p.48 #1 · Sony A7 and A7r Full Frame with Canon Lenses
I was just thinking of all the returns or short sales if Canon users end up not liking the A7R with the metabones smart III adapters. It might be a good time to snap up a cheaper FF. I for one love that Sony is releasing a DSLR like ILM. I think AF will be slower with these adapters but overall, it's still a great value proposition over owning an actual SLR.

I think they have been hamstrung by their antiquated steppers and the refusal to outsource for new ones and instead keep soldiering on while they developed better ones. Probably also did not have the talent to come up with improved DR etc. One problem Canon faces is that they have very few research scientists and nearly everyone is an engineer with no PhD and no fundamental understanding of real research. Obviously they can do research, but IMO they are top heavy with engineers.

Would you feel more comfortable if they had more engineers with PhD's, or is this a "physicist vs. engineer" thing?

I handled the A7R with the metabones adapter and a Canon 24-70L and AF is slow. IMHO the A7R with the adapter is perfect for Landscape, Architecture or Macro users that mostly work with the camera on a tripod and manual focus using live view. For that it is superb and as we all know, Canon has nothing that comes close to the A7R in regards to image quality at base iso.

Or a long while as Nikon/Sony don't seem to be able to make any in roads into Canon's market share. The latest financials would seem to say they are actually doing worse even with all their sensor technology.

The average buyer, is not a total tech head like the average forum user. People will buy if they like what they see and clearly they like what they see based on sales, and don't get hung about about things like low ISO DR and shadow banding. It's not like 11.7 stops is a pathetically poor DR, it's enough to allow me to do probably 80-90% of my shots without resorting to double exposures or HDR. Maybe for the Sony sensor it would mean 95%.

Sneakyracer . . . but for any "run and gun" faster paced hand held assignments or travel, using Canon lenses? Not so good, huh? More like shooting a G-series? That's doable, so long as posing people isn't an issue, or any kind of activity (not Action).
Does that seem a fair assessment for non-tripod use?

When posters are saying AF is slow when using a Canon lens on the A7r does that mean it's slow for action or also slow for studio? I am interested in this for portraits and will use my 1DX for action.

I would love to test the A7R with a combination of EF lenses to determine the extent of the "slowness" but I am pretty sure it is too slow for action sports but OK for studio portraits from handling and using the camera for a few minutes. The accuracy is another factor il have to test for. But Live View Focusing (AF or MF) is much nicer when you can look and compose the image through an EVF rather than the rear lcd and the Sonys have a very good EVF.
Looking forward to seeing more hands on reports with Canon lenses.

I think that's wrong. If a company waits to devote resources adequate resources to R&D until it's losing market share, it's waited too long.

No company can be innovative in every aspect of the market. Canon is working in lots of areas to lead the market. Currently a group of camera users aren't happy with one aspect of a DSLR system, that doesn't mean canon is waiting in all areas.
Here's a link to a sooc jpg from the A72. Impressive detail for a jpg. A7R Sample
Interesting observation form dpreview. The A7R was found to consistently focus faster had far more keepers than the A7. Looks like the A7 and in particular the 28-70 kit lens might have a problem.

Canon is super innovative, they just released a white camera!
I have no interest in a white camera but whose to say that this won't sell. Apple released a gold iPhone and the sales on that took off. Believe it or not people buy on form over function. Canon is a business. If a white camera sells then it is a success.
I don't think being "super innovative" is sustainable. It happens in short spurts with long periods of refinement. Not even Apple who prides itself on being cutting edge sustains it every single release of their products.
No doubt Canon's sensor tech for low ISO/DR has fallen behind but they still keep pushing the envelope for high ISO and that's where most people want improvements anyways. For all the clamoring on this forum I have still yet to talk to a photographer who said they desperately need better low ISO/DR.

Thats an interesting observation, everything I read to date indicated that the A7 would focus faster. I had a chance to handle both models a couple of weeks ago and honestly I really didn't see a significant difference in focus speed between the two. In the end for my purpose it's pretty irrelevant based on my intended use for this camera, someone said it before "mountains and tree tend to move pretty slowly"
