Most Cameras (even the T3i) allow you to set a shutter speed range when using flash - did you check the settings in the custom functions? Sounds like there is no limit set on your 5D3

[...]That or a local camera store which rents out if one is nearby - a coworker did that 2 weekends ago and got a phenomenal rate
Good to know about borrowlenses - they have a pickup location near me, so no shipping charges if I ever do need to rent something.
I may be missing something, but I am perplexed by the suggestion of having your body calibrated to the lens. If you have several lenses which are off at varying +/- values, then should we have a dedicated body for each lens?That is taken care of - cameras store AFMA values separately for each lens (e.g. +5 for your 24-105, -2 for your 16-35 etc). With newer cameras and lenses, you can even store different AFMA values for different copies of the the same lens.
I learned to like it because I now can have AI Servo on all the time. If I need to focus-recompose, I just take the thumb off the button. No more need to switch back and forth between One Shot and ServoThanks - you learn something new every day! One more reason to love back button AF...
Neuro, I took your recommendation and tried the back button AF setup a few months ago. I used it for about a week (personal use) and switched back to normal on my first job (I would have been terrified otherwise). I like the idea, and it's very useful in situations but not sure I can use it for long enough to get really comfortable with it.
Impatience, perhaps? Though my 85 won't engage manual focus, even after spinning it. My point was if that's my only complaint, it's a very small one and that the 85 is a wonderful lens.AFAIK the camera has to be on for the manual focus of the 85L II to engage. In other words, you need to set it to MDF before you turn the camera off.
ahab,yes, it definitely helped me. Only counter-intuitive thing in the simulator is that focus distance gets shorter as you move the slider to the right (maybe not for view camera users).
That simulator is very cool, I haven't seen it before, excellent link, thanks.
See here for a couple of cool gif's and more info http://www.northlight-images.co.uk/article_pages/using_tilt.html
Basically the longer the focal length the more tilt you need for the same effect, AND, and this is the really important bit for a potential macro tilt lens use, the closer the camera is to the plane of focus the more tilt you need. Bear in mind a 90mm TS-E needs 36º of tilt with a J distance of 6", current Canon T/S lenses have 8º of tilt.
True, but I don't think it takes 18MP stills. I'm not an engineer, but often you have to optimize for one or the other. Both at the same time is difficult.Because it is not trivial to process the larger amounts of data per second. Processors need to be fast enough and be able to dissipate the heat.
I can see that, but the new GoPro does 4k.
Interesting, I've always assumed it was closed loop, since well, that's how I would have designed it, and all the pieces are there to close the loop. Perhaps the focus speed is hit too hard, but frankly I can't believe that since the second "look" would be nearly instantaneous.If it was closed loop, with a second look, we would be only a few steps away from a self-learning AFMA built in into the camera. Now that would be nice, wouldn't it.
That said, I'm no expert, I'm sure if it's true that focus using the phase detect is open loop, Canon has a very good reason for that.
