Desperation option.......2007-07-10

It's hard to find a good quality A/B/C switch to use with your TV - and this isn't it. It has noticeable feedthrough from the unswitched inputs, and as a result your picture quality appears degraded. As a minor irritation, the plastic housing is cheap, the buttons are numbered C-B-A rather than A-B-C, and the switch "feel" differs between the buttons - that is, when A or C is selected, its button stays pushed in; but when B is selected, all buttons are out. If you are desperate for a three-way switch - maybe OK. At least, this one is cheap. But if you can find a good quality switch, you would be happier with it. ADDITIONAL INFO: I gave up on this switch and replaced it with two Radio shack #15-1217 A/B Switches, hooked in tandem. This allows A-B-C switching without the crosstalk problems.

Great macro 1:1 lens for close up photography.......2007-11-03

If you use this lens for macro with your Canon DSLR, beware that you should not use auto-focus. I got this lens to take macro pictures of coins and small items. I found that the depth of field is so low that the coin HAS TO BE flat and the camera dead-on to the coin. Only then will you get the whole coin in focus.

The depth of field is about 0.25mm. To get to the 1:1 macro mode, you have to be pretty far from the subject, say 10 inches. With the low DOF, you definitely have to use a copy stand or tripod because the slightest movement will cause the subject to be out of focus.

As always, the quality with Sigma lenses is here. It is a solid piece of hardware that is well-put-together. Would I buy it again? Yes. In a heartbeat. Once I get the focus down, I'll be getting better images. I have not tried it on my copy stand yet, I hope it fits well.

If you are looking for a great macro lens, look no further. However, it does NOT double as a good snapshot lens as you have to be quite far from your subject in order to fit them in the frame. With the lens that came with the camera (Canon Rebel XTi) I need to be about 50 feet from my house to get it into frame. With this lens, I need to be about 70 feet from the house to get it all in frame. Just something to think about. This is not a universal lens.

Sigma makes nice lenses, what can I say? It's been reviewed In Pop Photography. I will eventually start shooting flies' eyeballs, but it's last on my priority list.

Sigma 50mm EX DG MAcro lens.......2007-04-14

This was my first non canon lens,I was wanting a macro lens that also would be a good low light lens to use in the home to take photos of my pets at play.After reading many reviews I was concerned about the Auto focus being too slow for my needs,but I just couldn't spring for a Canon 60mm Macro at this time.
My lens came today,and I have to say I am fairly pleased.It does not hunt like my 28-135mm always has,and the AF is fairly fast,even in the low light of my living room with no interior lights on and only one window curtain open during daylight.The limitor switch does speed it up noticable as well. The colors is what has impressed me so far,The browns of my chocolate lab's coat were true,and had nice highlights I had never been able to get before.The lens fgocuses very close to an object as well,and I am looking forward to comparing my macro shots to the ones I got with my 28-135 with a macro filter applied.
There have been complaints that the hood doesnt fit the lens cap,but I think a 72mm lens cap would work well on the hood itself and would solve this problem for those who keep the hood on the lens.

Great walk-around lens.......2007-03-17

I was looking for a lens that would allow me to get good "scene" shots as well as clear close-ups (closer than portrait) for my job. I'm not a professional photographer but a camera is required for information gathering. While bokeh isn't a plus for my work, this lens gives beautiful bokeh for my personal shots. It also gives me great scene width with remarkable clarity and the macro shots are crazy-clear. Since my subjects don't move, the motor noise and comparatively long focus time I read about haven't been an issue. I haven't seen any CA with this lens and the f/2.8 is fast enough that IS hasn't been an issue. I'd advise just about anyone who uses a DSLR to have one of these lenses in his/her kit.

Great macro lense from Sigma.......2007-03-16

I would definitely advice someone to purchase this lense!! It's very clear and precise. You will not be dissappointed. I promise. This lense really takes sharp macros. Don't take my word for it, try it for yourself. If you take a dare, you will be glad you did. BUY THIS LENSE!!!

Sigma Problems.......2007-05-23

I didn't get this lens from Amazon, but I buy a lot of things from them and it is probably the best forum for review writing. I purchased this lens from a local photography chain in Russia and although it is probably my fault for not checking better in the store there was a serious issue and now I must deal with Sigma's authorized repair facility to get it corrected. The problem is that when zoomed out to the 1:1 ratio and the aperture stopped down to maximum or near maximum a lot of dust and fibers are visible on the pictures I take. It appears that this is inside the lens between elements and not on the surface outside. I had to take this to the Sigma authorized repair facility and now must wait several weeks to use my brand-new lens. I also agree that with the front element moving out to focus close that this is a liability with a macro lens. The few images I did take before noticing the problem look great after cleaning up all of the dust in photoshot so I will see what it will do when I finally get it back.

Very sharp, but..........2007-05-11

this lens is incredibly sharp and good value, but a key failure is that it does not have internal focusing. This means that your painstaking set-up can be thrown off because the front element encroaches onto your subject. To me, that's no good for a macro lens.

Sigma 70mm F /2.8 EX DG Macro Lens .......2007-02-20

I have read a lot of reviews and they all give good marks for the Sigma 70mm lens. In my opinion it's a very good lens I would say it's probably a pro lens. And probably comparable to Canon's 100mm f/2.8 lens. Though some say it's a bit soft at 2.8. Need less to say while I haven't had a lot of time to use it all the pictures I have taken it came out sharp. And at the price its cheep compared to other lens. So if you're looking for an affordable macro lens takes a strong look at this one.
