I've got to agree here, the stock screens are useless when used with a lens like the A50/1.2. When I use this lens on the K-x with the stock focus screen I have to shoot and test to confirm focus or else use LV to get any kind of an acceptable result when the lens is used at large apertures. -- Rob Studdert (Digital Image Studio) Tel: +61-418-166-870 UTC +10 Hours Gmail, eBay, Skype, Twitter, Facebook, Picasa: distudio -- 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 found that the stock screens did not work at all well for me for manual focusing, and that the katzeye screens really help. I think that the stock screens are optimized for autofocus. Unfortunately the Pentax autofocus system seems to be optimized for manual focus. Autofocus on the K-x is especially troublesome in this situation because without the light up dots, I can't tell what it's focusing on. That and the fact that in the light I need it, by the time the camera focuses, whatever I wanted to take a picture of is 3 seconds in the past. There is an aspect of the split screen that it allows your eye to focus on what is in the center of the screen, no matter how out of focus it is. > > I think that practice may help.

At ISO 6400, and missing more photos due to subject motion blur than bad focus, I'd end up with photos with depth of field, but so much noise, or motion blur, you wouldn't see anything. Most of the screen is matte anyways, so I can try using that section more anyways. The focus of my interest is rarely dead center anyways. Most of the situations where I shoot the split prism gets me a lot closer than I could with a matte screen. I know this because I'll focus using the matte portion of the screen, and check it with the split prism. Since most of my photography seems to be with fast lenses 77mm or shorter, I rarely have any problem with the dark center syndrome with the split prism. > Also: Relax. It's only photography.

When I first decided to get serious about photography, some forty years ago, a local pro told me to practice focusing on various things in the room while I was watching television. In a dim room, that was good practice. Even today, when I get a new camera, I'll spend some time getting used to the focusing screen. As I said earlier, I prefer a plain matte screen, although I do like the horizontal and vertical lines that Godders mentioned. I'm using the standard screens in my K20 and K7 now. No problem. I realize there are better options, but they're expensive. If I started missing focus, I'd invest in an ultra bright screen, but so far that hasn't been a problem.

The stock screens in the K-x and K10/20D I find nearly useless for manual focusing, it's pure guesswork. I spent the week shooting with a guy who has an A850 (and a load of great glass), it's got a butt ugly prism hump but the finder view is superb compared to anything from Pentax currently (and I do truly hate the P645 family finders). I have a hard drive full of A850 images and I must say give that I was shooting at the same locations I am just a little jealous of his results (technically). -- Rob Studdert (Digital Image Studio) Tel: +61-418-166-870 UTC +10 Hours Gmail, eBay, Skype, Twitter, Facebook, Picasa: distudio -- 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.

Looked at your photos ... My one advice: get closer, frame tighter. :-) > ... I'm curious if other people have this problem when manually focusing, and > what they do to fix it. .. I see I'm not alone in my preference for plain matte fresnel focusing screens. ;-) Microprism and split prism focusing aids are usually distractions in SLR viewfinders, for me. I always changed my focusing screen to a simple, matte fresnel screen (with horizontal/vertical reference lines preferably) when possible. Longer lenses are easier to focus because when wide open the in-focus zone is shallow; short lenses are where focusing aids can help most. With any lens, good crisp contrast when wide open is the biggest aid to manual focusing, regardless of focusing screen, lens speed or focal length. Beyond that, it's a matter of skill through lots of practice. I find today that I still prefer manual focusing over any autofocus system on any SLR camera I've tried, and I've found that when I manual focus my "hit it on the nose rate" is always much better than when I allow the AF system to do its thing. Canon, Nikon, Pentax, Olympus, Panasonic doesn't matter what the brand. Give me a good, contrasty lens and a clean focusing screen: it will do better than most AF systems. The EVF in the G1 is no exception, except that it makes nailing critical manual focus even easier than any of the optical reflex focusing systems I've used. -- Godfrey godfreydigiorgi.posterous.com -- 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, I may have missed this, but do you use "spot" focus? Do you use "S" mode wherein you can hold focus and re-compose?

Please explain how focal length affects it. Do you find the difference between in focus and out of focus too subtle on a wider lens? -- Larry Colen l...@red4est.com sent from i4est -- 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.

Manually focusing on the wrong "sharp edge"?
I was photographing a friend playing in a small club in Capitola the other night. When I reviewed my photos, I found that an awful lot of them were focused on sharp edges in front of the musician: The tip jar, drum kit, microphone etc. I understand how this happens with autofocus. The camera is too stupid to know what to focus on and focuses on the sharp edge. What I don't understand is why this happens on manual focus. *I* should know better. One challenge that I have in low light is actually seeing the line of the split prism to try and line that up on the musician. Especially musicians that tend to move around a lot. As such, I may rely a lot more on the microprism ring, and wonder if I just focus until I see whatever is in that ring come into focus, and not notice that it's not actually the subject that I'm trying to photograph. More a case of my brain saying "something is sharp, press the shutter". I'm curious if other people have this problem when manually focusing, and what they do to fix it.
