Wrong move Canon. This should have been 4K

A camera from the future?

Canon’s new multi-purpose camera employs an enhanced version of the 35mm full-frame CMOS sensor for Full HD video use that was originally developed by the Company in 20132.

Got into a bit of an argument, would like some ammunition. ;D.

Hard to disagree with that.  The OP seems to be inviting guesses; I suspect he needs better "ammunition" than that.... 

To the extent what we actually own/use matters, I can't help there, either as I have several 85s, 100/105s and 135s.  I suppose I find 85mm more generally useful than the other two, but that can change with what I'm photographing and how I happen to "see" the world that day, so it's hard to have a preference among those focal lengths (I do have a preference among the 135s I own - the image quality of the newish Rokinon/Samyang 135mm f2 is every bit as good as Dustin Abbott's review says it is).

I know I need better data, I am looking.  This is just for a bit of fun.
Does anybody know of a good source of sales data  by lens type?   (please don't post until  the end of the Poll.)
I've been through the Bestseller lists on Amazon for several countries and I will post some of what I found at the end of the poll period.  I think the Amazon data is pretty conclusive, but it doesn't give hard numbers just rankings.
The  most interesting  thing I have found so far is that the Tamron 70-300 was the number one best seller on Amazon France.  (In fact a lot of Tamron lenses are doing very well in France.)  Usually 50mm lenses top the lists. I despair that the Yongnuo 50mm copy was the number 5 best seller in Canada.  I say was because the lists are dynamic and may change, before the end of the poll.
Did you know that the German for bestseller is bestseller?

Just saw this from our good friend Tony;
http://northrup.photo/canon-5ds-r-dxomark-scores-why-you-shouldnt-care/

And I just read the comments.. and came across this:

"The focusing of the a7R II definitely won’t be the same–at least with the beta versions, you can’t select the autofocus point while using adapted lenses…

Let that sink in. During a portrait, the camera might decide to focus on the nose or ear, and not the near eye, and there’s nothing you can do about it.

Without being able to select the focusing point, adapted lenses are good only for the most casual snapshots or when manual focusing."


Makes the camera a total non starter for me - I like my glass, and while I do covet a mirrorless Sony, I think this emphasizes to me that it will be an addition, not a replacement, in my bag - and with a Sony lens.

If true, that really renders all the comments about AF speed improvements with 3rd party (e.g. Canon) lenses moot.  But a) it's with a prerelease version and b) it's TN, so let's wait and see.

According to one post, it's not true.

"Just got the A7 this morning and i have been doing a few quick auto focus tests with the Canon 24-70 F4

First test was with the commlite outside just with single point focus set and it performed really well very quick there was just a very small lag when going from close to far focus, the performance was far better than the sony FE 24-70 on my A7R and it seemed as fast as my nikon d750 with a variety of lenses on.Now i tried it inside with a dimly lit room, the performance went way down lots of hunting and at times you could hear the lens motor ticking away making small changes back and forth not so good.Turning the lights up a bit in the room and it was able to lock focus but again there was a fair bit of hunting.Also the commlite suffered from reflections if the was a strong light source from above like a light.

I then tried the Metabones Mark III outside very fast even a hair quicker than the commlite it felt as quick as the D750 to be honest.Trying it inside and it was definitely better than the commlite it was able to lock focus better although at times it still hunted trying to lock yet other times you could move it around the room at it would lock instantly so from an early quick test indoors i would have to say the auto focus is a bit inconsistent but very usable just after that i tried my A7r with the 24-70 FE and it was about the same in the same dimly lit room.Also the reflection problem isn't as bad as on the commlite.

Ill have to check to see if i am able to update the firmware on the metabones see if that improves things any, the mark iv version would probably be better still.

Over all very impressed the 24-70 works very well i mainly shoot landscape so auto focus speed isn't that important to me."

Agreed with gregorywood. My lightweight go-to option in India and Nepal in 2012 was a 5D3 + 17-40 f/4L + 50mm f/1.4 + 70-200 f/4L IS. That way I could capture wide, normal (handheld in very low light), and telephoto all with one kit. Worked great, and I didn't miss the 24-70 f/2.8L at all.

If you're after the most quality and flexibility at the lightest weight, I'd propose the following:

70-200mm f/4L (IS or non-IS) if mostly outdoor and plenty of light, the IS is unneeded
17-40mm f/4L (or 16-35mm f/4L IS)
50mm f/1.4 or 1.8
1.4x and/or 2x extender

I'd leave the heavy 24-70mm as it is heavy, a narrow(ish) focal length.  I've all but eliminated carrying all three zooms.  I either carry the 24-105 or the other two together when I "know" I will need the reach of the 70-200. 

It ends up being a really light and manageable kit for travel and you still have all the options - weight, reach, quality, low light.

Hope that helps.

I think it still has merit as a manual focus body and for the IBIS, If (and that's a big if) it doesn't suffer from high ISO noise because of it.

The A7Mk2 was basically a step backwards in terms of low light performance if you wanted a fast shutter speed, and only worked better if you could extend your exposure time.
For some reason people don't like to talk about how much sensor noise that camera has.

It seems quite usable at 6400, even if you crop images significantly. 25600 seems usable at full frame.

Nope.  You really can't it seems.

29
Why is the 200-500 a constant f/5.6?  Would have preferred it f/4-f/5.6.

At $30,000, if I was using this for night time surveillance/security then I'd need to set up a second one specifically to watch the first one so it doesn't get nicked.... and then another to watch the second....and then another to watch etc...

That comment made my day hahaha  ;D
