Discovered to day that my new Tamron tele-converter does not work with my new 7D Mark II. It works fine on both my old 7D and on the 6D. I use it with the 70-300mm L F4-5.6 lens. Hope that a future firmware update allows me to use it.

A firmware upgrade of the *camera* to make it compatible with a 3rd party tc? Forget it. Same problems appeared on the 5d2 and 6d. You can try disabling afma, that helped on some camera bodies to prevent it from locking up.

Issues like this are only solved by the 3rd party, and if the item doesn't have a software update interface (like newer Yn flashes or Sigma lenses) you're hit for six. Probably they'll do a silent or official update of the tc sooner or later so you can sell on your then-old version to someone with an older camera.

I am going to have to re-read the AF system manual and see if the various setting have any impact.

Good idea, the detailed af settings are crucial when the af might be confused, either by objects getting in betweeen the camera and your subject, or when tracking losing sight of the tracked subject for some period.

I might add: In a two decades from now when we're all happy mirrorless shooters, you just install a software-addon module to your camera "snowflakes v2.3b" and all white points moving downwards are ignored :-)

Has anyone else had this happen, and if so, what did you do?

Interesting, because I would have expected the exact opposite: My single-point 6d/60d completely screw up in falling snow because with just one piece of information, the camera cannot decide if it's a subject or "gras/snow/... in front of subject" lock. I'd guess that with multi-af, the camera should be smarter, at least in theory.

this is actually a decent shot but worth that much money?  :o

I don't know any other of his work, but I find this to be an excellent picture, and he had the good sense to put a meaning it other than "I happened to shoot this the other day" :-)

As for the money, obviously(?) high-priced art isn't about private people spending millions for their personal pleasure, but for social status ("Look, I like good art! And I can afford it!") and future investment.

If want "wtf!?", I just read about this being the second most expensive picture ever. I'm really lost for words, probably because I'm German and for this domestic river a lot of associated images pop up in my mind - but this isn't one of them :-o

If they can't deliver better AF than the A7II, there is a whole lot of need for the 5DIV...

What exactly is left to get better anyway with ff phase af? The only obvious difference is the size of the af array, i.e. the spread of the af points to the edges. But looking at all ff cameras, Canon or not, this seems to be either very hard or very expensive to do.

Thus I imagine the 5d4 advances will be different:
* minor fps advancement
* minor advancement in res
* but dpaf and 120fps@hd for video
* 7d2+ fw features (anti filicker, intervalometer, ...)
* 7d2 hw features (gps, sealing)
* 5d3 bugs fixed (slow sd writing, no af indicator while tracking).

The real question for the 5d3's success is if there will be any visible advance in sensor iq, at least to 6d/1dx/7d2 lack of banding and maybe 0,5-1ev better snr. Combine that, and it's solid upgrade like Canon likes it.

Unfortunately with my current camera (6d, 5d2 is the same) I'm getting the worst of both worlds: mediocre af system and mediocre mf capability at the same time. These cameras are ff in name, but even my old film cameras (620, rt) have a far bigger and brighter viewfinder making mf more accessible.
On the 6D you can use the Eg-S screen. That makes manual focus very simple.

I didn't try that (I've got the grid screen installed, the eg-s wouldn't work with my f4 lenses in dimmer light, and from what I read the real difference is for faster lenses than f2.8.

But I imagine it's as much matter of magnification as of the screen displaying the dof - at least 1d users wrote on CR that their vf makes mf much simpler as it's simply larger. As written above, looking at my old film cameras I tend to believe that.

You may find more value in keeping the 60D as a backup/second body rather than selling it or trading it in.

+1, the 60d makes a nice backup for the 6d as it's got the same usability. Things break, the 6d isn't as sturdy as pro-line cameras, and any repair w/o high cps will leave you missing shots.

The crop camera is also better for macro (working distance), getting more reach with your long lenses and has the swivel screen for video & awkward tripod work. Last not least, the bit more fps vs. 6d can make a bit of a difference for sports and "get the right moment" shots.

Selling the 60d now won't leave you as a happy camper as the market is flooded with these cameras, you missed the opportunity to sell before 70d or 7d2 release.

It's a Canon so most of the menu system, button labelling is always familiar but I still read the manual and refer to it from time to time just to make sure I'm getting the most out of it.

The problem with the Canon (and probably all other) manuals is that they try to be accessible to everyone, including instructions on how to turn on the camera. If they'd split it up into a part "advanced settings, faq and this is what people usually miss" part, I'd rtfm more often.

I too have read about the metering, and am led to believe this is because the metering is done somewhere in the viewfinder, the eyeball side of the focus screen, hence we are supposed to use the cover on the eyepiece when not using an eyeball to cover it.

Yes,  the same reason why Canon is rumored to be really unable to make the 5d3 illuminate the af points while tracking - it throws off the metering. With the larger prism/vf box of the 1dx it seemed to have worked.

Unfortunately with my current camera (6d, 5d2 is the same) I'm getting the worst of both worlds: mediocre af system and mediocre mf capability at the same time. These cameras are ff in name, but even my old film cameras (620, rt) have a far bigger and brighter viewfinder making mf more accessible.

Ps going back to work now only led astray for 7 mins.

Smart choice, if I'd be even packing groceries for all the time I spend procrastinating on CR, I'd own a 1dx+600L by now :-p

I hope this is not a stupid question, but why would the focus screen affect AF, isn't AF done from a separate sensor in the bottom of the body via the secondary mirror, therefore not going anywhere near the focus screen?

Good point, thanks for thinking. I stupidly took this information from an internet customer review :-p and we all know how much these are worth. You're correct, the screen shouldn't affect the af system!

But it does seem to affect metering because the Canon fw settings for exchanged screens don't seem to fit the 3rd party item, I've read this more than once :-p

I've been using the 7D since it came out and I just recently purchased a 5Diii based on all the comments that ff is much better than the APS-C. My experience - not so much.

A common fallacy if you ask well-off enthusiasts, I'm afraid.

but for static things like landscapes and night photography, I think the 7Dii would do the trick.

I depends on how much you postprocess the shots and if you compete with other photogs ft. ff gear. But for general shooting crop is just fine, of course it is, otherwise manufacturers wouldn't sell that many gear with smaller sensors.

I'm not sure whether others do this, but if I pixel peep and notice issues, or if I know that horizontal or vertical lines and contrast are going to affect AF I rotate my camera, lock focus and shoot again.

I'm very used to it because I did just that for ages using my old film Canons 620 and RT with only one non-cross sensor :-\

Problem is that rotating the camera takes time, so with wildlife this is awkward. Furthermore, rotating introduces a recompose focus error because you move the camera, but you'll only notice with thin dof and/or fast lenses.

I was already wondering when you'd show up in this thread :-)

I think the cost of film taught you to be more careful about taking shots.

Actually, the cost of film taught me to stop shooting because I couldn't afford it anymore :-o ... I only started again after digital cameras were good enough so there was no need for yearly body upgrades anymore.

Case in point - the shot below.  Not a great one, but a very difficult one with a handheld 600mm focal length on a moving boat through lots of foliage with a baby that slipped off its mother's back about 5 seconds after we spotted it.

Great shot and amazin iq, given the circumstances. It's so darn difficult to get everything right with wildlife, and Murphy's Law tells us that "the value and uniqueness of the shot is proportional to the likelihood of some grass or similar rubbish being in the frame" :-p

I'm not sure I quite understand the "only a f2.8 overlay" comment. Are you referring to the added f/2.8 vertical line sensing capability?

Yes, that was me being overly brief - I'm indeed talking of the strange 6d/5d2/... af point contraption with a slower cross af point overlaid with a single, faster af line. No idea why didn't put a full double-cross sensor into it, either marketing and/or tech limitations on release of the older cameras.

Couldn't sleep.  That's nothing new though - I don't want you all to think it's related to this.

I understand your predicament, but if you're finished shooting test charts, don't let yourself be detained and get out, shooing something alive ...

... crawling around the frozen scenery during a full moon night, shooting wildlife will help you worry less about pixel sharpness and make you sleep when you return home, you've got my word on that :-)

Note: Sorry to spam the place with horsie shots, it just seemed appropriate here somehow :-o

I wonder how many people don't read the manual and then complain about what the camera can't do or does poorly?  ;D

I'd really like to know the actual number, but I guess it's very high - the very reason manufacturers and esp. Canon are that conservative with new software features and would never adopt advanced features like ML has. The amount of work and bad viral press ("crappy camera ain't working") would be too huge to compensate for the amount of customers won.
