This is part II of my experience with the Canon 5D Mark III.
I mentioned that in part I that its focusing system was great even in
low light environment. I decided to test it again in BIF photography.
My test subjects included sea gulls and Forster's Terns.
I also brought along my beloved 1DIV for this test. The lenses used were
70-200 mm f/2.8L IS II and a teleconverter 2XIII. For subjects moving
in erratic direction, especially the Forster's Tern, the 5DIII was able
to focus, lock in, and track very quickly. I got quite a few
sharp images. Honestly, I started BIF photography since January 2012 and I
only take pictures on weekends. So my BIF photographic skill is still developing.
It is fine, but not great. Given that, I still managed to get 50 - 60% sharp images,
compared to 40 - 50% with the 1DIV.
I do think that the 5DIII was a bit faster in focusing than the 1DIV. However, the shutter
sensitivity (shutter response time) was better with the 1DIV though. Also, the 1DIV captured
more images due to its 10 fps capability.
In terms of noise performance, I think both are quite close. Please note that
I only use raw mode. I guess the 5DIII's noise performance with jpeg should be very good.
With raw, I do notice that the 5DIII is more detailed and roughly 1/2 to 1 stop better than the
5DII in high ISO like 3200 and above.
Overall, the 5DIII is a great all around camera. It can do both landscape/portrait and action.
With only 6 fps, it managed to get some great BIF photos. Please see a sample in the link below.
Some folks keep saying the 5DIII is overly priced. I do think that its improved auto focus and 6 fps
in full frame are worth the admission price and also the upgrade from the 5DII. The 5DIII is awesome.
Stay tuned for more updates and experience with the 5DIII.
