Watched the video.
So what you are telling me is that the 7D2 with the right lens (at 100mm) is better than the 5D3 (with the wrong lens) at a similar focal length.

I didn't watch the video.  But if the OP is comparing the 7DII + 70-200mm f/2.8L IS II (arguably the best zoom lens available, at least the best under $10K), vs. the 5DIII + 24-105mm f/4L IS (a good lens, yes, but not nearly the quality of the 70-200 II), then I suppose I'll have to fetch my broom and declare shenanigans.


With the 7D2 and a 70-200mm lens, I can get 360mm framing with 5D3 ISO performance in a lightweight package.

If you're suggesting that image noise of a 7DII image and a 5DIII image with same lens/distance cropped to APS-C FoV are similar, ok.  If you're suggesting that the high ISO performance of the two cameras is similar when comparing the same framing (e.g., a longer focal length on the 5DIII, aka 'using the right lens'), then try the comparison again once the effects of the mind-altering drugs have worn off.

I'm thinking about buying the 300 and a couple years down the road adding a 600.

I bought the 600/4 II a couple of years ago, and the 300/2.8 is on my short list.

Adding in a crop body gives another 1.6 factor.  Thus we get 300 f/2.8 to 960 f/5.6 f/9.  Both of the shots below were handheld.

I fixed that for you.   ;)

Great shots, BTW.

Clearly it's a problem with the lens.  You need a better one...



 ;)



I, too, am passing on the 7DII.  As I've stated previously, the main advantage of APS-C is lower cost.  Having owned the 7D, moved to the 5DII for everything but birds/wildlife (because the AF of the 5DII wasn't up to the task), then moved to the 1D X and selling both the 5DII and 7D, I don't see going back to APS-C, except when the constraints of an outing preclude a full sized camera, and in that case the 7DII would also be too big (and that's where my EOS M comes into play).

Lenses / Re: What's your favourite focal length?
« on: November 19, 2014, 07:40:13 AM »
My favorite focal length ranges from 14mm to 1200mm, depending on what I'm shooting.

Yay!  Another one-number reduction of the many parameters of image quality, which obviously says all that needs saying about camera performance.  Now we can all decide if the 7DII is a good camera or not.  Woot!!!

Anyone have any idea/opinion whether an L plate (RRS) for a Gripped 5D3 would fit on a Gripped 7D2? The grips look pretty close. I don't use it all that much. It would be nice if I could use it for both.

Call RRS and ask, but it's pretty doubtful.  There are almost always subtle shape changes, and the RRS plates are custom fit.

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

... I fabricated a flat target from 5mm thick yellow craft foam and narrow black masking tape so I had a high contrast target.

Apparently I built a focus target that cameras can't focus on. Will contact USAF to see if they want to use it in their stealth technology.

Rod, would you be willing to post a picture of your DIY 'stealth target'?  Thanks!

Weren't you paying attention?  It can't be photographed.  Sort of like a genuine UFO.

LOL.  I'm sure Live View would work.  Perhaps even that archaic technology called manual focusing.

The accessory grips have always been 'thick' even before the tray for the LP-E6 batteries.  I find the vertical grip ergonmics of the 1-series bodies much nicer than a gripped body.  On the back of the camera, the integrated grip of the 1D X is smooth, compared to the back of the gripped 7D where the bottom of the grip protrudes backwards.

Sounds like a plan.  I would have advised against swapping the 70-200 for the 100-400, but not after seeing you adding portrait primes to your kit.  I do think the 17-55/2.8 is the best general purpose zoom for APS-C. 

Do think if you really need 50-85-135 lenses in your kit.  Not that what others' do matters, but the usual trinity combinations are 35-85-135 or 24-50-135 (I have the former, but I use a FF body).

Photography Technique / Re: contrast in settings on camera
« on: November 16, 2014, 08:32:19 PM »
When you increase or subtract contrast in the picture styles in camera: What mechanism does the camera use to facilitate that change?

Lets go simpler... the changes are facilitated with the use of light and manipulating the exposure (?). What does the software tell the processor to do to the light, more light less light more exposure less exposure?

Exposure (shutter speed / aperture / ISO) aren't affected.  The contrast setting expands or shrinks the overall range of tonal values in the image.  Basically, increasing contrast makes bright tones brighter and dark tones darker.

Lenses / Re: EF 35mm f/1.4L II to Finally Come as Well? [CR2]
« on: November 16, 2014, 05:54:32 PM »
    Voigtlander is actually selling a 35mm f/1.4, just as Canon, but in a different size…here is a picture to show you the difference in size…both of them are 35mm and f/1.4.
    [/list]

    The Leica M mount has a flange focal distance of less than 28mm, meaning a 35mm lens doesn't need to be a retrofocal lens design; that's not true of a 35mm lens for the EF mount.

    Something pressing the shutter button while the camera is stored seems most likely.  Do you put it away on standby?  Are the images before and after the black frames consistent with the camera being stored then?

    Lenses / Re: Advice needed on possible 100-400 L Lens Trade
    « on: November 15, 2014, 02:59:08 PM »
    With the 100-400 mkii coming to the market... there should be a number of mki models going up for sale.  I did a whole exercise estimating that the sale price should be around $850 in a few months... but then rebounding back up to around $900.

    I sold mine a few months ago,for considerably more.  Good luck and timing on my part, I guess...
