New Lens Arrives

Got home today to find my neighbour had taken delivery of my Sigma
10-20mm.
I had to make him a cup of tea to get it off him though!
The trouble is it's too dark to try it out, I'll have to wait till tomorrow.
It's quite bulky beast and looks to very well put together, so I'm looking forward to years of use.

Ditto!

Terribly excited about it. A big thank you goes to SRS Microsystems for a very efficient service!

I feel your excitement. Mine is due for delivery today, also from SRS. Praying for some decent weather in Glasgow.

I'm sure it will be worth the wait. I got a Sigma 10-20mm just before Xmas and it was excellent to use on the landscapes on holiday.

Due to work I still haven't had chance to try it yet.
Can't wait for the weekend.

Should I expect a similar level of quality from the Sigma at 20mm as the Pentax 18-55mm at 20mm.
What differences might I expect to find?
If any one has made any comparisons can you let me know as I tried a few shots in the house with flash and I am not overwhelmed to be honest.
Does anyone know of any quality control issues with the Sigma 10-20

I doubt I'd be overwhelmed by any ultra-wide using with flash around the house - be it a £300 Sigma or a £3000 Leica...

Why don't you wait until you can try the lens properly before you get too worried.

I've seen some stories about de-centred Sigma 10-20's but it seems to be reasonably rare (given Sigma must be selling a lot of these lenses). There are quite a few owners on here (including me) and I think most (perhaps all) have been happy with theirs.

I have both lenses and don't find the 10-20 overwhelmingly better than the 18-55 at 20mm.

However, the fact that it goes down to 10mm (and with minimal distortion) and produces generally good results delights me. Some of favourite photos were taken with this lens - and I could not have afforded anything else that would do the same or better when it comes to the wide end.

The Sigma's resolution at 20mm is similar to the Pentax's at 18mm according to Photozone. See:

Not a great pic I know but one to check the focus, of which I am not sure. Is this acceptable for Sigma 10-20mm

Hi MX - looking at the exif - 1/500, f4, 200 at 10mm - and at the pic and realising that I'm new at this too - I'd say the lens was good. I read about some left and right edge soft focus issues but from what I can see yours looks a bit soft but OK.
Get out of the woods and try taking some snaps in good light of some buildings near you and post them up to let us see.

This lens is the most expensive I've bought but money well spent - it's my most used.

Many thanks for the reply, I purposely shot it at f4 because it is a bit extreme. Another at f8 is better I feel, but you have comforted me. Today was the first day since I got the thing that I have been able to use outside and it was near home before I went to work. Yes, the local buildings will get some attention soon. Have you seen tomorrows forecast ?
Maybe next week then!

Parts of the pcture look sharp to me - particularly the second front tree from the left (with the whitish bark), towards the top.

The lens could be faulty for all I know, but I suspect the focusing and aperture and post-processing could have been better to make a sharper picture altogether.

I've posted a few of my pictures with this lens at 10mm at www.pentaxuser.co.uk/forum/viewtopic.php?p=49386#49386

Still not sure of the sharpness of the lens, but I haven't been out much.
Please comment on the quality of the lens in this pic, taken at 10mm f8

Was this tripod mounted? I see you have a 1/15 shutter speed. To slow to get decent images without a tripod - If you want to judge the sharpness.....

No tripod, but shake reduction on, which should be good enough for 10mm @ 1/15
