How's this for 400mm? (1 Viewer)

Overread

Hunting birds with a canon
Ok warning really boring dull shots approaching! Sadly since getting the new lens I've not had a chance to get out in good light. However even though these are less than ideal I'd like to hear what people think on the optical quality:

All taken with Canon 400D, Canon 70-200mm f2.8 IS L M2 + Canon 2*teleconverter.

f5.6, ISO 100, 1/320sec

Abusing the IS at the slower speeds, though with a static subject and IS I hoped that I was able to counter enough of the motion to let me keep the ISO low. In practice I suspect ISO 200 will be my more normal working ISO to allow a bit more speed without too much quality loss.
Also for users of the 100-400mm I'd be interested to hear how these results stand up to it.

A few more dull test shots can be seen here:

note the vignetting in the top right as seen on some shots is not a lens nor camera property, but the fact that the window was small and part of the frame crept into the shots.
 
We are talking here a lens over £2000 + x2 TC I think it would be better if we had some dragonfly's butterfly's or birds to look at the quality its produces, Chimneys type's don't do it for me, but I bet its a nice lens down at the 200 end. Are you just testing it or have you bought one ?
 
Bought one - or rather upgraded to one having sold the original that I had and shifted up to the new version. Originally I wasn't going to do this at all since between 70-200mm and even with a 1.4TC the original was (and still is) a fantastic performer - however it was the improved 2*TC performance that I wanted - and having seen comparison shots that show it as being not far behind the 100-400mm at 400mm I thought it was well worth shifting to (esp as selling the old made up a lot of the cost for the new - if buying without selling I would not have spent £2k on this for 400mm but £1k on a 400mm f5.6, 100-400mm or 300mm f4 + 1.4TC.

Also I've now got a few more shots on my flickr that do have some nice birdies in them! Sadly I had to put the ISO up on the longer shots which didn't help things; sadly I think I need to look at getting a better beamer for my flash at at 400mm ranges its just not got the power to really work well enough.

This is a massive step up from the original lens and this teleconverter!
 
Its looking Good overread, nice images, I suppose they could do with a bit a sharpening, but thats just me, like me sharpening bit. Well more than a bit :eek!:

EDIT: BTW I went back out with Sigma 150mm after having been out several times with the New Canon 100mm HIS, I had thoughts about the selling the Sigma 150mm but they soon went away, will keep both lens.

Aye the shots would benefit from some sharpening and contrast adjustments - the above were out of camera and just through white balance and some minor exposure adjustments in RAW so I didn't in any way start to really pull the best out of them.


Also I'm glad and interested to read that both the 100mm and 150mm can find a place in your macro setup! Certainly I did wonder if the 150mm could stand up to the 100mm and its versatile IS - not a bad lens by any means but it was the wonder of if the IS would simply make the 100mm the more reached for lens than the 150mm.
