Quirky, but worth it

7. November 2005

When I first started looking for a mid-level macro lens, a few weeks ago, I was naturally drawn first to the Canon 60mm, as I have already have 2 Canon bodies.

But then I started looking around, reading reviews (mostly on Fred Miranda's site), and comparing prices. The more research I did, the more appealing this lens became. And finally, I decided to go with it.

Here's why:
- The price is similar to the Canon 60mm.
- I already own a Sigma EX-series lens (17-35mm), and really like it. I like the matte finish, and the glass is excellent.
- For some reason I cannot fathom, Canon doesn't include lens hoods with any of the mid-range lenses I looked at. Sigma does.
- The greater focal length means I can stay farther from the subject - minimum focus distance is about 30cm (12in). This is almost always a benefit.

This lens isn't perfect, however, and here's a few caveats you may want to consider before making a purchase:
- In low light (ie, most macro photography), this lens likes to hunt. Which can be a slow process considering its length when fully extended. Personally, I don't mind manual focus all that much, so this doesn't bother me.
- This is a not an HSM (Sigma's version of USM) lens. It is motor-driven. This might bother you, but I barely even notice it.
- Switching to/from manual/autofocus mode is a 2 step process. Beside the switch on the side of the barrel, the focus ring requires a push-pull motion which is sometimes a bit tricky. With a little practice, this becomes less and less of an issue - and if you leave it on manual most of the time (as I do), you seldom have to worry about it.
- The lens hood is a screw-in, not a twist- or clip-on model. This is, however, offset by the rather deep recession of the glass in the lens tube. (If you want to use the lens hood and leave it on, a 77mm lens cap will fit it.)

Despite these (in my opinion, very minor) problems, I'm very happy with this lens, and would definitely recommend to anyone looking for a mid-level macro lens

Worth every penny

15. May 2006

I've been using this lens for about 3 months now on a Canon EOS-350D and the Canon 5D. It has supurb optics. At f2.8, it is sharp. From f3.0 it takes off and stays sharp up to about f14. The focus mechanism is a little different from most other lenses, but actually I've grown to like it. With a push-pull lock at the end of the lens for manual-auto focus, you can put this thing in manual mode two different ways. If you're focusing in, pull the mechanism and you don't have to worry about the camera trying to change focus and you don't have to take your hand off the lens to find the manual button. Really cool actually, just a little different at first. It is light enough that weight has never been an issue, though it does extend out pretty far when focusing. Focus speed is not as fast and there is a little more motor noise, but this too is never an issue as all my close work is manual focus. As a telephoto, it works very well, but the autofocus speed comes into play here. It will hunt in some conditions as a telephoto, but it is pretty accurate.

Save some money and take great SHARP shots with this lens. Highly recommended!

Wonderful addition to SLR photography!

3. January 2007

The sigma 105 macro lens is a great way to explore new worlds with macro photography. I am using this lens with my 300D Digital Rebel and the results are fantastic. Now, small areas in my backyard and local parks offer unlimited photo opportunities. I would, however, offer several tips for beginners with macro photography. First, and foremost buy and use a tripod. With many subjects, depth of field is critical and any movement whatsoever will be evident in your images. Second, if your camera can allow it, use mirror lock-up and a remote release to prevent movement. Third, have plenty of patience! Expect to take a lot of images to come up with keepers. No big deal for digital cameras, and don't be afraid to experiment.

Here is a fun project that I have been using with this lens courtesy of my high school photography teacher:
Take a nail and tie a 10 ft. piece of string to it. Then, as you are walking along a trail or path, randomly stick the nail in the ground. You now have a circle with a 10 ft. radius. Challenge yourself to shoot 10, 20, 50 or even 100 images within that radius. It will certainly cause you to look, and more importantly see differently.

This purchase is perhaps the best piece of equipment that has helped my photography.

Excellent macro lens for dentistry

25. November 2007

I have employed my Rebel XT digital SLR into my dental office. I upgraded to the Rebel XTi (10 mpixels) for home. I purchased the Sigma ring flash with a Sigma macro lens for the Canon SLR family. If you look at the Lester Dine website this is basically what they sell for a few hundreds dollars more.

I compared the ring flash and lens with the ones offered by Canon and felt that it was worth saving $300 by purchasing the Sigma combo.

The macro lens/ring flash work well for dental purposes. After a little experimentation I discovered that I get the best images by using the aperature priority setting. All settings are used with ISO 400 speed. I set the aperature at 14-16 for intraoral shots. This gives the best depth of field. I also use the operatory light for intraoral shots. I set the aperature to 6 for full face shots.

I use autofocus but set the ratio to 1:2 to 1:3 for intraoral shots. This keeps the autofocus from "hunting". I frame the shot by moving towards the subject. Once I get close to the image that I like I use the autofocus to get the final focus for the picture.

Great lens

12. May 2007

I was looking for a macro lens to shoot detail shots of my knitting for my blog and a friend recommended this lens to me. I'm not a great photographer, but I've been able to get some really spectacular shots with this lens on my Canon Rebel.

super sharp, a great value compared to other brands

16. December 2006

I previously owned the sigma 150 macro. It was super sharp and awesome in any way, just kind of big and heavy. So I decided to get the 105mm because it's cheaper and lighter, more likely to stay in my bag. The 105 lacks HSM but that's not really a problem for macro where you use manual focus, or for portraits where you don't need fast focusing. The min focus distance is about the same.

I didn't get the 60-70mm macros because I also want to use the lens for portraits and 105 is better.

I researched the tokina & tamron equivalents but I choose sigma cause it was cheaper. The reviews say they're all about the same. I agree the Tamron 90 macro is better but it's a lot more expensive. Plus I think 105 is better for portraits.

Overall I highly recommend this lens for nikons. For canon bodies, the sigmas typically front focus and I would only buy canon lenses (canon has a good 100mm macro).

I am absolutely loving this lens!

27. April 2008

Originally I didn't want to stray from Nikon products, but Sigma definitely has my attention. This is an excellent lens in both build quality and function. It works flawlessly on my Nikon D40, metering perfectly and in addition, even though it's manual focus on my camera, it is spot on with the auto-focus indicator light (lower left corner of view finder). I highly recommend this lens to anyone who is looking to get into macro! Don't be scared if you're a Nikon D40 user, I was at first, and now I'm hooked on this lens! Do yourself a favor and buy one!

Sharp and well-built

14. January 2008

I debated between this and the 105 Nikkor but at $ 350 versus $750, I decided to try the Sigma and return it if it was not satisfactory. The build seems good with a very solid feel and, while the autofucus is a bit slower than the AF-s Nikkors, it is fine for all but the macro shots which need manual focus anyway. Comparing sharpness at f8, it is about as sharp as my 18-135 at the center and much, much sharper as you move from the center. Overall, I'm very happy I saved the $450.

Be aware... I wasn't...

14. February 2008

I am sure this is an excellent lense - jus be aware that if you use it in AP mode on your nice new D300 etc you will need to set the aperture manually on the lens... It is not full auto like a Nikon AF lens...

I was disapointed when I learnt this...

Oh well...

Great Macro Lens

3. July 2007

This lens was exactly what I was looking for. It is fast and sharp.

Sometimes, however, it has troubles finding the object during focus and travels the full length. I just switch to manual focus to get around that issue.

Highly recommended!

sigma macro lens

25. October 2007

excellent product with excellent service from the supplier. My son loves his new lens. Far exceeds expectation.

Great image quality and solidly built

21. August 2008

If you wanted to try out some true macro photography this is good lens to start with. It provides a decent working distance to the subjects and also doubles as a very nice portrait lens. It's quite sharp even wide open and it renders colors and blur very well.

Works fine

26. November 2008

I use this lens daily in my dental office with a ring flash. It is big and heavy but takes great pictures. It is not a versatile photo item and has specific uses. I would not take it on vacation but it is excellent for telephoto, portrait or close-up, macro photos. It works well with the auto focus system on my Pentax 200D. Because of it's size, I suspect it will use up battery power very quickly if you use it with auto focus and it is forced to move alot. I use it in manual focus and just move forward or backward to get a sharp image.

One of my favorite lenses...

28. August 2006

There are several macro lenses in the 100mm focal length variety for the Minolta/KM/Sony line. They are all good lenses and offer pretty much the same problems as well. I am particularly fond of the Sigma offering. The build quality is fabulous, this is a very very solid lens. The photos are tack sharp and colors are well-saturated and lovely. In the US, the Sigma EX line offers a four year warranty and it is the least costly of the high quality 100mm trio of lenses. Highly reccomended. Here is a link to one of my favorite flower shots form this summer (2006).

Fantastic lens

19. July 2008

This lens is just awesome. I use it all the time and the results are outstanding!

Sigma Macro Lens...great buy!!

18. September 2008

This lens is worth the money. I found that it is a bit slow to focus in AF mode, so I use MF mode instead. It produces lovely, sharp photos in 1:1 macro, portraits, and in hyperfocus depth of field landscapes. Once the lens has focused it becomes very quick thanks to it's F/2.8. It also has a good quality feel to it, much better than the kit lenses that come with the Sony SLRs. It feels sturdy in hand with a good weight: not too heavy, but not too light.

Good but not excellent...

22. December 2008

The lens is good, however the zoom can't move (it's fixed) so the zoom are your (my)legs... You have to get a distance of your object to take the shot, cause you can't manage the zoom. The image is good, but in indoor sports with my Sony A200 i just can shot in S Mode, 1/250 (no flash)to get good photos.

Sharp and clear

8. February 2007

Of all my Four-Thirds compatible lenses this has become a favorite. The Sigma is sharp, reasonably compact and features an actual manual focus mode. Yes, the 50-200mm Zuiko covers this range and is just as sharp, but this lens is much smaller and lighter than the Olympus lens and is, of course, a macro lens that focuses much closer than the Zuiko 50-200mm.

Despite being optimized for macro photography, this lens works quite well for general photography and has a bokeh that is a bit more pleasing than many of the admirably sharp Zuiko lenses. In macro operation the lens often gives a greater distance from the subject than the Zuiko 50mm macro lens does, but this lens is not (as far as I can tell) able to mount the Olympus ring flash for macro work so I use it strictly for outdoors and ambient light macro work (Edit: I have since purchased the Olympus twin flash and it works very well with this lens via an easily obtained step ring adapter.)

The build quality of the lens is not up to the level of the better Zuiko lenses and it is not a weather sealed lens but it is certainly of a higher quality than the Olympus kit lenses that normally ship with cameras like the E-410/510. It's also a higher quality lens than the inexpensive Sigma zoom lenses that have been available for Olympus and other Four-Thirds applications for some time now. I would say that it has a nice feel to it both in heft and in operation.

Due to optical designs that I do not pretend to understand the front element of this lens is remarkably deeply recessed into the lens housing. In fact, it's so deeply recessed that I don't feel the need to use the supplied screw on sun shade (which is a poor design in my opinion) nor do I feel the need to use a clear filter in order to protect the front element (it would be difficult to bang it on anything given how far from the front of the lens it is). One might view this as a money saver as well as a convenience but that's a very subjective opinion I do admit.

Finally, the lens features a fully manual focus mode that works very well but unlike the 'fly by wire' Olympus lenses that many are familiar with this lens requires that you throw a switch on the side of the lens housing in order to disengage the auto-focus motors. This is not terribly convenient, however with practice one certainly can train themselves to operate the switch without taking one's eye from the viewfinder.

To sum it up, I did not expect great things from this lens given that some of the Sigma lenses in the Four-Thirds mount have been a disappointment but I was pleasantly surprised by this lens. It is sharp at maximum aperture, it is moderately priced, it is an excellent macro lens, and it is a fine medium telephoto lens on top of it all. I can highly recommend this lens as a handy addition to any Four-Thirds DSLR camera kit provided weather & dust sealing is not required.

duct tape to attach ring flash

5. January 2008

I attach the olympus ring flash using the sigma hood (which comes with the camera) and a little duct tape. it works great.

What a great little lens!

18. June 2008

I've owned this for over a month and have shot close to a thousand pics with it. It is fast - f2.8 - accurate and produces closeup shots with great detail.

It's also a great ''walk-about'' lens since it focuses from 12 inches to infinity. And the 105mm length (200 mm equivalent on a 35mm slr) is a great medium-telephoto length.

The unit is well built, solid and light enough to handhold. I own it in a 4/3 configuration (Olympus E-500 camera) and love the ability to switch from auto to manual in about 2 seconds, and to limit the auto focus to a limited range at the touch of a switch. I found that I can switch from auto to manual without looking, and love the large focus ring.

I use this coupled with the Olympus 25mm macro extension ring, and it produces amazing close shots. The lens itself is 1:1 and the extender boosts that considerably while retaining all my auto lens settings and capability.

I don't mind the matte finish, and love the fact that it doesn't generally need a lens shade because the front element is recessed quite a ways into the front of the housing.

I've been using some old Nikor and Sigma manual lenses from the 1970s, 80s and 90s, but they can be frustrating to open the aperture and focus and then stop down to shoot - especially with insects. By the time I open the aperture, focus and stop down they have often moved. And when a manual lens is stopped down to f/8 or f/11 it's too dark to see what's going on. The Sigma being coupled with my camera's electronics solves the dilemma and delivers bright views to the viewfinder.

You cannot preview the DOF, but a quick shot and chipmunking the viewfinder will show you what's going on.

I'd recommend this lens to anyone who is serious about macro work, and doesn't want to pack a ton-o-gear around with them. Being able to carry just the body, lens, and extender plus a tripod is enough gear to do some serious shooting.

Super-sharp optics for DSLR

21. October 2008

I purchased the 105mm F2.8 EX DG Macro to compliment my "standard" 18-50mm F2.8 zoom for my Sigma SD14. The lens is tack-sharp from f5.6-7.1 up to f11 plus... Produces bright, clean images and the large aperture gives superbright finder views (great for my elder eyes). Compact size, love the focus limit feature; like all EX Sigmas, the lens is well constructed and beautifully finished. Focuses quickly, even on the marginally slow SD14 body. Super deal here on Amazon. With crop factor, focal length == 179mm on SD14. Would recommend to all, regardless of camera body decision. 5 stars!
