None of these are arguments against mirrorless, e.g, a Digital Rebel with an EVF and hence no mirror. This is where I think Thom is making his prediction - that "soon" the mirror will be dropped for low-end EF-S and Nikon DX bodies. On the other end of the price spectrum could be a 1DHS or D5HS (High Speed) body with an EVF and extreme frame rate. What's left is to quibble over the definition of "soon" for the first model to appear (next year, two years, five years?) and how long will actual DSLRs with mirrors/optical finders be in the lineup (five years, ten years, or more?)

At this point mirrorless has no advantage and has disadvantages compared to Canikon solutions.

The difference between you and Thom is that you are thinking of mirrorless as only Fuji/Oly/Panny/Sony.

What advantage does removing the mirror from CaNikon bodies give them if they continue using the same mount? I don't believe this offers much size or weight savings. It just makes the camera cheaper and less functional, IMO. Again, you have the same flange distance, which means the bodies are still going to be large.

If they change the mount, will they have market penetration for a camera/lens system that's not compatible with their existing DSLRs?

I'm asking a serious question here. What kind of changes can they make if they remove the mirror but maintain the same mount? And what point is there in going to mirrorless if you have no major size/weight changes, aside from money savings?

I think the last four words of you comment provide one serious answer to your question.

Your question is also based on the assumption that OVFs are better than EVFs. Thus, the other serious response to your question is that EVFs will continue to advance in quality and will be eventually be preferred by the majority of users.

This is obviously a hotly debated topic and Thom provides a good summary of where things currently stand and where he thinks they are headed.

The optical (OVF viewfinders) versus electronic (EVF electronic viewfinders) debate is an intense one. Clearly some people prefer one over the other. But let's not lose sight of a few things (pardon the pun): neither OVF nor EVF is perfect. OVF over the years has been optimized for brightness and overlays, which comes at the expense of seeing focus detail. Position of the eye at the viewfinder is also a variable for OVF (try it: while looking at an edge slide your eye from one side of the viewfinder to the other; so much for 100% view). OVFs will be dimmer with slower lenses, too. EVFs need more brightness finesse than they currently have (too easily kill night vision in dawn/dusk shooting). In terms of pixels, we're already at SVGA levels with most EVFs, while a few current ones are at XGA levels. In 2014 we'll have EVFs appear at about SXGA levels (1280 x 1024, or >4m dots). EVFs definitely show 100% view, and they can be as bright for an f/5.6 lens as for an f/1.4 one. Still, today we're in an area where OVFs are mature and accepted, while EVFs are maturing and not as accepted. Within a couple of years, I doubt that we'll see a lot of resistance to EVFs, though.


Except there's nothing that prevents incorporating an EVF into a camera with a mirror. I'm not sure how practical it is or if you could do an OVF/EVF hybrid, but a mirror doesn't preclude an EVF and an OVF doesn't preclude an EVF either.
