No lens will make you a pro photographer by itself, as with any tool, you must learn how to use it and how to properly do the job you are attempting to do-- with that being said, this lens has gone a long way in improving the quality of my images, I love it's ability to produce a great bokeh and focus on the subject with great results

I also use it regularly for sport photography with excellent results.

The 24-105 has also given me great results and has a terrific zoom range on a full frame camera

If you want to use this on a Sony, you will get better results with the Sigma MC-11 and possibly better still with the metabones

I used it on my Sony with a fotodiox adapter and had good results

I hand held 200mm at 1/6th shutter with a sharp, usable result

Beyond the fact that it does give good results how can these result be described

I can get tack sharp results shooting at 1/30 sec zoomed at 200mm

I got great, sharp results at ISO 100 as long as I shot with fast shutter speeds (at least 1/125 or 1/160 at 70mm and at least 1/300 or faster at 200mm)

I thought long and hard before spending this much on a piece of camera gear, but after seeing the results have no regrets.

the 100mm f2.8 L macro and the IS on the 70-200 is better or at least is able to give better results

but if you are willing to pack the extra weight this gives essentially equal (maybe ever so slightly better) results at equal apertures and offers one extra stop

Simply beautiful results from this lens.

GREAT quality in the product and the results!

At 2 grand it seems like a reasonable investment considering the fantastic results you get.

I started shooting night football; the results were disappointing with the 28-135 f/3.5 to f/5.6 zoom lens that accompanied the camera

and I was used to having 24mm on the near side, but the results are so worth it that I don't mind walking away to get the right shots

While it has spent most of its time hand-held yielding great results, my photos of it attached to a tripod with mirror lock-up have been out of control, scary good.

I really like the flexibility of this zoom, with it's ultra sharp results and excellent color.

I am not too happy with the 24-70 L it lacks sharpness and color if I am any

L look somewhat soft, even after being micro-adjusted.

Solid build and a great "L" lens

Durable L quality

I have used and owned numerous Canon lenses, and this is the best L lens, and arguably the finest

I am a hobbyist photographer, and I wanted to see what the "L-Lens" hype was all about

well maybe a nice L 50mm)
