Fantastic lens

[...] Ill just get to the point. This is a very unique lens. The highlight of this glass is the fast aperture of f1.4. But this is no ordinary f1.4, it gives a wicked look to photos. The bokeh and color is like no other even when closed down a bit, its very difficult to describe but there are many sigma 30mm f1.4 lens enthusiasts on flicker. It is very difficult to manually focus wide open but thats to be expected with any lens with features like this. One thing to note is that this lens has ...

[...] Ill just get to the point. This is a very unique lens. The highlight of this glass is the fast aperture of f1.4. But this is no ordinary f1.4, it gives a wicked look to photos. The bokeh and color is like no other even when closed down a bit, its very difficult to describe but there are many sigma 30mm f1.4 lens enthusiasts on flicker. It is very difficult to manually focus wide open but thats to be expected with any lens with features like this. One thing to note is that this lens has extremely low edge resolution but makes up for it in very very sharp center resolution. Even when stopped down a bit it is still noticeable that the edges arnt that sharp but once stopped down to maybe f4 and up, it gets far less noticeable. Many people the soft edges a downfall however many people like me find it wonderful. Infact that’s the reason I bought this lens, for its soft edges and extreme sharp center. Its so much more fun and feels more real when you have a lens that optically creates theses effects rather than the computer, I believe this will help spark creativity. The sigma 30mm is very rugged and looks nice when paired up with the a700 but I am sure it will look just as nice with any other camera you attach it with. It makes for a very compact setup however thats if you use it with "out" the lens hood. That lens hood is almost the length of the entire lens itself, and its a absolute must if you plan on shooting where the lighting will almost guarantee glare. Very tough construction. The focusing ring is very smooth but I wished it had alittle more resistance feel to it. Hmmm what else, o yes, the when you focus, there is no increase in the outer dimensions and there is no rotating of the threads, so filters are easily attached.All in all, a wonderful lens, I have heard that Sigma is rather a company that has problems with quality control and I believe it. I find many people complaining about how there lens won’t work right and have to return it to get one that actually works like it should. In this case I got it working right from the box. But don’t let peoples complaint stop you, I was well aware of them when I purchased it, in my mind I said "if it comes to my house and it is defective I will just keep returning it until I get a good one". I know it sound silly but I fell in love with the image quality and how amazing this lens is. I almost forgot to mention, when you photograph a person close up wide open, it has this wicked effect of making that person look like a doll, no quite literally look like a plastic doll, amazing! But if you don’t want to do that you could just stop down to like, o I don’t know f2.8 and up and it will look quite normal.

Killer lens!


from Hendersonville  -  Photo Enthusiast

You need to have this in your bag! I bought this lens for a few main reasons. I wanted a really fast aperture for low-light conditions and a prime lens. The Sigma for me has it all. Its sharp, crisp and extremely quiet. Auto focus at f1.4 for me was a challenge at first. the more you use it the easier it becomes.

So far so good


from Iowa City  -  Photo Enthusiast

I've had this lens for about two weeks. Not a lot of time to develope an opinion but just some initial observations. It's going to be best as a portrait lens, the focus is sharp and accurate when the subject is close (say 2-12 feet). I think the focus speed is good, but not as good as say my Nikon 17-55 or some other Nikon AF-S lenses. The biggest drawback or deficiency seems to be focusing on subjects that are 15-35 feet away. Maybe since the angle is wide, faces are small at that distance but for whatever reason it is consistently out of focus at those distances. AF tracking is not super fast and responsive as say a Nikkor AF-S lens. On the plus side a close subject is always tack sharp, the contrast is high and the colors are vibrant and crisp. I don't know if it will be a good landscape lens given that it does not seem to focus well at distant subjects. OTOH, it is sharp (when its in focus) and it renders colors and contrasts well. So if you're shooting on a tripod and have time to manual focus, maybe it will be a good landscape lens. The construction seems rugged and tough. Overall I think the lens is a good bargain.

Out-of-this-World Performance


from Newtown, PA  -  Pro Photographer

I paired this lens with my D7100, and when I look at the results, I think I'm shooting with a medium-format digital. I couldn't ask for better color, sharpness, autofocus, build quality - you name it. In the week I've owned, it, I've used it for nature, landscape and city walkabouts both day and night. It has the perfect focal length for all kinds of general photography in the DX format. And the 1.4 speed opens up great possibilities for low-light and subject isolation.


Great lens


from Amsterdam, the Netherlands  -  Semi-pro Photographer

Real good lens for just about everything. Amazingly build, real solid. Beautiful bokeh with 9 blades


Great prime for Canon APS-C


from Madison,WI  -  Photo Enthusiast

Solid Image quality, and a much needed focal length for APS-C sensors. Focuses pretty quick, but not as quick as canon's USM. Great build quality. Highly recommended as a first prime to go with a standard Zoom. I use this alongside my Canon 15-85USM for low light situations, artsy bokeh up close, or when I want to carry around something a little lighter. Highly recommended.




from Houston, TX  -  Photo Enthusiast

Great for indoor portraits and landscapes as well. Great bokeh. Some problems with consistency in autofocus, but a solid B+ in my book (I've owned/rented quite a few prime lenses and this is based on a price/performance "ratio").


I really like my new 30mm f/1.4


from Pierre Part, LA  -  Photo Enthusiast

I use my new lens for low light applications, I also got is at a great price on sale.


Superb Quality


from Las Vegas  -  Photo Enthusiast

I have a Sony Alpha 700 that I bought with a Tamron 18-250mm F3.5 lens, and I wanted a fast lens that could double for portraits as well as scenery. The Sigma 30mm F1.4 lens fits that purpose very well. It produces very sharp images in limited light situations. While the Tamron images at 30mm are fine at F4.0, they are not quite as sharp as the Sigma at that same setting. Conversely, and surprisingly, the Tamron lens appears to have a bit of an edge when both are stopped down to F16. I can only guess that my automatic spot focus setting may not have been exactly on each time. I blew up the pictures and attached them so you can judge for yourself. For wide angle photography, I am very happy to use the Sigma lens in a stitched panorama mode, so even its lack of wide angle is acceptable to me. I suspect I'll use the Sigma as my primary lens and only switch to the Tamron (zoom) lens when I can't get close to my subject.


Fast and normal


from So Cal  -  Photo Enthusiast

Although this is no tiny Pentax Limited pancake, it is not unwieldy. On the APS-C "cropped" format, 30mm is about a "normal" angle of view. For me, it is better than the 50/1.4 I had before. And, the focal length fits between the 21 and 40 I already have. Wide open is a bit soft as you would expect, and the thin DOF makes critical focusing a bit problematic. Still, I'm happy to have it though at the regular price I would be hesitant to get it unless I had a real need for it, which I don't.


No HSM for Pentax


from Long Beach  -  Photo Enthusiast

The Pentax version has no HSM. Still, it focuses pretty fast, and the noise is no worse than other lenses.
