Canon hand held at 1280mm .... - DPChallenge Forums

I thought I would see what I could do with my 100-400mm IS lens with a 2X II Extender hand held - at 1/125 of a second at full Zoom ... This is the full shot at about 65' with no cropping done. .. I am quite amazed ... You can get the full detail on the shot in the description on the photo ...
I hope someone who was wondering what it can do ... BTW - only basic editing was done ..

a 2x TC only makes the lens a 200-800mm and since you loose 2 full stops it becomes a F/9-11.
The crop factor (1.6x on the 20D) only gives you the same FOV as a 1280mm lens but not the magnification.

Incredible that you managed to handhold such a long and slow lens.
Good luck

Stupid Question Alert..
Does the "IS" still work with the 2x on?

Nice shoot. Unbelivable that it is hand held and at 1/125

IS will still work on the 2X II but not the 2X - focus becomes manual on both

AF works for me with the 2X II attached. I don't like the quality of what I get, but the AF works fine. I don't know how it will work with the 100-400mm.

It will work with faster zoom lenses like the 200 1.8 l and probably others - but not on the 100-400 L IS - there is not enough light .. apparently..

In order for AF to work with (any) 2x converter, the effective aperture must be f/8 or faster (meaning an f/4 or faster lens) on 1-series bodies, and f/5.6 or faster (f/2.8 or faster lens) on non-1-series bodies.

Shame is, you could have shot that at an extra stop judging by the fire in the sky!

1/250s would have been even better...but that's a steady hand you got there.

I did get a shot in at 1/320 but I was further away and it is only 1 on the doves

Is it clearer?

The 1/320 shot is definitely clearer. No surprise there :)

but still quite overexposed....any tack-sharp shots at 1/1000?

I haven't fooled around with this set up very much - so since it was nice out I thought I would quickly just see what it can do - some of that over exposure in this shot is my fault - when I processed it from RAW - it wasn't not nearly that over exposed on the original... - I am thinking it would have to be very bright for 1/1000 or I would definitley need to go to at least ISO 400 .... Just come over sometime - thatcloudthere and you can give it a go if you'd like .... When ever you are in London..

the subject in the second shot isn't overexposed; if he exposes for the sky, the subject will be VERY dark.

On the Canon 100-400 lens - the 1.4 teleconverter will work with autofocus with just the center focus spot selected. You do still lose light. Using the 2X teleconverter - the autofocus does NOT work because there is not enough light. While manual focus will work OK when you have a lot of light and your subject is relatively close (filling the frame), I haven't had good luck most of the time with manual focus. On the Mark II you have a choice of interchangeable focusing frames inside the camera. That should make manual focus much more accurate. I don't have the bucks though for that upgrade.

I would love to try a 1.4X II - Do you know how accurate the focus is?

The closer you are to a subject and the better the lighting will give you better focus, obviously. You also have some difficulty framing the perfect shot, since your subject is going to be pretty closely centered for focusing. It also takes longer for it to focus . . . so shooting a moving object isn't practical.

My best luck with the teleconverters has been in my backyard pond, where the egrets and herons were fairly close, and the teleconverter allowed me to fill the frame with them. I have also shot small mammals at Joshua Tree and an osprey near the Pacific Ocean, but they were further away. Because of their distance, the photos needed cropping and the details just weren't there. The photos are just not as clear as I would like for competition quality. I've also tried it with perched hawks - and I'm never quite pleased with the results.

I haven't tried the teleconverters with fixed lenses, but I've heard they work much better. I'm getting ready to get the Sigma 300-800. Supposedly I can use my teleconverters with that - so I guess I'll know in a couple of weeks whether that is better. But at least my lens itself will get me in closer to those raptors.

Just so you know - I shoot with the Canon 10D - not the Mark II.

The other factor on image quality with the teleconverters- you are adding more glass - which can and usually does impact the quality as well as the light.

I'd really appreciate hearing your opinion of that 300-800 after you've had a chance to break it in.
