Testing my Kenko 1.4X with my 100-400L......RDU Int'l Airport

I have a 1Dmk3 (1.3 crop) and a 100-400L, but lately I've been needing more reach. I've developed an interest in capturing raptors, primarily eagles. I still do my favorites.........moto​cross, drag racing, air shows. But lately I've been chasing the elusive bald eagles around a local lake.

Regardless, I did some researching on this great forum a week or so ago......and found several people with a lot of luck with Kenko extenders. Low and behold, I found one locally on Craigslist. Specifically it is a Kenko MC4 AF 1.4X DGX. The price was about 1/3 of what it'd cost new, and it looks brand new! I will post a review in the equipment forum with some tests with/without the extension, in case anyone else was wondering. Most threads I found were tests with the 5Dmk2 and the 7D, so maybe it'll help someone else out down the road. This is already a long message, but as far as AF goes......it is definitely slower, but it is very managable so far. The real test will be when I go to a MX race or find some raptors in flight.

Forgive me for using Facebook as a host, but I am currently at work. If I remember, I will host them on my server Friday. Obviously Facebook compresses photos.....but obviously some clarity is lost with the extension. With good enough lighting though, there is barely a difference at all. With my 1D the 100-400L shoots at f8.

Like your flickr shoots; but none of those from facebook as above, maybe the Kenko combo didn't do any good.
Thanks for sharing.

The "flames" in photo 4 is the hot jet exhaust creating a heat haze that is distorting the air and the background behind.

You can see it in photo 2 as well. If you look at the runway/taxiway at the top of photo 1 you can see natural heat haze.

i like 4 and 6 best

Really like #6

I will go out this weekend to get some shots in full sun, instead of when its late/dark. The few shots I got that were decent had good natural lighting. I'll just need to be conscious that I need even more light than before with the dust pump. Thanks.

I never even paid attention to there being a red/orange tree right there. Now that you mention it, I look at it totally different. Figured someone would be able to explain it! thanks
