| p.1 #7 · Assessing used 300 f/4 IS, what to watch for? Pictures with 1.4 please... |
Hi Cam, I've had my 300 for two yrs, used it with a gripped 40D and really like it; but I've no big glass to compare it to; no 400/500L, etc in my kit. Bare it is a great lens, very hand-holdable, well balanced and I find it's sharpness and contrast to be wonderful.
I've used both the 1.4x T/C II and III, and find the III to be just a bit sharper at the edges; AF response is the same with both T/Cs...sloooower I use center point single shot AF. Mounted on and EOS-3 film body there is more edge sharpness with the III as expected given the FF image surface. I've not tested with a 2x yet.
The 300's IS is not as fast as the 70-200 f4 L IS, and is a tad louder as well, older IS designs/lenses tend to be that way
Most of my subject matter is not action; some surfing, racing and an occasional BIF, that said, the 300 with a single or set of extension tubes is IMO a killer combo. Close ups of flowers, their bits-n-pieces look great. Many a garden has had the 100L and the 300 shooting it's bounty.
For me the 300 f4L IS fits perfect, budget, reach, sharpness, fun factor
I don't have any images to post ATM, I'm about to rebuild my laptop, move to Win7Pro, more memory/drive space, upgrade to LR5. So my archive is off line for a bit. When things are, including me, up and running I'll post a few shots from the 40D, and will follow-up when the 7D gets in the game.
I've one shot uploaded here on FM using the 40D/300, the link is below, it's not the best shot for checking sharpness, the sparrow picture was about 40-45 ft. away on a very cold/overcast day.
