posibilities: 1. The thread adaptor/mount does not work right (aperture simulator) 2. The 200mm/3.5 let's in less light than the A and M/faster lenses? The best test is to take some pictures (slide film are best) with all three lenses. Note down what you are doing. Shoot some with the same aperture (i.e. f1:4, f1:8) on all lenses. Compare the results carefully. I spent a lot of time/money doing systematic tests: It's absolutely worthwhile doing!

M42 to K mount question
Hi all.I tried out my new adaptor yesterday,using a Super Tak 200 f4 on the K1000.One thing i noticed was the light meter was noticably slower moving with the 200 that if the 35-80 or 80-200 was attached. Is this a common thing. Mind you the weather has been really cloudy and windy lately.

Not the be rude, but don't hold your breath. If Pentax doesn't think there is enough of a market to make it fly, then any of the K-mount-compatible off brands won't even give it a go as they are basically trying to steal marketshare from only Pentax anyway. I suppose it is possible someone might try to put such a beast together themselves, but that idea seems to have died a while back when people found out how expensive the CCD chip was ($3500 for the Phillips CCD chip alone, as I recall). I suspect the best bet for the near future will to go with the products that are already out. Unfortunately, I suspect won't include Pentax for several years yet. bummer, patbob ([EMAIL PROTECTED]) - This message is from the Pentax-Discuss Mail List.

K MOUNT question
Are there any current manufacturers licensed to produce K-mount camera? I ask because I am wonder once 24x36cm CCDs become common place, is there a 3rd party (Phoenix) who could put out a body we could buy if the P_Gods haven't shown us the way? - This message is from the Pentax-Discuss Mail List.

Ricoh, Casina, Vivitar, and ??? I guess if there would be a point in history where Pentax wouldn't make any film based cameras anymore, there would have no reason for other manufacturers to do anyway. regards, Alan Chan _ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp - This message is from the Pentax-Discuss Mail List.
