Sigma 24-60

I did a search but nothing came up in this forum on this lens. I've seen the comments in the Lens Review, but I was wondering if anybody else had good/bad experience with this,

Great Lens

Hi,

I have this lens. It's great; focuses quickly (on *ist D and *ist DS), pretty sharp wide open. I pretty much keep it on my camera all the time.

Build quality is pretty good.

It does get longer when zooming in, and it's not that great for manual focusing.

Hope this info is useful.

Very sharp (way more so than the Sigma 24-70 and I think it's only slightly less sharp than a good copy of the Tamron 28-75)...only negative I've heard about is bokeh is really weird looking sometimes...

The 24-60/2.8 EX is a pretty good lens, a pretty decent and useful range (~36-90 equiv). The Tamron 28-75/2.8 is very popular but this seems to be slightly better 'single lens' zoom range because of the wider short end.

Build is quite nice, and it is substantially smaller and less expensive than the 24-70 though reputedly just as good optically. I tend to prefer my FA24-90/3.5-4.5 but the Sigma 24-60 is probably the least expensive way to a good AF pro-style f/2.8 standard zoom. One thing that bugs me a little is that the zoom and focus rings operate in the opposite direction as the bulk of my lenses, mostly Pentax. I also find the hood a little more annoying to mount than the Pentax hoods.

I have not used it extensively because I have some other alternatives but my testing so far suggests that it is a very good zoom--I don't expect it to match primes at matching lengths & apertures, but it will generally best the budget kit-lens alternatives, and (again) offers good value as it offers f/2.8 speed where other mid-range-priced zooms will probably be f/4. AF performance seems good enough so far.

A lot of people including myself picked copies up very cheaply a few months ago when Cameta/Amazon had them for just over $200 but I suspect this supply has dried up...they are possibly being discontinued?

This is now my on camera lens.
Its sharp, good colours and fast. It isn't that big and heavy as well though i have to second AndrewG's comments about the way the zoom and focus rings operate.

It helps that it isn't that expensive either.

I believe it has been discontinued as well

I have this lens along with the Tamron 28-75 and find it compares favorably. Generally, I prefer the Tamron by just a little... slightly better bokeh and rendering imo. But in some of my lens tests, I found the Sigma to be slightly sharper, particularly at 2.8 in the corners where the difference was pretty substantial.

Here's some of my initial test shots...


Camera: Pentax K10D
Exposure: 0.033 sec (1/30)
Aperture: f/2.8
Focal Length: 45 mm
ISO Speed: 100


Exposure: 0.006 sec (1/160)
Aperture: f/6.3
Focal Length: 24 mm
ISO Speed: 100


Exposure: 0.033 sec (1/30)
Aperture: f/2.8
Focal Length: 24 mm
ISO Speed: 100


Exposure: 0.008 sec (1/125)
Aperture: f/6.3
Focal Length: 24 mm
ISO Speed: 100

This is good comparison of it compared with a capable prime lens


The Sigma 24-60mm at F2.8
















At F3.5


















F50mmF1.7 even at F2










I can tell you testing lens could be very very pleasant indeed

I love the Tamron 28-75, but I'd definitely like 24mm on the wide end!

Everything I've read says that the Sigma 24-60 is a great performer, even better (and more compact) than the 24-70 they followed it up with.

I agree with pretty much everything said upstream -- it's very sharp and nicely built. Perhaps it flares a bit more than some lenses, but it's the lens that stays on my camera 90% of the time.

I also think it flares, more so than my former DA 18-55. Otherwise it's sharp from 2.8 especially in the middle of the range. Solid build.

just got mine last night, its pretty sweet so far but i havent had much time to play with it
balances pretty well on my k10. build quality is great, and its so nice having that constant 2.8. autofocus seems decent but it hunts a bit in real low light, but im so used to manual focus at this point that it doesnt bother me much
