SIGMA 10-20mm CLUB

Not the most interesting landscape, but I like it for the sense of distance created by the objects of varying closeness.

Another 2 pics shot during the boat cruise at Tianjin.

Thanks very much Tamia.

Took a hike through the above mentioned park on a beautiful Spring day on Saturday. Perfect day for hiking, and the Sigma 10-20 was "big" enough to cover the whole falls while standing in the middle of the creek about 25 feet back. Perfect lens for this application.....

Mike, I like that landscape very much. It's sharp all the way through, and the mountain range looks familiar.

Ken, lovely watery cityscapes as usual.

Tim, Very appealing waterfall and an excellent capture. The colors in the water are very nice.

Nothing very special about the following shots, but I thought folks might like to see what the transition between late winter and early spring is like in the northern Adirondacks of NY. These are of Chazy Lake, and the bulky mountain in the background is Lyon Mountain. It was a cool day and heat shimmer distorted the last shot, which I hope you all will forgive, as it's a telephoto (Pentax 55-300mm) of the emerged catkins on the aspen trees. In some of the shots you can see rotting ice on the lake in the distance.

Thanks Tamia for the nice comments.
Also thanks for sharing pics of season transition which I would not have chance to experience in Singapore.

I was just lucky to have taken a few shots 2 wks ago at 3 deg Celsius in China. Still managed to see a thin layer of ice on the lake.
I would be even happier if the tour guide allows more time for photography, hence none of the shots is taken with tripod and ND filter.

Hello,

I am seriously considering buying this lens, but due to budget constraints, I can only afford the 4-5.6 version- is there any major difference between this and the 3.5 or is it mainly speed?

Thanks!

Designosophy · 04-22-2012, 01:29 PM

Kengoh, Tamia, UpNorth - some very nice photos. Kengoh, I particularly enjoy the color of the sky and the lake in those shots. And Tamia, that photo is from Satwiwa in California. I believe I'm looking NNE, and I'm not sure what those mountains are called.

Doesn't the f/3.5 version actually have HSM? I've never used the f/3.5 version, but the 4-5.6 version is wonderful, especially when stopped down.

Ahh, I was alluding to the differences between the lenses in terms of IQ. Surely HSM isn't that much of a concern since the 4-5.6 (from what I've heard) focusses quite quietly and quickly anyways?

Both models have the same number of lens elements and groups, and the same number of diaphragm blades. The 3.5 has HSM, which works very well on my copy, but the filter size is bigger (82 versus 77 mm).

Am I right in thinking that HSM is purely for silent and quicker focussing? Whilst that is nice to have, unless the focus noise is ear-splitting I think I can live without it...

I never found the noise intrusive or the focus slow. Never used it below f8.0 either. 77mm is a far cheaper option for filters than the 82mm as well.

One not really looked at before but going through the hard drive clearing space.

Not having used the 4-5.6 version, I can't compare the two, but the HSM is remarkably quiet and smooth in comparison with my non-HSM Sigma (a 105 macro) and is as quiet as the SDM and DCM drives in my other Pentax lenses.

I also have to agree with mark lj's comment about the filter size - 77mm is a lot more common than 82mm, so you're more likely to have to buy filters specifically for the 3.5, unless you don't already have some thin profile ones (to avoid the possibility of vignetting).

I would agree with you on this, as most real-life shots with the 10-20 will be at hyperfocal anyway. Anything focus-related is basically a non-issue with this lens.

Thanks Tamia. This lens sure does do a nice job with color.
