Thanks everybodyfor your replies.

Will, I know this is something I would finaly have to decide by my self.
I just wanted you all, who are far more experienced than me, to tell why would choose one or the other lens, so that can help me to make up my mind.

I'm aware it's something personal, and a metter of taste, the thing is that I'm not experienced enough to tell what I would like more(if you know what I mean)
Thanks for the patience anyway.

And Phil, Thanks foryour post was great and very helpfull, Thanks a lot

I guess I'd be missing more the extra range than the speed so far...

Hi everybody, first of all I'd like to thank everybody who has replied to my last Thread (about softness in k10d JPEGs). You helped me a lot and finally, I'm going for the k10d.

After some search I'm between two lenses
Tamron 18-250 3.6 and the Sigma 17-70 2.8.
I know the advantages and weaknesses of each one.

But how do you compare each other in terms on IQ
I guess (only guess) that the less extreme range and bigger aperture of the sigma should mean sharper images (I might be talking nonsense).
If so, do you think that this advantage the sigma might have in this aspect, justifies it’s shorter range?


I’d be doing mostly outdoors, lots of pictures in the Water (I’m a Fly fishing Guide) with a polarizing filter. Sigma rotates when focusing, but the polarizer would make the tamron even slower.
To make some of the kind of shots I want (freeze a fish jumping in the air) I’d need to shoot at 1/500. With a polarizer and in the sunlight do I need the 2.8 aperture?

It’s being really hard for me to make this choice range vs speed.

I hope you can help me to get out of this hole I’m into

Thanks

K10D softness in JPEG

Is it possible to compare the k10d and the D200 raw-JPEG converter by taking an image in raw for example in a K10D, uploading that image to D200 and then JPEG it in booth cameras and see what happens?
has anybody tried to do that?

K10D softness in JPEG

I'about to buy my K10D but there's an issue that's making me hesitate.
I'm concerned, about the in camera RAW to jpeg convertion. According to dpreview and others:
...JPEG straight from the camera, if anything the JPEG has a slight lead on very fine detail . Both the JPEG and Photo Laboratory however suffer from a softening of edge detail which can be seen quite clearly when compared to the output from Adobe Camera RAW...

I know that this software might have it's advantages, but still I'd like to know if there's a way we can modify this. The question is, does the K10D offer a alternative JPEG-RAW converter option wich can produce crispier images?

thanks, I'm looking forward for your reply
