Same exposure problems with the Katz Eye when stopping down M & K lenses.

m42 adaptor and k20d
I still believe there is a difference between metering with the Green button and metering with the lens manually stopped down. Recently for instance, I found metering was OK with an M lens when using manual extension tubes. And other posters to this forum and DPR have reported that metering is OK...

m42 adaptor and k20d
In what way are new Pentax and Katz Eye focusing screens non linear? What does that mean exactly? I'm not sure about the "non-linear" part but I was led to believe that the problem with the later Pentax screens is that they've had a bright coating (optional on Katz-Eyes) to make them more bearable w...

50mm A 1.7mm
No. You'll get super results from the 50mm once you've got the hang of it. Treat the green hexagon as a rough guide only. You can actually often focus more precisely by judging by eye. Failing that, take several shots with several slight adjustments of focus. If you want to get more seriously in...

50mm A 1.7mm
...If you want to get more seriously into manual focusing I can recommend the Katz Eye split-image focusing screen. Costs as much as some lenses though. Are these available in UK? I can only find them in the States.

Pentax/Sigma 50 f1.4 Comparison
Sometimes you'll find it easier to achieve sharp focus with AF, other times with MF. I can't be more precise than that because it very much depends on the subjects and your skills. I find MF sometimes more accurate than AF when the subject is well lit and shows up clearly through the viewfinder -...

Old Lenses on a New Body
I got my split-prism screen from a chinese seller on ebay. It works perfectly. Some recommend the Katz-eye which is quite a bit more expensive. Fitting is not difficult, a pair of tweezers is all you need. A google search will bring up instructions.

What lenses would be best for portrait work
I don't believe this. The Katzeye screens do not impact on the metering, From the Katzeye website. Metering Information Because of the presence of the prisms, the Katz Eye™ focusing screen for the Pentax K10D/K20D will have some effect on the camera’s light metering. Test results for each of...

Difficulty in focusing with manual focus lenses
The green hexagon doesn't show up when the contrast or light coming from the subject is very low. In that situation, try focusing on a different part of the subject, or just use your own judgement based on how sharp the image looks on the focusing screen. A Katz Eye screen can be worth buying if ...

SMC Pentax A 50mm 1.7 prime lens

Pentax-FA 50mm F1.4 v Pentax-A 50mm F1.7 @F2
Yup! the 1.4 gets my vote!......but could it be down to manual focussing!.....my 1.7 is extremley sharp when I get it spot on......Ken My manual focusing perhaps could have been a touch better, but I did try about 8 times with this subject. Started at infinity, take a shot, move the ring a tiny bi...

Problems using aperture ring
Why do Katz Eye supply different screens for different models? See http://www.katzeyeoptics.com/cat--Pentax-DSLRs--cat_pentax.html "Even though the screens look similar, many will not interchange!"

What "Normal" lens for K-7
Obviously I want an AF lens... Not sure why this should be "obvious" ? I have been using manual focus more and more lately, particularly since I bought axl's Katz Eye split screen, even with autofocus lenses. If you want autofocus then fine, I buy AF lenses too, but I don't see what is "obvious" ab...

landscape lens suggestions please
John, thanks I have the dioptre set OK, done with the lens off and I have a Katz eye split that is crystal sharp and spot on if I focus on a subject, but what I find is the helix on the kit lens is so fine that at the infinity end of the scale there are tiny movements required to get from say 3 me...

K-mount lenses on istDs.... probably stupid question
[quote:1bb16395de="Arthur Dent"]Multi-point autofocus is one of the most amazingly usless inventions in the history of technology. The camera doesn't know what you're trying to focus on! Stick witgh single point focus or manual, you'll save yourslf a lot of grief. ...why would you let something ...

K100D mods (am I nuts?)
Well I don't have any tools and I certainly have no experience. I'm still interested in the focussing screen idea but I'll probably end up just buying one from katz eye unless it turns out to be easy to trim the one from the ME.
