guys i finally did it! I used a dremel! hehe. It was impossible for me to cut with a cutter, how the heck did you do it with a cutter?
The 1st 1, i ruined it. It was the Nikon FA/FE2, I was excited and very inaccurate. Anyway it back-focused. It was about as thin as the stock one, only a little bit thicker imo. Needed the shim.
The 2nd 1 was much better. It was the Nikon F3. NOT perfect at all because the prisim/split is NOT centered properly
. It's a bit top-right position. This one doesnt need the shim, and with an autofocus lens, focuses correctly
I will plan for the 3rd one more properly.
Things I have learned:
- Use the SLOW rpm setting if you're using a dremel.
- Be careful with the focusing screen bracket. Mine got dislodged and it was a pain putting it back!
- Use tweezers that have a "soft" edge.
- Try to be as precise as possible with the measurements. It's bloody annoying for the prism circle not to be at the center of the viewfinder!
The blackout at f8 is also annoying. Perhaps I'll try to find a screen that doesnt have a split screen, BUT can see wider than F2.8
I have no choice but to make a new one and to make it as perfect as possible, because my stock focusing screen is now full of scratches due to getting taken out and in all the time!
