Animal Kingdom / Re: Red squirrels
« on: Today at 08:26:13 PM »
those are really nice shots, the red squirrels we have here in the u.s. don't have those comical ears. they look more annoyed than suprised but they are still entertaining to shoot.

Your 18-35 works really well at 35 on the 6d, its about as good as the 35 art in that respect.

Sigma 18-35mm f1.8 Art is for APS-C only I thought.

Maybe there is a converter... and there is a crazy amount of vinetting...

no converter is needed. sigma lenses for canon are ef mount so they fit on ff. the image circle covers the ff sensor at the long end of the zoom range. the vignetting at 35 is correctable with software.

Third Party Lenses (Sigma, Tamron, etc.) / Re: Sigma 120-300 f2.8 Sport

i have tried the lens with most of the available tc's, (canons, sigmas. kenkos, promasters) i would say that i use it 50% 1.4x, 25% 2x and 25% bare. i think the canon 1.4xiii and 2xiii are good. i have had the new sigma tc-2001 for a while and think its a bit better than the canon (about the same sharpness but less ca and faster focusing) i just got the tc-1401. my initial impression is favorable. if you already have the canon series iii converters then use them. if you don't and are buying tc's specifically for this lens then get the new sigmas

adult eagle 70d canon 1.4xiii (420)
immature eagle 7dii sigma tc-2001 (600)
crane crop 7dii sigma 2001 (600)
crane in field 70d canon 2xiii (600)

ps.  the sigma 2001 and the kenko pro 1.4x stack and look suprisingly good on the 6d, its 840 f/8 and still focuses pretty fast. its not the camera i use for long shooting but it might be a pretty useful setup on a 5diii?

I just picked up a like-new copy of this lens, and so far, am loving it.
One the positive side:
1. Solid, Beautiful lens.
2. Image quality is great!
3. Zoom is a huge advantage over prime 300.  I can cover home plate and first base from the same location.
4. Internal focusing, and zooming.
On the negative:
1. Heavy, more than a 300mm f2.8 prime.
2. Focus does not seem quite as fast, well vs my Canon 70-200 f2.8, which is VERY fast.
3. Zoom ring requires some effort.  You can't spin it with one finger.  it's big.

Nice shots. If you haven't done so already, get the dock and update the firmware. It is faster focusing after the update. Also go to your custum settings and set one of your custom modes to speed priority. That mode is much faster than standard and the accuracy seems fine. That's what I use on bif (speed priority, moderate is view,focus limit 30' up)

EOS Bodies / Re: Using full frame lens on crop body cameras ?
« on: December 14, 2014, 09:26:10 PM »
There is some discussion about using the 16-35 f/4 on a crop body. If you already have one and want to use it for that great but don't buy one for that. The Sigma 18-35 is much better. It is sharper and its f/1.8 so you can get decent background blur in a normal zoom which is difficult with other lenses on aps-c.

The article says to make sure you have the latest canon firmware installed. Check that first. For the 6d you don't want the latest version but the prior instead.

EOS Bodies - For Stills / Re: 6D vs 7D mark II
« on: December 10, 2014, 06:51:31 PM »
here is the 6d 16-35f/4 (16mm) and 70d sigma 8-16 (10mm)

they are both good. the ff combo is better in low light but for shots like this they are very similar.

i use the tamron and think its great on either ff or a crop body. its better if you stop down to f/8
What focal length and f-stop were these taken at?

The nuthatch is 7dii 400mm f/8. squirrel is 70d 600mm f/8

Thanks, I will give it a try. The dual ISO feature sounds great. I think you lose some detail in the highlights but that's better than no detail because its blown out

Is regular ml different from nightly builds? The only download link I can find is for nightly builds and that sounds like beta?

EOS Bodies / Re: Focus problems with the Canon 7DII?

The same things were said after the release of the 70D

And the 7D

And the 40D.

And yet - I must be such a lucky bloke - I bought a 40D; and a 7D; and a 70D; and a 7D Mk II, and they all focus brilliantly.

What are the odds?

there is an issue with at least some 70d's having af problems where using a fast lens and the center point the camera would go way off. maybe this is the same thing? just because his af issue seems unlikely that does not mean its not real.

So let me get this straight, in your minds, it is completely acceptable for a brand new Canon user, to open his $1800 camera and expect to know how to MFA a camera, or even know what it is for that matter?

As a long-time Canon user, I have never had to MFA any the Nikons Ive tested (nor Canons), nor would ever do so with any brand new camera for testing because that MFA would not be the same experience new camera owners would have out of the box. Probably something you didn't think of. 

So what do you guys do for a living? Just curious.

afma is supposed to correct for minor tolerance mismatches between the camera body and lens. your are not AFMAing the camera, you are matching the camera to the lens and most of the time it only needed for minor errors. there is something else going on with your setup i think. i would do a reset and try some simple test shots to see whats going on.

So background info, I do a lot of head-to-head camera testing for my youtube channel, Ive done this many, many times, most recently with my 5Diii vs D750, no issues. My main lens is a 24-70 2.8 v2, but I have a V1, and my Dad has a V1 as well. Ran into issues with both BRAND NEW out of the box 7Dii's.

Yes MFA is disabled. Shooting on AI Servo, Single Square, Full High Speed Burst- 10 FPS, Av mode at 2.8, shutter speeds are usually over 1/1000, sometimes all the way up to 1/8000 depending on light. Like I said, this isn't new to me.

Results on the 7Dii's looked as per the image posted, almost all of them, unless the subject is very close. I also did a side-to-side test, both cameras missed nearly all of them.

Tonight I thought it might be the v2 lens, so I grabbed mine and my Dads v1 (24-70 2.8 v1), his 70d and my old 7D. For some tests.

Both 7Dii's consistently missed with all three lenses.

The v2 and my Dad's v1 works GREAT on my 7D and sufficiently good on the 70D, though there were some misses.

If the V2 is working on other cameras, and not any of my 7Diis, Im coming to the conclusion there could be some focusing problems with the 7Dii itself. Maybe not all of them, but the 7D whopped both of them tonight in terms of focusing accuracy with the same lenses they were using.

Ill have to return both of them and I am hoping their replacements will be better.

Just my opinion, if someone spends $1800 on a camera, it should be working right out of the box.

The requirement to have to Micro Adjust a Brand new body, to me, seems crazy.

Ill keep you guys posted, should have the next body in on Tuesday or Wednesday.

this does seem odd. are you customizing the camera before you use it? it is probably something simple that you are overlooking and when you realize what it is then it will seem obvious. i would reset the camera to default and try some one shot tests to see if the camera is focusing where it is supposed to. there was no exif data in the photo you posted. take a look at your photos exif and see what the subject distance is. it looks like your photo is focused at mfd for some reason. the 7dii has a great af system and should have no problem with what you are shooting. the photo below is a gull flying straight at me shot at 420 f/4 normally i stop down to f/8 to get more dof but i was doing this for testing to see how the camera would do and its incredible at keeping up with what you are shooting. you can see that the dof is pretty shallow but the birds beak and face is in focus. the cameras af consistently performs this way.

it just seems unlikely that you would get 2 cameras with some kind of major af malfunction like that.
