Holy smokes, Jack!

I take that's a complement - thanks.  I've been doing so much grumbling about my 1DX2 lately that I wonder if I've irritated people. :)

Why are there multiple SKU for the same camera? Is it because of factory kit combinations? Or different colors?

Usually for different regions. Ie a different SKU is needed for a box with a US power adaptor to one with a UK or EU adaptor.   Or of course with or without lens kit.

Edit: it's also worth mentioning that when using imperfect optics -- which is the case with many at long telephoto lengths, because not a lot of amateurs can afford professional primes -- APS-C means that you're only using the center 63% of the lens, which will be the part of the lens with the least problems.   That means you're squeezing 24 megapixels out of the center 63% of glass, rather than a 28 megapixels out of 100% of the glass.

If you are using the same telephoto lens on an APS-C camera and a full frame at the same distance, then your image of your bird (or whatever) will occupy the same physical space on the crop and FF sensors and be subject to exactly the same optical defects of the lens. There will be fewer pixels from the FF after you have cropped the image to the same size as APS-C of course, but the cropped image will be unaffected by the poorer edge effects of the lens as you have cropped out the edges.

You are absolutely correct.  But in reality, that's not how it works.  The same shot is often impossible from the same location, because on a FF, the subject would just be too small.  It's actually the entire premise of what I've been trying to say; perhaps I've been inarticulate.

Let's just say for the sake of argument that you have a 300mm EF mount prime (no zoom).  You mount that onto a crop sensor camera, and take a perfectly framed picture of your still subject at 50 yards; let's say, the subject takes 50% of the sensor height.

Now, you take the body off, and swap a full frame body, and take exactly the same picture.  You're right: the light hitting the sensor occupies exactly the same sensor area.  But the sensor area is 1.6x larger, meaning your subject, instead of being 50% of the sensor area, is only 31% of the sensor area.  Your know that real pixel output would make this too small to use.  It's not going to be perfectly framed anymore, because you wouldn't be happy with just taking a 62.5% crop area from the photo.  So what do you do?  Obviously, you move up closer to the subject.  My earlier point was that with wildlife, often, getting closer to the subject is not an option, so you'd need a longer focal length piece of glass or a higher resolution FF sensor to accomplish the same number of pixels of subject.

If you compare most current generation full frame with current generation crop sensor cameras, the full frame cameras don't have 1.6x the number of megapixels (ie density).  To fill your subject to the same number of pixels, you must move some distance closer, and which point, you are using more of the lens glass radius.

Of course, we can solve all this by simply using a FF camera with the same or greater sensor pixel density as the crop; but if you're comparing it against an 80D, that means going all the way to a 5DSR.

The best body for a lens would be the highest pixel density on the sensor that the glass supports built up to the size that the glass is designed for.  Since life is full of compromises, you need to choose between pixel density and sensor size, with the exception of 5DSR.

Went another round with my 200, and adjusted with tip from one thread here with the idea that both near and far dof limit should be equally oof, and I thought my 200 might be a little in front and indded it was. Went from +3 to +5 and now it's back to it's insanely sharp self. Brought my B1 today as well as it was near summer today (snow last week, lol).

It was way too bright for him to relax his face, but at least he was happy :D

1dx2+200 f2.0. iso 100, f2.0, 1/4000s. Profoto B1 in BD white camera right at full power, sun top left as edge.

Are they a legit company?

No, I would avoid them. If you want Grey Market try this http://www.ebay.com/itm/401201438202

EOS Bodies / Re: An Update on the Canon EOS 6D Mark II [CR3]
« Last post by CanonCams on Today at 12:47:28 PM »
Well. A late April early May release would  make sense from the registration information. It's usually around six months out, and it came out in December.

The only thing is the registration list that came out in December never mentioned the MK II.

http://www.canonrumors.com/upcoming-canon-product-certification-information/

DS126631
Canon EOS 77D or T7i
Wireless modules: ES202 (Wi-Fi) ยท WM500 (Bluetooth)

It was only in March that the MK II was mentioned.

http://www.canonrumors.com/canon-eos-6d-mark-ii-registered-with-certification-body/

DS126631 (Canon EOS 6D Mark II)
Digital single-lens reflex camera
Wi-Fi ยท Bluetooth installed
Equipped with latest wireless module ES202

and now again:

http://www.canonrumors.com/eos-6d-mark-ii-eos-rebel-sl2-show-up-for-certification-again/

so this has been showing up since December now.

I could see this points to a May / June release date IMO.

Then the announcement should be in April.  As they generally announce a month or so ahead of release.

Has anyone had any experience with Abe's of Maine? Are they a legit company? They have the 5D MK IV w/ 24 - 105 f/4 IS L II lens for about $600 off.

Thoughts?
