Having an EOS 5D MkIII, the 100-400 II and the Extender 1.4x.
Would the EOS 7D MkII bring a tangible improvement for capturing small pirching birds?
Thank you.

The 7D2 gives finer noise with less banding, and more subject detail, from the same distance, with the same f-stop, and with the same shutter speed and ISO.

Will the 7d2 lock/stay locked with birds heading towards the camera? My 5dmkiii has been hit/miss. I did move it to "case 2", which helped, but I'm sort of on the fence if I simply need more practice/luck, or if the 7d2 is going to yield more consistent results?

Thank you John. I read your answer carefully.
The question now focuses on the lens: Can the the lens set @400mm with the 1.4x extender deliver the required by a high definition sensor or will a FF sensor suffice?

I don't think that high-res sensors require anything. The sensor is there to serve the lens; the finer the resolution of the sensor, the closer it is to making a virtual analog capture, and the better it records the lens. TCs and smaller pixels both work towards recording what the lens is actually projecting, more accurately, with less artifact. It matters not a bit if that means that 100% pixel views on our low-res monitors look soft because of it.

The only drawbacks of TCs are that they can sometimes (but usually don't) cause electrical problems that might compromise the image stabilizer, they may lose contrast (micro and/or global) if they are inferior grade, they might interfere with AF, darken the viewfinder, and they might make your composition too tight, if you're too close (it may take too long to remove a TC if you can't or don't want to step back from the subject).

The only downside of higher pixel density is that sometimes (but not always) the biggest pixels on the biggest sensors have the least read noise at high ISOs, per unit of sensor area. They are universally btter at low ISOs, and often at medium ISOs, noise-wise per unit of sensor area. The 7D2 is only about 1/4 to 1/3 stop worse than the 1Dx and Nikon D4s per unit of sensor area in measured high-ISO noise, and is as good or better than most other big-pixel sensors (the 7D2 has one of the best high ISO noise characters of any camera; easy to clean and it cleans up quickly with reductons in displayed image size).

That said, I can get fairly pixel-sharp results (sharp enough that USM works easily without sharpening noise too much) with the original 100-400 with a 7D2 and a 1.4x, so I'm sure the new 100-400 is even sharper, especially wide open. Often the actual practical limit is due to the stability of the camera and subject, and AF error, not the lens sharpness. Reports I've read here and on DPReview suggest that the new 100-400 + 1.4x works like a good 560mm f/8 lens optically, and AF, while not quite as snappy as at f/5.6, works well in the center point.

I added the 100-400ii for the 5Diii platform. I'm pleased now-

I occasionally shoot motorsports. I tried my new 100-400 II at the autocross course today, I am very pleased! My ratio of keepers is decidedly up! A couple of sample images!

Im really happy with this lens and on a 7dmkII it has lots of reach for a lightish set up ideal for when your walking around .

Rob, you remind me that I have not yet posted my official POTN duck photo for a new lens and camera.

So here's mine for the 7DmkII+100-400mkII combo ([edit]oh, I should note with 1.4x extender III[/edit]):

It ain't much but at least it's (a) a duck; and (b) taken in reasonably difficult circumstances (most especially the near-complete absence of actual ducks near me until this morning). I hope I'm now "official".

Thanks Jeff. The absence of ducks was starting to bother me!

Hi

Thanks for sharing a 5D3 image (same body:) ) a lovely capture first flap after takeoff - could you please say what the exif details are plus any feedback about how close were you, I surmise this was at 400mm max zoom, and how much if any it is a crop?

TIA :)


That was a great meal ~ you must have a good set of pans :p

^Thanks BoxBrownie.
If you click the Flickr link all EXIF is there.
Twenty feet or slightly less, honestly a bit too close, Barred's can do damage and his only exit point was
my way. He veered off quickly though.
30 percent crop my memory says and yes full zoom at 400mm.
Honestly once I reviewed the pics I was super pleased with this one.

Thanks for the extra insight :)

Looking at your Flickr and sorry if I missed it there or hereabouts but have you tried the 5D3 with the 100-400mm MkII + the x1.4 MkIII TC ??? If so how did you find that combo and the quality of the images from it???
