Enthusiastic photographer looking to make next step
Think it depends on how much input you as a photographer wishes to add to the finished image. If you wish to develop a personal style or to try ideas then you will have to go for a DSLR however good a compact you are limited as to how much of the photographers ideas you can get into the shot, the co...

Enthusiastic photographer looking to make next step
I have a G10 and a K100DS, and there are a few areas where dSLR will always outperform any compact. The most important, which is true of every compact with a small sensor, is control of depth of field, and what is in and out of focus. Even with a kit lens, any SLR is going to give much greater ...

D-Range - to use or not to use?
Well, to give the new Silkypix RC a test run and to answer the long standing question I tried to perform a test that is a little bit more exhaustive. I took a test frame with a high dynamic range: I took a lot of shots from +0EV to +3EV (as shown in the viewfinder), manual settings of aperture...

Hi Guys, I am about to cut down a Pentax MG focusing screen to fit my K100D. I could whip out its screen and check with calipers but trying to minimize handling it :) has anyone got the K100D screen dimensions please ? cheers Pete

Good luck! When you do find the size don't forget to report back so we'll know if anyone asks in future :)

Are they the same thickness? Might be important too.

Are they the same thickness? Might be important too. I have read some articles on that other forum (PentaxForums),stating they have the same thickness. There are some guys who use the screens of the MX and MG to adjust for use in the Pentax KxxxD's. Apparently it also solves the exposure problems...

Also there is small metal shim that separates the focus screen from the pentaprism/mirror. I have a k20d, and bought a Katzeye focus screen. The Katzeye was a tiny bit thicker than the original Pentax focus screen. Accurate focus is so easy to detect with the split prism, and it was disconcerting...

Flushed with focusing success I come with good news :) Decided the tweezers needed boots. Looks crude but held on to the wee tab with no marking. Used lens tissue if fingers needed. The k100d screen was easily released with this finely honed tool :D The numbers are in that gift to goo...

I'm not sure if I am waffling here :? but wouldn't it be important to have the split screen (centre part of the focus screen) dead centre in the view finder :?: for it to work properly. If you have ground away one edge it would be off centre. As I said, i'm not sure if it matters but thought I w...

Awesome job, Pete. It looks as if you didn't turn the split-prism by 45 degrees. I think I'd like that. Makes the grinding more interesting as well. :D

I always use my 1" X 30" belt sander to make new screens. Frosted scotch tape is a breeze to draw pencil lines on. http://greyhoundman.blogspot.com/2006_10_01_archive.html Very good DIY, Transit. :)

I wonder, How is your light meter behaving with this screen and using NON A lenses. Any compensation needed, or is exposure spot on ? Martin.

Both my cameras meter fine with any lens, M42, M, and "A".

Thanks, for answering. It confirms my thoughts on that. The exposure problems occurring with the K10D/20D are screen related when using NON A lenses. Martin.
