Originally posted by Nesster I like microprisms, this one shimmers beautifully and thus is a good aid as well.
I am with you. The early pentaprism model starting with the '58 "K" have micro-prisms, and from that time on they had increasingly better and better viewfinders.
It is interesting to note that while the H2/S2 (1959) spec states "micro-prism" ** grid **, it is not so much a grid as it is a series of lines at about 45 degrees that end up behaving similarly to a grid, but not exactly like one. I wish I could illustrate it.
By the time they got to the S3/H3 (1961) they had it. Those cameras when stopped down very clearly show it to be a grid of opposing 45 degree lines, the space between the intersections of course forming the microprisms.
My favorite cameras for daily shooters are the later S3/H3 (1961) and the SV/H3v
(1962) precisely because by this time they had rather perfected the whole thing and it is a very sensitive and exacting piece of optics.
For a while I thought my sight was completely failing. As my optometrist loves to tell me, your 40's will not be kind to your eyes. It is true and to some extent they are failing. I was getting a lot of blurry shots with my '57 AP. Well, since all that camera has is a the fresnel without a micro-prism grid, it was no wonder.
Then I picked up my H2, S3, and SV and found that I CAN still focus. I think the S3/H3 SV/H3v were definitely the pinnacle of their focus screens BEFORE the Spotmatic. Indeed, I think I prefer them over my Spotmatic and Spotmatic F because the microprism portion of the focus screen is ** significantly ** larger than on the Spotties.
Hmmm... I wonder if I could swap them out to the Spottie. ... get some beat S3 body and transfer the focus screen from an S3. I kind of doubt it, but I might run it by Eric.
woof!
