Based on the RAW files that he posted, we know that he did the AF Servo test on the Canon using Spot AF...

Interesting.  Presumably, he doesn't know that Canon recommends against using Spot AF with moving subjects.

Off on a tangent but...
That's only because the spot AF is harder to hold on the moving target, not because of any inherent problem with the AF, isn't it?

back to the deer theme for a moment - another species - the mule deer.

I'll bet the  fish weren't happy to see this bunch show up!
Note the two in the lower right - they swim along with their eyes below the surface.

My 1.4x II teleconverter - terrible resolution.

Unless yours is broken in some way, there's nothing wrong with the 1.4x II.  Usually, the lens is the limitation not the TC.  And, yes, I do have one.

I only use it with my 500 IS USM (the I model) so I know its not the lens. I get better resolution by cropping the 500 than using the 1.4 II. And I'm pretty sure its not a AFMA issue because I can't see any front or back focusing.

According to Thom Hogan, the sensor is unlikely to all that revolutionary, but merely a reworking of dual pixel technology with improvements mainly in autofocus. Not so much in IQ.  :P  ::)

"I think that’s likely more dual-pixel focus ability, only better integrated into the calculation engines this time. In other words, I expect the sensor change is mostly about focus performance, especially with video and Live View".


That would be SOOOO disappointing.

In response to another comment on backpacks - I basically live out of my LowePro 600 AW.

EOS Bodies / Re: One other hoped-for feature on the 7D2
« on: July 28, 2014, 08:34:08 PM »
In order to keep my shutter speed fast (for my 400mm lens without IS) and an F-stop a little less than wide open for a greater depth of field, I need to set the camera to manual. With those two settings fixed, in order to adjust the exposure, I need to manually adjust the ISO.

With auto-ISO enabled, the Manual camera setting isn't really fully manual. It would be great if the camera allowed exposure compensation for the "not quite manual" setting where shutter and f/stop were fixed but ISO was automatic.  [BTW, let me know if this is already a feature and I missed it somehow.]

That's assuming we get the high end ISO performance we're (at least I'm) hoping for. My basic process with my 7D is set the iso as high as I can stand it (which is usually 400, maybe 800 in a pinch) and then just use
Av or Tv, depending on whether I think dof or shutter speed is more important.

I havebeen seeing this doe in the same spot for 3 days now so I threw on my camo and stalked to the edge of the bean field where i saw her yesterday. It took almost 2 hours of crawling but i got to within 10 yards . I hope she makes it through another hunting season , she is real pretty to look at.


Which brings up the question that's occurred to me often - how much do we photographers acclimate wildlife to humans?

EOS Bodies / Re: Eos7D mk2, How EXCITED will you be if . . .?
« on: July 22, 2014, 09:41:46 AM »


Time can be a factor, but gear is not immaterial. If I wanted to get a shot of bears, I'd much rather have a 1DX/5D III and a 600/4 + 2x TC, or a 7D and 600/4, than anything else.

Think I'd go for a helicopter first myself  ;D

You wimps!   ;D
...

A bit off topic, but...
Like most tourists, I don't think you understand how quickly things can go bad in the wild. Sure, black bears seem more timid than grizzlies but many animals may look quite docile and then the situation changes in a heartbeat.

I dunno. I've read the subsequent DPAF patents, and there isn't anything remotely revolutionary in there. Mostly just using different sized photodiodes for the AF part, and a means of increasing sensitivity for AF without reducing IQ. If that's all Canon's got for the 7D II, they are going to take a HUGE reputation hit...and they HAVE to know that... (If they don't, then they've totally lost touch with their customer base, and I am seriously hoping that's not the case.)

Are you suggesting that the people here are representative of Canon's customer base?  I see lots of clamoring for better IQ on forums but until the 70D, the 7D remained a strong seller.  I'd bet a 7DII with 41ish AF points and 10 fps, and a 24 MP DPAF sensor similar in IQ to the 70D, would sell quite well.

It may sell, but I think it would still hurt Canon's reputation. To date, they actually have a very good track record of listening to their customers and delivering on their customers demands. Both the 1D X and 5D III are excellent examples of that...Canon pretty much NAILED both on the head, delivering exactly what their customers wanted.

...


I agree, jrista.
Maybe the 7DII with 41ish AF points and 10 fps, and a 24 MP DPAF sensor similar in IQ to the 70D, would sell quite well but I wouldn't buy it. Nothing in that list (except maybe the 41 AF points) is "must have" IMO and I'd be really disappointed if my 2009 7D is really the best Canon can do for higher ISO in a crop. And, I don't see the attraction of the DPAF at all. I only use live view if I've got a relatively stationary subject and that's to zoom in and use manual focus in a situation where there is a lot of brush to confuse the AF.
I'll bet I've used live view auto focus in less than 1% of my photos.

These two points seem antagonic:

*Quite high MP count
*Greatly improved low light and ISO / noise performance



Those are NOT opposed to each other!  At the same final size, more pixels on the same size sensor will produce LESS noise at the same final level of detail, not more (this myth got started because of comparing at 1:1 rather than constant final size and detail level).  The only exception is at very extreme ISOs up into the 6 digit range.

Cue jrista...

So, finally got around to picking up a Canon 5D III.
...
Thanks for the post. I've been holding off buying a second body for (literally) years. I shoot a lot of wildlife and your assessment is making me lean towards biting the 5Diii bullet myself.
although, I've only got an old 500, not that snazzy new 600 :-), so my focusing might not be as quick as yours.

Young female Bobcat portrait.

Canon 5Diii, 400 DO, ISO 400, aperture preferred, f7.1

Steve and Eldar,
I'm envious - I've got bear photos but very few cats [outside of our housecat:-) ]. Nice work.

A couple of photos from Trout Lake in Yellowstone. No otters but a couple of cooperative waterfowl. I hadn't noticed the serrations on the golden eye's beak before - the better to hold the fish, I guess.

7D, 500mm IS USM, iso 400

I've got the Lenscoat Raincoat Pro for my 7D and 500 f4. I like it much better than the cheap plastic.
