Picture taken with my A* 300mm f2.8 (hand held) K10D
This picture is great because the bird is going to build his nest with this moss.

Hi Marcus
glad to see you here; the web site that allow to track the parcel tells that the lens is at the Singapore customs; I hope they will not keep it too long.
Here is a good example that one can expect from this lens - here stopped down at f4.5; despite the very hard light conditions color rendering and contrast is excellent. Wide open it is prone to blue fringing anyway (blue halo around harsh light transitions for subjects slightly out of focus)
Nice and sharp subject of the bird, considering the bright hard background.. Probably I would insert a polarising filter for harsh backlights as according to the other thread .....Thanks for posting Jean phillipe.

those are the 100% crops anyhow, 550x600 from 3872x2592. I'm seeing that while they have higher contrast as the f goes higher, howver I feel that there is a similar detail being resolved, any opinion. Feel free to argue this ^^

Also, I have absolutely no idea why I am now seeing that not having the filter is improving the sharpness? even at f8?
Both images with and without filter are almost identical to my eyes. Yes the lower one without filter seems better contrast and sharpness. IMHO. Thanks again for sharing.

Hi Marcus
there are several arguments that prevent using a pl filter in this case :
first the contra light comes from a clloudy sky and in these conditions light is not polarized so filter may have no effect
second the 49 mm drop in filter in not easy to rotate !
third the bird is constantly moving so no time left to adjust the pl filter
I would better have used flash to fill in the contra light - and used raw because jpeg from this old IstD is less than average.
Anyway the picture is not technically very good, I wanted only to show the resistance to flare and CA, a lot of lenses would have produced a flat, poor contrasted image in this situation. It is also possible to have an idea of the resolution - albeit this is only a 6 Mpix camera.
Cheers

Any comments on the eyes for me ?

@ Goubejp: Would a 49mm circular pol be suitable for this use?
