NEW Pentax DA 16-50 Lens Question
Can you show us some of those disappointing images? Unless I am pixel peeping I can hardly see any problems with the 16-45 at the wide end with the aperture wide open. Call me picky........ Carl You're picky. These are 100% crops. You might just possibly spot a tiny bit of CA on the last one ...

NEW Pentax DA 16-50 Lens Question
You can identify faults in any lens if you choose extreme conditions and then view things under a microscope. Taking pictures against strong back-light is sedom going to give you a good result anyway. G I asked you to call me picky and you did. These are not extreme conditions just a spring ev...

Which lenses for K100D?
I was lucky enough to pick up a SMC M 3.5 135mm in mint condition for £5 a few years back. I find it a superb handling lens, mechanically very well made and very compact. I have used it to take many pictures of the kids as they have grown up, the extra focal length I find ideal for more candid port...

Help on lens
I've got/had a couple of Sigmas and been perfectly happy with them. But, one thing to consider that swung me to the DA 12-24 instead of the 10-20 was that the supply of new K-mount stuff generally is currently tight. So if I did finally get one and it was dodgy there was not much chance of getting...

Pentax A 50mm F1.7 and K100D
Hi, I've managed to get hold of a Pentax A 50mm F1.7 lens and if my understanding is correct this will work with full auto focus on my K100D? Do I need to still set the use aperture ring option to enabled to use it properly? Any comments on this lens on a digital camera, I guess with the K1...

Pentax A 50mm F1.7 and K100D
To save you time, let me tell you that it can't. First off, George is right. Well very, very nearly :P On its own, an "A" series 50mm lens (manual focus) cannot magically focus itself - it's missing all the cogs and linkages to do that :roll: But the camera can give you focus confirmatio...

Pentax A 50mm F1.7 and K100D
Thanks for the info guys... in fairness i think it was me that misunderstood what i was being told about the lens rather than being told that it would auto focus... i did wonder how it would auto focus without the mechanics.. but brain didn't kick in.. apologies :oops: Will try harder to engage...

Pentax A 50mm F1.7 and K100D
Hi Craig... I have a K100D and use all Pentax M lenses... the trick, as I was so helpfully told on here, is to set the little lever under the shutter button to open and close the aperture (in custom settings). Put the camera on manual and when you pull the lever round you can set the exposure with t...

Using M42 lens on Pentax K10D
Hi, I am a Canon user but I am thinking about a shift to Pentax side. I own an EOS 400D with some good zoom lens for a year so it would be unfair saying that I am new. I want to buy some M42 fixed focal lens to use with the K10D, but first of all an adaptor is needed. Apparently I want the Pen...

Using M42 lens on Pentax K10D
Adapters are always available on Ebay. However, the correct adapter sits flush with the lens mount. Some unscrupulous vendors sell what they claim is an M42 - K adapter but it has a wide flange which means it sits proud of the mount, and prevents infinity focus. Bad: http://tinyurl.com/2ytcl9 ...

Most Wanted Lens Thread!
Well I hope Mr P is reading this. My 28mm Shift is easily the best lens I own; sharp as a tack even fully wide open, delivers paper cuts at F8 and probably because of the palaver of using it: tripod with spirit levels, grid focussing screen, pre-set aperture, manual focus with DoF scale and filter w...
