Sigma or Canon (50mm 1.4)
I went with the Sigma and have no regrets. No focusing 'issues' on mine with 60D or 6D. Obviously using auto-af point selection will be pointless at f 1.4...

Perhaps you haven't, but others have. Saying it over and over and over. You know what it's called when something is said over and over and over, right? :![]()

And standardised testing rarely reflects actual real world use. Find me a single reviewer/user that has ever negatively commented on 1 series battery life, now show me pretty much any A7 reviewer/user that hasn't. Why the disparity?
Easy, the 1DX is for most applications shot through the OVF while the A7 is forced to use live view or equivalent EVF.

Sometimes I wonder if, Canon ever will get around to putting peaking and zebras inside a DSLR body(without Magic Lantern).
There is absolutely no reason for them not to include it, because it is pure software. And it is not as though they don't know how, because effective versions of those tools have been included in their consumer camcorders for about 5 years. The main reason it appears is that they just don't take video seriously in DSLRs in spite of what their marketing smoke and mirrors claims.
Could a software upgrade enable these features?
neuroanatomist said:Do you normally shoot JPG in Neutral or Faithful picture style? Default sharpness for those is zero. It's 2 for portrait, 4 for landscape, and 3 for the others (scale is 0-7).Marsu42 said:But the result with dpp would look like a sooc jpeg with the same settings, wouldn't it (excluding raw benefits like wb adjustments, dr, ...)? And that would be about the same as the in-camera preview or preview in a cr2 file?neuroanatomist said:Perhaps the fact that TDP's ISO 12233 crops have a very low amount of sharpening applied relative to what is the default for the 60D with major RAW converters? Process the shots you refer to in DPP with Sharpness = 1, Picture Style = Neutral, and everything else OFF, and then compare them to how they look with your standard workflow.

Mt Spokane Photography said:The thing I find interesting is the date of the shots, which supports my theory that Canon was building 7D MK II's as early as last spring in order to have a big supply, and perhaps to allow shifting of production to the next DSLR model.
I've seen production numbers in the range of 30,000 a month quoted by Canon when the 7D came out, and having 200,000 ready to ship to dealers in Mid October means starting in April more or less. That could mean that the next DSLR is likely now in production for deliveries in March 2015.
"Thorsten was given two days in July to photograph the five-week old white lion cubs for Canon ahead of the photokina show (where the EOS 7D Mark II DSLR was officially launched) in September. His 30-minute late-evening sessions would have been sufficient for a portrait shoot or perhaps ample for a product shot, but when your subjects are supercharged bundles of fangs and claws, there is never enough time.
fishprof said:I’ve been lurking here for quite a while and have been learning a great deal from these discussions. I have a few questions about autofocus speed and the relative importance of the lens versus the camera body. I shoot a 7D and I’m primarily using one of two lenses – a Canon 300mm f/4 L with or without a Canon 1.4X TC III or a Sigma 150 mm f/2.8 macro with or without a Sigma 1.4X TC. I shoot mostly wildlife, primarily birds, and macro, especially butterflies, dragonflies, and other smallish nature subjects. I shoot about 50% hand-held, about 50% monopod mounted and I almost always use the central autofocus spot on static subjects. My vision is not very good so I rely almost exclusively on the camera’s ability to autofocus my subject quickly and accurately.
Nothing wrong with relying on camera's AF. That is what it is for! And when shooting 10fps there is no way to rely on the eye to judge focus.
1. I have a sense (but no real measurements) that the addition of the TC to either lens slightly slows autofocus compared to the “naked” lens. Under identical shot conditions and lens/camera settings, is there a reason to expect that addition of the TC would slow autofocus lock? Maybe it is just my imagination?
Yes it does, Neuro has given you the math.
2. I’m thinking about upgrading to a 7DII next year. Will the new and improved autofocus system in the 7DII make a difference in improving the speed of autofocus acquisition with my current lenses? In other words, given identical shot conditions and camera/lens setting, will the 7DII be faster to autofocus than the 7D or is speed going to be limited by the lens system I have in use?
Faster maybe. How much faster? Very little. But overall it will be much better focusing device: Tracking, spread out better focus points etc.
3. I have heard it said that the image stabilization (IS) system actually slows down autofocus lock. One suggestion I have heard (or read somewhere) is to turn off IS when shooting birds-in-flight to allow the camera to lock focus more quickly. Is there any truth to this?
Don't think so. But even if it was, it would be so little that it does not matter.
All are unscientific personal thoughts.
Thanks for your help.

Wishfull thinking...
I understood the 70-300 was optically better than the original 100-400... and didn't have as much of a dust issue... so I could see why one would sacrifice the 100mm reach... but if the mkii 100-400 is optically better than the 70-300L, I'm not sure what benefits the 70-300 has... maybe price... and technically a larger zoom ratio.
