Canon EF 100mm f/2.8 USM Lens

Pros: Minimum distance (310mm), fast optics, great sharpness, good for portrait and Macro
Cons: No environmental seals, no IS, relatively long

Optical quality has become more and more of an issue as digital sensors are more dense with any new release and already surpassing standard film grain. Hence the sharpness (a.k.a. contrast) of a lens is more important than ever. Prime lenses are at an ...

Pros: Clear, great price, great contrast, well made, did I say clear?
Cons: Um. Uh. No.

I am a somewhat versed, but definitely not professional, hobbyist photographer. As such it is my lot in life to improve my equipment--my lenses, my camera, my flash, etc. This is a never-ending job. One that exists for all photographers with SLR ...

Pros: Sharp sharp sharp; manual adjustment for autofocus; great contrast, color.
Cons: Have to back up a long way for portraits and regular shots.

You've heard "sharpness" tossed around, and you may think you know what that means. But unless you've been shooting with L-series lenses, you'll see so much more detail than before, you'll have a whole new appreciation for a "sharp" picture.Ever ...

Pros: Sharp, well-built, sharp, quick AF.... and did I mention SHARP?
Cons: No lens hood included. That's it!

Well, after lots of umming and aahing around (or as my wife called it 'faffing around'!) I could not put off the decision any longer. I have always loved macro but have felt my limits were being exposed by using just extension tubes or close up filters. ...

Pros: Incredible image quality. Well built piece of glass
Cons: Why didnt I buy one sooner?

There is a short list of lenses that every amateur photographer should have in their bag-- basically, a long zoom and a short zoom. When I recently purchased my Canon EF 70-200mm f/4L, I had satisfied my desire for a high quality long zoom, and I ...

Pros: Excellent image quality…speedy focusing!
Cons: A bit more expensive but no truly negative considerations, yet.

It was Thursday that I bought a Sigma 105mm macro-focusing lens. Friday, the auto-focusing mechanism failed and I upgraded (paid a bunch more money) to Canon's 100mm, f:2.8, macro lens. I immediately headed out of the camera store with my second new ...

Pros: Solid, quiet, sharp, versatile, fast, dependable.
Cons: None to speak of.

Photography - buy a camera and start shooting, right? Not if you are serious about it! I have owned cameras since I was in grammar school and the passage of time has taken me from a Kodak to a digital SLR. I have a family to consider so adding to my ...

Pros: small compact 1 to 1 macro lens
Cons: have to be really close to get good macro due to small focal length

This is one sharp tight little macro lens. This lens brings small tiny things up to life size 1 to 1 ratio.
its small compactness is nice to cary around with you in the field.

Several things I would recommend you get if you buy this lens...

Pros: IMAGE QUALITY, SHARPNESS, COLOR RENDITION, VERY SHORT DOF. GREAT FEEL ON DIGITAL REBEL. VERY SHARP!!!!
Cons: HOOD NOT INCLUDED, FOCUS RING MAY BE A LITTLE LOOSE, MINOR GRIPES, CONSIDERING IMAGE QUALITY.

I PURCHASED THIS LENS TO SHOOT FLOWERS IN MY MOTHER'S YARD,
AFTER READING SOME PRETTY HEFTY REVIEWS. THE REVIEWS WERE WELL DESERVED. THIS LENS IN JUST A VERY SHORT TIME AND A FEW
HUNDRED SHOTS HAS BECOME MY FAVORITE. SHARPNESS, COLOR AND BOUQUET ARE EXCELLENT. THIS IS MY FIRST TRUE MACRO & IT TAKES A LITTLE TIME GETTING USED TO THE VERY SHORT DOF. IT HAS FORCED ME BACK INTO SHOOTING WITH A TRIPOD A LOT MORE, BUT WITH EXCELLENT RESULTS. I HAVE TWO 'L' SERIES LENSES THAT HAVE BETTER BUILD QUALITY, BUT I FEEL THAT THE BUILD QUALITY OF THIS LENS IS REASONABLY SOUND. THE IMAGE QUALITY IS ON PAR WITH WHAT I GET WITH THE L LENS. VERY SHARP LENS..
OH YEAH, I REALLY LIKE THIS LENS.

Pros: It is light, works as expected, and is worth the money.
Cons: None.

I use a Canon 10D and wanted to get a solid performing macro lens. The Canon EF100mm Macro lens is fantastic! Pictures are crisp with true color rendition, and AF works superbly. The 1:1 image ratio makes this a very practical macro lens for any use. I shoot in RAW format, so I can manipulate images in post production. This lens makes it very easy to be creative.

Pros: Amazingly crisp, sharp, great price/performance, f/2.8!, beautiful bokeh, fast focus, USM
Cons: heavy (a lot of glass!), cost (its worth it!), no lens hood!

This is truly a great lens. Up until this point, all of my lenses were zoom lenses and I was worried that I may be at a disadvantage shooting with a prime. I was wrong. This lens, forced me to rethink some of my shots, and it forced me to move instead of moving the camera.

The lens also is a great macro lens. Pictures are always sharp and very crisp. Out of my 4 lenses (70-300, 28-90, 18-55, 100) this is my favorite and my most regularly used lens.

The lens is a little heavy, but the big aperture and quality of images makes up for it. The price is high, but for what you get, its a great deal. With certain digital cameras, there is a focal length multiplier, and so this lens becomes a 160mm macro.

The lens is very fast to focus in medium to bright light, and in low light, its a little slower. USM means its virtually silent.

My one gripe is that it doesn't include the lens hood... come on Canon, I'm paying nearly $500 for a lens and you still want to charge me $60 for a lens hood?!?
