SMC-F* 250-600mm @ 600mm + crop

I wanted to test the SMC-F* 250-600mm and hoped to get some decent photos, but shortly after this shot it began hailing, then raining, and I got soaking wet... I hate photographing in the heart of winter

Anyway, here's the full shot:




And a 100% crop from the Great Tit (what's in a name) alone:




Your verdict please?

do you have a 100% crop of the branches to the birds right (our right)?

edit: F-stop?

I can make another crop tonight, but here's another crop from the 1st photo (shot at F8, by the way):




And a completely different subject (600mm F8):

I like the bokeh but not the sharpness.

High ISO?

Yes, this was shot at ISO 1600 on my K-5.

In that case, it came out well, I think.

I imagine at base ISO (100?) it would be quite a bit sharper?

For a 600mm zoom at 1:1 I'd say that's pretty damned good!
The OOF regions look very nice btw(no blooming or CA here) but then again... there is no direct sunlight either

Based on what I'm seeing here., I'd love to own this lens!

I am surprised to see this much noise for an iso 1600 shot taken with the K-5. Did you boost expsoure in post processing?

I really love the images of those orange "berries" of some sort.....delicious rendering.

Isn't this a Blue Tit (Parus caeruleus) rather than a Great Tit (Parus major)?

No, I did not. I tweaked the levels somewhat, but not as much that you should call it "boosting". IMHO for an ISO 1600 shot there's really not much noise to speak about. We're speaking about a 100% crop here! Also, I think it's in line with DXOmark's "sports" ISO value, which is ISO 1162 for the K-5.

That's what I thought, thanks

Quite possible, I did not check the species against my birding guides. Thanks for the clarification!

I love the berries shot--the background absolutely melts!

I think you are right. The great tit, despite being a little larger, has a black cap not a blue one.

+1 for the bokeh on that excellent berries shot !

BTW - I always meant to ask you - what program do you use to border & title your shots, I really like the way it'd done.

I would need to question ISO 1600 and 1/125o shutter. I would have to assume this is a tripod shot, and would have opted for about 1/250 shutter but much lower ISO. In all seriousness the shot is not bad but not what I would want from this lens.

Maybe some of the lack of sharpness is due to the tripod in use.

I confirm this is a blue tit :

and here is a great tit :

both shots with a FA*600 f4 (another ultimate LBA)
Some technique is required to domecticate such monsters; use shutter speed always 1/250 or above, calibrate AF very carefully cause DOF is very, vey narrow; I re-focus every 3 shots usually: atmosphere diffusion is a real issue, and depend on weather conditions can ruin shots; you may expect additional expenses for a gitzo systematic tripod (aroudn 600 euros) and a ballhead (400 to 500 more euros)
Congrats for your new lens
