Turning money into pleasure

The 300mm f4 is certainly better, but I chose this one for its compactness and versatility.
Working in rotation (in Gabon for the moment), I need to find a compromise between size and quality to travel "light" while having quality photos.
It is the ideal companion in my opinion. The 70-300mm DO is lighter and more compact, but for the same price, no hesitation, I choose the 70-3000 L.

The sharpness, the colors, the colors are amazing.
Autofocus is fast enough, but much depends on light condition obviously.
Overall, it is formidable, on a 7D with reduced central collimator, flying insects are fixed.
On the 6D is less good, he hesitates more. I'm usually in manual.
The stabilistation is effective, especially coupled with the rise of ISO 6D. Little noisy, except for the wearer because the vibrations feel, and it is quite handy to know when it turns or stops.

I am more pleased to have acquired this "pebbles" rare sensation finally; I rarely attaches me to an object, but this one is my favorite, with the MP-E and my volvo ...
