Canon EF 70-300mm f/4-5.6L IS USM

Nice captures Jack - always magical coming across deer

Thanks! The deer just seemed so happy for the beginning of a beautiful day. The kayaking part of the day on Winni was nice but I could not find the eagles that I usually see. Since the baby eagle fell from the nest, they are no longer in the feeding cycle. That part I find sad, but still I enjoyed my paddle.

Love the bad hair day Jack!

Here's a couple more with the Kenko 1.4.

In good light it's pretty quick to focus on the 7D and I'd say it's not too bad for BIF but in lower light and with lower contrast it does tend to hunt a bit.

Ni captures ~

my experience with the Kenko 1.4 was quite poor with my 60D and I returned it.

That said, the one good shot I got as a keeper was of the moon and this lens - great detail...

I'll eventually buy another Kenko when I eventually get a new body like the 70D ot 7D II

Will, one thing that I found was that the Kenko paired with the 70-300 back focussed a whole heap such that many of my initial shots were significantly OOF.

My 70-300 needs about a +6 adjustment (it front focuses) at the long end and much less at the wide end...I've settled on giving it a +4. With the Kenko attached I need an adjustment of about -10.

Anyway, at the long end that's a difference of -16 and the camera only does a +/- 20 so it's enough to be really noticeable, I'd say it's severe back focus and something you couldn't live with without micro focus adjustment. Anything over about 3 really bugs me and can result in nicely focussed nostrils instead of eyes!

When I was testing it I took some pics of ducks on a log about 15-20m away and the only thing in focus was a strip of water well behind the action. l pop up an example of how much it was back focussing when I get to my PC.

Ok...some pretty crappy photos...I was just trying to check out the focus...honest!

Just to show how insane the sharpness is on the 70-300L, this is at 300mm wide open from about 6-7 feet away and then cropped in to about 100% on the eye...I really love this lens...

I really love this lens a lot.
Sharp, very good stabilizer and good for close photography like this dragonfly

Amazing.
Love the flower detail too

Another example of how close you can come to the bigger insects.
You keep instead of a real macro lens your distance and the fellow
will not fly away so quick.

Weja - beautiful shots of the dragon and bird.

Thank you Immaculens en Bobobird for the kind words.
All pictures taken handhold, with the incredible good stabilizer on this lens.
