viewfinder dissapointment

I was a bit disappointed in the viewfinder of my A900 after all the fuzz about how big and bright it was. At first I didn't understand why, it was substantially larger than the one on my A700 after all.
Then I took my old Minolta X700 (from under a thick layer of dust) and put it to my eye..WOW that was (literally) an eye-opener...much larger than I ever remembered it to be. Also way easier to focus manually because of the grittier matte screen.

Anybody know why they don't make them so big anymore? And how does the EVF in A99 compare?

Ideally, the lens captures what the eye had in mind...but the damn thing won't listen.

Re: viewfinder dissapointment

in most cameras the market went with penta-mirrors in the mirror box instead of a prism. having a full frame view through the viewfinder means the whole assembly needs special calibration so to cut costs they only show 75 or 80%. These cameras are all AF now. the AF system requires light be diverted from the viewfinder to the AF sensors so the view is dimmer. That makes the focusing matte which also steals some light from the view too dim to use properly. The A900 had a prism and also is 100% view that's why everyone liked it so much but it doesn't hold a candle to the view from a film camera.

The EVF's have drought us back to a 100% and bright view, and with peaking we essentially have the matte screen functionality.

Re: viewfinder dissapointment

I used the supermatte screen on my A900 and found that it let me manually focus anywhere on the screen even at f1.4 with most lenses.  I can't remember what sony called it, L or M I think, I'd definitely recommend it.

It's the M screen.  I might look at getting one.  I have the L now, which added a grid.

Re: viewfinder dissapointment

I ask because I ordered an adapter to use my old manual minolta lenses on the A900. I'll try the pentax eyepiece magnifier I have sitting on my A700, maybe that will help. Are the M screens still available?

Thanks for the reply everyone!

The screen on old film cameras were designed to make manual focus easier. They has a coarser grind so they were brighter and snapped into focus in a more obvious way. Digital cameras have a finer ground surface which has finer resolution. As far as size, maybe a more power magnifying lens?
