Expensive great Tele

I am delighted to be one of the lucky ones who can call their own this great telephoto.
Anticipation, I am not a professional but a simple amateur, who is engaged in only three years with photography.

Since I have determined as considered many other read even after numerous reviews here back and forth whether to invest so much money, I think it is important to get it as much information as possible.
My experience so far is based on a Panasonic Lumix, the EOS 600D and the 7D currently.
Especially when it comes to animal and sports photography, the 7D was previously equipped with the Tamron AF 70-300mm 4-5.6 Di VC USD SP, the great images delivered and for an absolute top price!

If Strandspatziergang I met the other day a photographer who had 100-400 on his camera. He proudly presented me with his shots, which were, despite additional converter 1A. Since you can not go wrong at AMAZON, I decided to invest the money and to order the Tele.

The next day already rang at 10:00 clock the package delivery company and I was looking forward to the first photo with my new lens. The first pictures were made quickly, and then came the moment of truth.
Open the memory card into the PC, image editing program and then ... wow, razor sharp, great colors ... madness!
Clear what I expected for my money, but the image quality has exceeded my expectations by far.
A fortiori, I marveled not bad then when I saw the images with ISO 800 were added and with a scarcely perceptible noise.

Have me in spite of bad weather may convince qualitatively the images next day on the sports field.

Of course, now made almost 1,000 images and a few rivets are, but as I already was able to discover what this lens it has is the culprit for this probably the man behind the camera.

My Conclusion: If a sparrow razor sharp 300 meters away and will scan at 100% view is perhaps at this lens have no joy, for everything else I can advise everyone to this investment. Mistake one makes with the purchase certainly not!

In conjunction with the 7D way, I have found that is the quality of image size M best.
