K-5 & Sigma lenses: is everything fine?

garethwebber · 10-22-2010, 09:58 AM

Hi

Do any of you new K-5 owners have a sigma lens collection? Are they all working OK, just a concern given the AF changes and sigma reverse engineering the mount. Most interested in 50-150 HSM2.

My other lenses are screw-drive so would imagine would have less issue (if indeed this is one at all which I am hoping not as I am busy saving)

My sigma lens list: 30, 50-150HSM, 70 Macro, 100-300.

Thanks

Gareth

I've briefly tested my Sigma 18-250 on my K-5, and both HSM and OS work perfectly fine. I didn't really notice any speed differences with it on my K-x, but HSM was pretty fast already.

Great! Thanks for that: You have just annoyed my bank manager.

Tried it with my 10-20 and it seems to work well.

I have that lens and 2 K20s and I love it. I want the K5 to use it with for the high ISO benefit. My only hesitation is that from the samples I've seen, the K5 3200 noise looks much like the ISO 400 noise on the K20. That would be like having an 18-250 f1.2-2.4 lens on the K20. I'm afraid my other lenses may never see the light of day again.
