Am I about right here or missing something

600f4 mkII 1dxmkII = 21mp

400f4 DO mkII 5dsr = 50mp the image will be around 33% smaller but that still leaves 33mp making the image about 34% bigger than the 1dxmkII 600 combo

This is for Mps on the bird if taken from the same position

Have I got this about right ?
Rob.

I think the area of the sensor occupied by the bird will be 2.25x larger using the 600 (= 600/400^2).

Also bear in mind that if you crop on the 5DSR then you lose the light-gathering advantage of the full-frame sensor so you'd be looking at 7D2 levels of noise, etc.

Well, the 50mp sensor on the 5DS(R) would be the same of having a 19.5mp APS-C (crop sensor) camera if you crop it down to APS-C dimensions. So you can kind of view that 400mm lens as a 640mm "reach" by cropping it down to 19.5mp in the center.

I don't think the image is going to be 34% bigger. However, the pixel dimensions of the subject would be very, VERY similar.

Took the new body to its first E session last night.

This is close to a straight off file. I thought the camera did great. I dont have a lot to do If they select this for a print.

Also really nice to have 1/250 for a gate speed. 5D3 is 1/160 max. I can get it to 1/320 with the gate barely visible in Bright light....shade and I really have to look

2nd shot was on the water with a 3 stop ND filter. Really bright. But it handled the bright light and the flash killed the shadows. Worked well outside with a strobe

Not really sure why it would look much different than the combo using another body?

I'm afraid that the old lens like 135L can't perform with the newest body as well as with the older bodies. I am a 135L big fan, cheap but superb, although it is a great lens, if it can't perform as it should be, i will not spend some money on it. David arbogast found an odd bokeh from 5DSR + 35L II combo, i want to prevent something like this happen to me. This is apparently my first and my last photography tools purchase, maybe for next 5 years or longer. So i have to choose them very carefully, moving from thread to thread to see samples from the tools i want to buy. :-)

Here are the numbers;
400mm x 1.5 = 600mm
So multiply 1.5x1.5 = 2.25

The 5Ds 50MP divided by 2.25 = 22.22MP
(this number assumes a standard rectangular aspect ratio crop from the 400mm down to 600mm. I bet your 33MP is closer if we were talking about circular image sensors matching up to the circular image projected by a lens. )

So, with a 5Ds and 400mm you will get 22.22MP in the exact same field of view that a 1Dx2 will put 20MP (or any FF will put it's MP) with a 600mm mounted.


... I think ;)

You're thinking Nikon, me thinks. Canon is x1.6. :D

Thanks for the answers Looks like my next lens will be the 400do mkII to pair with my 5dsr as a lighter setup with no loss of reach .
Hopefully I wont need to crop too much .

You could always pick up a 2x TC (since I believe the 400 DO is f/4?) and then you'll be flying high with a 800mm lens.  :p:-P

Hockey and wedding photographer. Favourite camera / lens combos: a 1DX II with a Tamron 45 1.8 VC, an A7Rii with a Canon 24-70F2.8L II, and a 5DSR with a Tamron 85 1.8 VC. Every lens I own I strongly recommend [Canon (35Lii, 100L Macro, 24-70F2.8ii, 70-200F2.8ii, 100-400Lii), Tamron (45 1.8, 85 1.8), Sigma 24-105]. If there are better lenses out there let me know because I haven't found them.

The alternative is 'Landscape' it brings out the colours of nature better. Welcome to JPEG world in it's simplicity it brings fast results.

So after nearly two weeks of ownership i have my first Cfast card in the shape of a Transcend CFast 2.0 CFX650 128 GB Memory Card to play with so thats now either 4800 RAW images or 18560 Jpegs :-)

Oh Glorious 800mm. I need to commandeer some Kenko non-reporting 2x TC so I can stack it to my 2xiii and do something silly like astrophotography.

Rob.

You will only have the same reach if you crop the 5DSR to APS-C. This will get you roughly the same number of pixels on the subject (~20MP) but as you're capturing light over a smaller area you lose some of the signal-to-noise advantages of the full-frame sensor. (You're effectively shooting with a 7D2).

I also have a 5DSR and I do crop it when I need more reach but I reckon I lose a stop at high-ISO. (If I'm using the full-frame, it's good to ~ISO3200 but only ~ISO1600 when cropped to APS-C). The big advantage that the 5DSR has over an APS-C is that you can take the crop from anywhere in the frame.
