Neuro... have you stacked the 1.4 + 2x on the 70-200mkii ?
No, I haven't tried that (yet). I can, if there's interest. I've been considering doing a comparison set between 70-200 II with single and stacked TCs, 100-400mm with single TCs, and then cropping everything to the same FoV (equivalent to the longest, i.e. 100-400 + 2x), in decent light (unlike the one time I tried the 100-400+2x), and seeing which gives the best results...
I can hear it now!
"And with this 35 megapixel compact body you only have to point it in the general direction of the target and you can later crop down to a 18 megapixel image, just like the 1DX body!!"
About 6 years ago, the air conditioning on the roof of the building I was working in had a problem with a bearing. It produced a very high pitch noise that I could hear and gave me a headache but nobody else in the office could (I was the youngest...)
Dare I ask what your thoughts are on 96kHz audio? I've got a few SACDs and the appropriate equipment to deliver 192/96 to the amp and out of the speakers...
Exactly! I suspect that if a 5DX were to have a foveon style sensor with colours arranaged vertically rather than in a horizontal 2x2, we'd find companies doing the Sigma thing and calling a camera with 15MP a 45MP camera.
One of the problems with very tiny photosites is the narrow angle of view of each photosite. Those toward the outer edges have a real issue trying to get light due to the angle of the light rays.
If the maximum resolving power of the current L-series lenses is around 45MP for full-frame 35mm cameras then when the MP count exceeds 90MP is when we have too many MP. Why 90? Because at that point we've got enough resolution to properly sample the light and give clear definition to the 45MP worth of detail.
Kind of like how the music on CDs is sampled at 44khz, whereas the human can't hear much over 22k. The higher sampling gives better definition to what can be heard.
They are $2374 today, so you got good deals.
Thanks for the tests! I will reiterate that using autofocus is not the best way to test lens sharpness, since you're not testing just the lens, but how well the lens is matched to the camera's AF. Also, an angled ruler is a challenging target for the AF system. So, while I appreciate the efforts, and acknowledge this test has meaning for your camera+lenses, I don't believe the results can be generalized to these lenses as a group, due to the confound of using AF (with no ability to calibrate it).
