Default K-5 & Sigma 17-50 f/2.8

Hi all,

A few results from an organ concert I attended yesterday.

K-5 and Sigma 17-50mm f/2.8 OS HSM + Hoya uv filter HD

I got the lens for my upcoming hiking holiday, looking for a lens with specs that would do justice to the K-5. After coming across a review about it on photozone.de, it didn't take long to decide. I'm very pleased with the results; what a sharpness!
It does come with some vignetting at the wide end & f/2.8 (see below) and it's so big (77mm threads) it interferes with the on-cam flash, but it's just a little.

1 - It ranks amongst the largest of church organs in the Netherlands

2 - the spotlights on the organ were already out; brightened the scene some in PS -forgot vignetting removal

3 - same scene with vignetting removal (in PS camera raw)
Happy Shooting! GB

Very nice shots! That organ is beautiful.

If Sigma were to release a weather resistant version of this lens I'd buy it in a heart-beat. Pictures like this make it really hard for me to put cash down on the DA*16-50 but the main thing I want is weather sealing (I have other options in this range). Pictures like this definitely do NOT help buy what I really need.

I can always hope that Sigma will cooperate, can't I?

The organ is amazing! And the detail you have shown indicates that the lens is tack sharp.

i agree that this weather proofed would be nice but dont think it would be much cheaper than the da* and (fingers crossed) have had no problems with the sdm and been very pleased with how sharp the lens is

my only complaint is the vignetting at wide apertures/ short forcal lengths but its really not an issue as its so easily corrected in photoshop
