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...
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.
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.
