It is outstanding lens, sharp enough wide open, perfect in direct sunlight, here are some samples with Pentax K-3:

Well I finally managed to buy a Sigma 100-300 f4, after several months of trying.
Here is a couple of shots.
First is 300 wide open, the second is wide open with the sigma 1.4 tele converter. I think I am going to be happy
shooting my girls playing soccer this summer !!! When ever the snow decides to leave !

Nice. AF works also with the 1.4 Sigma TC in?

Sure. It's just screw drive AF and the effective aperture is f/5.6, so no problem for the camera.

Then SIGMA 100-300 f/4 and his TC are a terrific combo!

Hi Andrea K
I didn't notice any difference with the converter on.
Did notice the weight of this lens ! The monopod will be
out with me and this lens next time !!

From the Adelaide University flute symposium, Michael Cox - Principal flute of the BBC orchestra:

Pentax K5IIs - Sigma 100-300mm f/4 APO EX DG @ 220mm 1/60th f/5.6 ISO 3200

With steady hands, the Sigma 100-300mm f/4 truly excels at concert photography.

I just picked up a really nice Sig 100-300 F4 from a forum member (thanks Sergy!) Literally have had less than 24 hours so haven't played too much yet, but based on what I have shot I really like this lens. Its heavy but barely hand holdable..Thats how these shots were done. It was a pretty cloudy and windy day at the shore and I really should have used a tripod, but if it shoots this good in adverse conditions, I'm going to love it in better ones.

K3 works well with this lens though I did end up bumping up the AF +4

-al

pp in darktable with slight sharpening, slight saturation increase, some are cropped. minimal processing for most.

Good to see that you are already having fun with it

Fantastic lens.

Too bad Sigma threw the towel in terms of supporting K-mount. However, this particular lens had been discontinued a long time ago anyhow.
