Excerpt: Only use this for faster lenses like 2.8 or faster becasue for slower lenses it becomes very dark.Screen is very accurate for manual focus lenses and almost as good as a split image screen. Great for lens whacking/free lensing.
Excerpt: I "always" use autofocus, but wanted to see a more correct depth of field in the viewfinder. I use mostly the 35mm f/1.4, 50mm f/1.4, and 85mm f/1.2. It's great for that... the background is much blurrier in the viewfinder than before. The downside... with my 2.8 zooms, the viewfinder is definitely dimmer than before. Not noticeable if the light is great, but if the light level is dimmer (read: indoors), then it's definitely harder to see what's going on.
Excerpt: I started using my Voigtlander 40 ultron 2 for about two months before I bought this focusing screen. There were a number of shots I missed. It took me longer than I had hoped to find focus, and focus confirmation. After installing the screen that time was cut significantly. It is clearly better to have this than not have this product for manual focus. It makes it easier to focus around the frame, and not rely on the focus points.
Summary: Not hard to fit, makes a huge difference when viewing scenes with a small depth of field. Use it with 35/50/85 primes at wide apertures and the 100L macro and the difference is very noticeable. Really useful upgrade for under [$].
Conclusion: Ger verkligen en skarp sökarbild, men jag tycker att det blir för mörkt redan vid ƒ2.8. På objektiv med ƒ1.4 och ƒ1.2 funkar det toppen.
Med 200/ƒ2.8 i en sporthall med nomal "sporthallsbelysning" börjar det kännas för mörkt för att man ska ha nytta av den ökade skärpan i sökaren.
Undrar också varför de olika skivorna är så dåligt märkta. Har flera gånger tagit fel när jag haft bråttom vilket påverkar ljusmätningen en smula.
