Hello all!

I don't know if I've posted in this section of Steve's forums at all... and lately I've been away (travelling for work) so haven't been active in ANY section actually!

But I bought a Canon 100-300mm lens for quite a decent price (well it fit my budget). I have taken a few shots with it so far and am quite happy. Here is a bird I took sitting on an old castle ruin earlier today.

What do you think? It's at 300mm f8, I'm quite happy with the sharpness, though I realise I should have applied unsharp mask at the end for websize photos, I had applied unsharp mark before resizing... silly me.

Anyway, please excuse my ignorance... I don't even know what this bird is.... I've still got to get used to the names of lots of native flora and fauna here in Romania... I was born half a world away in Australia, I'm still more familiar with marsupial names than European species!! :-)

Looking forward to your comments

Paul

hi Paul. that lens looks like it takes decent shots... nice and clear, at f8 anyway. the real test, of course, is how it does wide open. a lot of long zooms are great at f8 and above but get soft in the corners atf5.6... the only thing i'd critique on this one is that it seems a bit bright. no idea what the bird is, though!

Hi squirl,

Good to see you again, and thanks for your reply.

Indeed as you wrote the true test for a lens is to see what it's like at the corners wide open (and at maximum zoom in this case too).

So here are 3 examples (crops) of such (300mm @ f5.6 at or very near the corners). Sorry they aren't very special photos / crops, but it gives an idea of the lens' possibilities. First is of a window RIGHT at the corner (bottom right), second of my fiancee's hand (while rollerblading) near the bottom left, and third of a bird's wing at the left edge.

For the price I paid (about £200) I'm very happy with it. Of course I there are other better quality tele-zoom lenses out there, but for me it was important to have a quick autofocus, and the 100-300mm Canon has that with it's ring USM. And to get IS and higher quality I would have to pay at least double the amount. So I'm satisfied!

Paul

photo #3

Note these 3 last photos are 100% crops. At smaller apertures at maximum zoom I have to admit there is some mild chromic abberation (purple fringing) but I've noticed other lenses have this too and it doesn't seem too bad on the overall photos.
