with the lenses that you have, its surprising you haven't gone full frame already. I suppose the real question is do YOU feel the 1Dx is overkill for an amateur? Obviously the best camera in the Canon range, so would you be able to make do with the 5D mk3 instead?..... there are a lot of people who would love to have this dilemma!!!!
I specifically did not buy any EF-S lenses because I knew I wanted to go FF some day. And because I realized that L-lenses are a better deal in the end. And of course now (with the fisheye and the 16-35) I am frustrated with the crop sensor.
And yes, I am fully aware that I am spoiled to have this dilemma...
@docsmith & emag: Of course my wife is a keeper... And she also knows that she needs to let me get a new toy occasionally
But I have already bought so many things that she absolutely needed that she figured it out by now. Now she only laughs at me when I mention a big lens...
@dstppy: yes, high-ISO on the 7D really is terrible (as has been mentioned often enough). I had AF problems when shooting BIF and kite-surfers on a lake with a forest behind them - I was quite surprised, but for some reason the system did not manage to follow. Granted, kite-surfers in air are so slow that you can pick a single AF point and follow by hand, but I wanted to test the camera and it failed (this was with a rented 300/2.8, btw). With the birds it was similar - when the focus was on the bird it was really on it, and the image was sharp. But with the fast motion the bird was lost all to often. I don't know if others have made similar experiences or if I did something wrong there, but it was quite frustrating.
In any case, thanks all for your answers. The underlying issue is, of course, that I am a sucker for tech-stuff. And the 1DX just fascinates me. Mostly the super-high ISO, the low-light focusing ability, and the high frame-rate. I am never really in a situation where I would absolutely need 12 fps, let alone 14 - after all, I don't sell the photos anyway, so if I miss THE moment it is never all that much of a problem. Usually my anticipation is enough to get a shot that I am somewhat happy with. For everything else I guess the 5Diii is on par with the 1DX (OK, I also don't need the better water-resistance and added ruggedness).
Another advantage of the 5Diii would of course be that I could then afford to keep the 7D and have both FF and crop. If I would get the 1DX I would probably sell the 7D. I have also been considering getting the 300/2.8, selling the 7D and buying a used 350D instead
