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

Hi,

This morning when I dressed for running with my Sunday morning running group I put on a shirt that I got at a trail race last year. On the shirt is written "Run With the Beavers". Some of the other runners commented on the shirt, so I gave a little information about the race.

When I got home, I decided to bushwhack into a beaver pond a short way into the White Mountain National Forest from my house. I saw a few young ducks and then this wild flower that I don't know.

Great Shots!

My Supermoon pics - cropped and sharpened on the first one, high humidity made it a little dull, second one is just a crop:

Congratulations Jon, I know how you are feeling! I also suspect that it'll be a long time before you've time for your normal photography again!

Here is my Supermoon contribution...

Anyone in here use this lens with kenko 1.4x I am interested to hear from experienced and any issue might caused. Also the af behaviour. I would really appreciated if you can share some thoughts..

Thanks

I've read good reviews from those with FF, and even the 7D. Yes there will be more focus hunting than if you were not using the Kenko.

Good chance my personal copy was not up to par - I did not have a good experience with my 60D at all... too much focus hunting...

Hi,

My experience with the current top of the line Kenko 1.4 converter on my 60D matches Wills. However, I tried two converter copies. I was not pleased with the auto focus lock up. Also I was not satisfied with the image quality when using either manual or autofocus with and without a tripod.

I also tried one of the converters on a T3I. In that case center auto focus seemed to lock up better than with the 60d but the image quality was still poor. I returned both copies of the converter. I would have kept the converter if I could extend reach with fair to good image quality using either manual or autofocus but couldn't achieve it.

hmm...are there no good TC choices for this lens? Since Canon doesn't make a TC that works for the 70-300L, I'm wondering if anyone does.

I'm a little new at this stuff so I'm not sure that someone else could not have made it work. It's just that I couldn't.

Before I tried to make it work for me, I read about the issues that Will and others had with using the Kenko 1.4 and 70-300L together on crop cameras but thought maybe my goals were lower.

Since I believed there was a high probability that I wouldn't be able to get it work, I made sure that I purchased from a company (B and H) with a very good return policy. I've another purchase that I want to make soon so I'll reward B and H by purchasing from them.

I 'think' my poor 'hunting' experience with the Kenko 1.4 Pro was rare as for the 60D - but I have not seen many user reviews either... the 7D - although a crop sensor - at least has a microadjust focus feature...

Jack, that last beaver picture is brilliant. Colours and detail proving the 60d can hold its own. I keep going back for another look!

Great close up shots Weja. That beaver shot's amazing Jack. I love the 4 eared monster Monkey...very effective!

My experience with the Kenko 1.4 is mixed. The AF is way better than I thought it would be but having said that I thought it might not AF at all. Given good contrast it's not bad at all. I've successfully managed to track BIF (but big ones). I've recently changed to using back button focussing and that probably helps because in low contrast situations it can hunt a lot.

I've no real complaints about the resolution but I do have to change the micro focus a whole heap when I put the Kenko on...and then again when I take it off. I risk a whole session of OOF shots if I forget to do this.

F8 as a minimum at full extension reduces the available shuter speeds considerably too.

For me these negatives are a small price to pay for the extra reach and relative convenience.
