Hello,

Just found your great comparison of VF and LV.
Pretty interesting to read doubts about a700 and future of the sony a when the a55 is reviewed with slt and the best LV at the market.

It depends on the exact screen and camera model. You’ll find that 2.2 may apply to the full frame professional screens, but a figure closer to f/4 will apply to APS-C entry level (this is the usual situation anyway, with all camera makes having a range of screens and finder types). When mirror prisms with low brightness are used, they tend to go for a more transparent focus screen. I notice on the Sony Alpha 380 that a less transmissive screen is fitted, perhaps to enable the live view system to work better off-focus-screen. This results in the visual effect of the f3.5-5.6 kit zoom darkening as you zoom. Other models using a different focus screen don’t darken the same way and presumably have an f/5.6 focus screen (in the terms we are talking about).

What you are noticing in depth of field issues is that Canon viewfinders start at 2.2. There is no difference below that. You can’t figure it out very easily with the automatic Canon lenses but I shoot a lot of vintage glass (mainly Olympus) and the viewfinder only starts to darken after 2.2. After 2.2 the viewfinder is accurate.

I found this all very interesting. So interesting that I did some comparisons using my Sony A-100 & the Minolta 50mm f1.7. In my VF, the DOF looks much more like f8 than f1.7 regardless of where I have the aperture set. Even when I press the DOF preview button, the DOF doesn’t really change. The VF gets dimmer, but no apparent change in the DOF up to at least f8. So, what good is the DOF preview button? Is it any different on the A-700 or the A-900? Maybe this is why Sony took it off of the A-200, A-300 & a-350.

[...] You will see it more easily in the full size file, just click to open; it is a patch to the right of the instrument’s nut (the instrument is a Canarian timple, a Canary Island relative of the ukulele). The overall focus is slightly different, despite a similar 8 degree tilt, as judging the focus and tilt angle on the focusing screens of these DSLRs is next to impossible for reasons we explain in this article.

Nice analysis… I agree with you that sooner or later, LiveView becomes industry standard.

Fyi, I take photo especially underwater. Many divers nowadays still take photo by DSLR inside of its UW housing by viewing the object through viewfinder. But after I use Sony A350 liveview (quick fast, autofocus, really live, set whitebalance/Kelvin temperature and view the effect on screen at the same time…!!!), and how easy it is to capture small critters inside coral while the position to view from viewfinder is limited or when the object position is level with seabottom where you can’t see the object via viewfinder while you want to take the eyes .. liveview make my life easier and safer …. made me think thrice to move to better camera but without (good) liveview.

Hopefully 2009 will be better…
