Re: OVF vs EVF put to rest

Not put to rest, but after having used both most of the claims in this video are true. OVF is still advantageous for certain sports photography however.

Re: OVF vs EVF put to rest

I can't watch the video right now since I am on a very slow Internet connection, however there is no way you will put the issue to rest. There are too many Canikon users that are just too firmly entrenched in their OVF system and they will never listen to a word you say. The only way to convince them would be to take their present system out of their hands for a few days and force them to actually use an EVF based system. And that's not going to happen in most cases.

The advantages of EVF over OVF are much greater than most people realize. I wonder if Sony has a patent on EVF, if so, that could explain why Nikon and Canon have not embraced it. I will certainly not go back to OVF!

Not for the trained EVF user! After learning the EBF to use shooting action should not be a problem! Not more than with an OVF camera.

I often hear this claim, but not from experienced EVF users.

Re: the video advertisement

Three questions:

1. This is an advertisement. Advertisements are made to persuade. What persuasion is this advertisement pushing? Why was the decision made that this persuasion was necessary?

2. Why was the name "Tru-Finder" selected. What does the foregrounding of "Tru" tell us about the product being advertised?

3. The real question for me. I can see changes in the lightness of light objects caused by ripples in water below the objects in the a900/a850 OVF (e.g.: birds or grasses on a shore). I cannot see that in the a77 EVF. Is there an EVF on the market that delivers anything close to the absolute luminance fidelity of a large, bright OVF such as the ones in the a900/a850?

I agree with you Karl. I own both an EVF and an OVF based camera and I always go for the EVF camera first. There are plenty of Canon and Nikon based EVF cameras, but they are all bridge cameras. I think Canon and Nikon are hoping that Sony and the EVF based DSLR will go down in flames so they won't have to come out with new systems.

For canikon to get a EVF then it has to be a mirrorless camera with really good on sensor PDAF which canon sucks at.

To address your 'real question': Yes you can see the 'absolute luminance' in your OVF, but there is no sensor, and there probably will never be any medium, that can capture it! So why is that so important to see in the viewfinder? At least, the EVF provides a more realistic view of what the sensor is actually recording, and even lets you see the effects of any adjustments that you make to the image you are trying to capture. If you want to see the 'absolute luminance' of a scene, just look at it with your own eyes.

And in fact the beauty of the EVF is that it specifically doesn't give you the "absolute luminance" of a scene. Those with OVF's will go on for years taking blue tint pictures because they forgot to reset their WB, or wondering whether to wick the exposure comp. up/down, or guessing what effect one of the Scene Modes might have, but those days are gone for Sony users.

The current generation of EVF needs to be improved of course, but I'm so done with absolute luminance.

Uh-huh. A short promotional video is going to 'put to rest' the debate.

^^^ This!

While the video is compelling, and the EVF is evolving to become better all the time, the bottom line is a very good EVF is much less expensive to mfr than an optical prism viewfinder.

Most likely the very best solution would be the combination of both, electronic overlay / OVF, but how would that save Sony (or anyone) any money?

Viewfinders are not a religion, no extra points for persuading your friend/neighbor to come over to your side of the argument.

Re: OVF vs EVF put to rest

Ad or not EVF is proven to be better than OVF in many applications. It is the same for people who kept saying "I will never go digital." At the end of the day, if you can't embrace advanced technology then it is your loss.

My a850 and a900 each capture this difference easily and clearly. On what basis do you claim otherwise?

Don't get me wrong here -- I bought and use the a77 specifically for the advantages the EVF provides (primarily live view and the articulated LCD). The EVF is a great tool. It has, for my use, a fatal flaw: the DR is far below not only what I see, but also below what the sensor records. After a few weeks with the a77, and knowing that Sony was not going to produce another OVF as good as the a900/a850, I purchased a used a900 as a long-term backup for my work.

I don't imagine I'm going to get any traction with you here, but imho you are refocusing the light of this discussion on something irrelevant. You add nothing to the discussion by turning this into a litmus test of individual's judgement. (For what it's worth, "I will never go digital" is very different from what you seem to think it means. It does not mean "Digital is unworthy" .) Additionally, no-one is arguing that EVFs are inferior to OVFs in many applications. And lastly, the a900 OVF is the supreme example of OVF technology. "Technology" does not equal "electronic" .

Re: Just tried the EVF in a shop?

I wasn't much experienced with EVF at the time I shot these (actually, my first low-light action shots) but it worked well for me on my A55.

I didn't plan on being there, so had my 16-50 SSM (hence, substantially cropped).

Re: the video advertisement

The problem is that an overlay wouldn't get any information from the main sensor while using the OVF in a classic DSLR design.
