Unfortunately I didn't had time to test my 7D for wildlife photography yet. So last week I went for a week to Belgium to give it a try with the short-eared Owls. Last year I shot hundreds of images with my Canon 1DIIn the Sigma 500/4.5 EX HSM and the 1.4x or 1.7x konverter. I was curious to see if the 7D could hold up to my beloved 1DIIn.
So here are my first impressions.
Resolution and Noise
The one point I was most curious about was, if the Sigma 500/4.5 EX HSM (with konverters) could deliver enough resolution for the 18MP of the 7D.
After my first day of shooting Herons and Grey Partridge and viewing the results I was definitely relieved to see that I shouldn't have to worry:
Here is an image I shoot at ISO 5000 and a 100% Crop (click on the image to see the full version)
100% Crop
Canon 7D - Sigma 500/4.5 EX HSM + Kenko 1.4x TC - f8 - 1/1000s - ISO5000 - Window MountI was quite impressed by the resolution at ISO5000. If I see some of my images which I shoot at ISO1600 with my 1DIIn than the 7D is a good step forwards.
I also made some images ath different ISO settings and put the 100% Crops togehter into 1 image:
The images were processed with Aperture 3 and no Noise Reduction was applied.

Light conditions were not the best during the week I was in Belgium. It was grey the whole day with no sun. So it was a difficult situation for the AF and a good one to test the AF performance under difficult light situations for me.
With the modified Kenko 1.4x konverter the AF worked very good. Just as I was used to with my 1DIIn. In One Shot Mode the AF locked quickly on my subject. I also tried the Soligor 1.7x Konverter, which used quite often with my 1DIIn. Under this light conditions the 7D had quite some problems to lock focus on the subject and AF was not really a pleasure to use. I will have to test the 1.7x konverter with sunlight to see if performs better then, but under grey conditions it didn't work well for me.
I am very happy with the Kenko 1.4x Konverter and the AF performance in One Shot Mode. I didn't really get a chance to make test in AIServo Mode. I hope that I will get some chances in the near future.
Here are some more images from that week:
I hope that I will be able to shoot some wildlife images with my 7D in the next months.
