Sharpness, contrast, color. Very well built. Fast and smooth focus.

Minimum distance from the subject is still too far.

After using this lens for over a year. All I can tell is that this lens worth every penny I spent. It give me very sharp picture with very nice contrast and color. The zoom and focus ring is very smooth. Autofocus is super fast and quiet. For the price, it is one of the best value in Canon lens.

If you are looking for a lens in this focal length and don't really need f2.8, I would highly recommend it.

Haven't found any to date.

I/ve used this lens for the past six months now, predominately in aviation photography. To date I can not find one fault with this lens, Needle sharp and focusing is instantaneous. For 'L' lens quality the price was good. The type of photography I do is outdoors under ideal lighting conditions, therefor I really don't require the faster 70~200 and am still physically capable of holding it steady. It is mounted on a 20D and XTi and It has just done a great job for me, and would recommend it to anyone shooting under similar lighting conditions...

Outstanding image quality/color reproduction

About half the price of the f/2.8 version

Huge, slightly cumbersome lens hood (but it does the job)

I had to pay $114.00 extra for the tripod collar

I just bought a Rebel XT and two lenses, the 70-200 f/4L being one of them. This lens is without a doubt the best buy in a medium zoom on the planet. Mine is razor sharp even wide open and produces the most natural colors of any lens I've ever owned. It's built like a Mack truck but is relatively light and very comfortable to hand-hold. Zoom and focus rings are silky-smooth and auto focus is quick and silent. I'm sure the f/2.8 version is a fine lens, but unless you need the extra stop, I seriously doubt you'll see any better image quality than the f/4 version is capable of producing. I'm simply delighted with it. This lens coupled with the 17-40 f/4L I bought with my Rebel XT have proven to be a versatile and fun combo. Just be aware of one thing...Canon's L-series lenses will quickly spoil you. They have already spoiled me.

Fairly light and compact

Paying $100+ for the tripod mount is unreasonable and Canon resist this sort of bundled part gouging ( the same as they do with lens hoods).

Stunning lens - I wish I had bought it sooner. If you have been fooling around with non L lenses, this one will make you a believer. I have it on a Canon 350D and while I appreciate the reach at 200mm (now effectively 320mm), I find the 70mm end ( now effectively 112mm) limits its utility when walking around with this lens mounted.
Anyway, the colors, contrast and sharpeness make your pictures look so pleasing, this lens is a bargain. If you need a tele zoom, don't even think about it, buy this one.

Incredible. Small, sharp even wide open, light, smooth, fast focus, well built.....If you into travel photography this is a great lens. in at f4 and 5.6 for portraits. With the price saving over the 2.8 you could pick up a dedicated portraits lens such as the amazing 135 f2 L which gives to me a better combo than one 2.8 70-200.

I cannot fault this lens and make no mistake, it is VERY sharp and in an entirely different league to consumer 70-200s in terms of image, focus and build.

doesn't come with tripod mount, spend the extra to get it!

i really couldn't be more pleased with this lens. first L glass, and it's worth every penny. great colors, sharp as a tack. light enough to take hiking, etc. in combination with a shorter zoom lens and 100mm macro, i've got all i need for traveling.

Excellent contrast , colour and sharpness at every aperture. Comparing to consumer zooms results are fantastic.

None really.

This is a heavy, solid built lens. It is well built for outdoor use with an excellent deep hood(supplied). It is a top performer with an excellent bokeh. I find its results as good as a prime lens. Itis my first L lens and it is well worth it not overpriced compared to its siblings and others.

good walk around lens, quiet and fast focusing, good price new, sharp images, great bokeh.

No tripod collar(expenssive to buy), not ideal for indoor or low light.

Well after owning a Sigma 70-300mm APO Macro DG and getting this lens, it’s definitely a different league. I do think that the Sigma lens is a great all around consumer lens for the price, but it just wasn’t cutting it for me. I quickly learned that you have to pay the price for quality glass, and the only serious “L” series lens I contemplated on getting was the 70-200mm F.4 L and the F2.8 and the 2.8 IS version. Both F2.8 was way over my budget and though I would’ve loved this lens I found myself looking at the F4 and found a great deal for a used one. A few days later and $600CAD later I was a proud owner of the Canon 70-200mm F.4 L Image Quality: I was immediately impressed with the quality of images this lens produced. Color and contrast was richer, bokeh is very smooth and with a steady hand or mounted on a tripod this lens produces sharp images. I compared my shots with the Sigma and though the sigma got soft from 200-300mm it wasn’t that far in sharpness compared to the Canon lens. However, the bokeh is much nicer and because of this, in my opinion the canon seems sharper giving the image a 3d look. The images seem to pop out at you. If you are anything like me, I still had a hard time getting sharp images on the long range due to my own lack of ability to hold the camera still, stopping down helps combined with a higher shutter speed. This is where I wish I could afford the 2.8 IS. However with good technique images are sharp on all focal lengths. I still have much to learn in regards to technique. This lens also makes great portrait pictures, great for outdoor shots. I use this lens with my Canon Digital Rebel XT (350D) and together, it is a sweet combination. Build: The body of the lens made out of metal I believe is very sturdy and well built. At 705g it’s still light enough to use as a walk around lens. A few people have complained about the off white color but I like it, especially in the hot sun, it doesn’t attract as much sun as a black lens would, but heads will turn to see what in the world you are holding. This is the first time I’ve had a lens with USM (ultrasonic motor). Man is it ever quiet compared to the Sigma. I was so used to the noisy motor that when I first used this lens I was pleasantly surprised how quiet it was. Focusing is fast in good light but struggles a bit in shade or low light situations which are expected at f4. The inner focusing is great as well, compared to lenses like my Sigma that extends and can attract dust. Price: For a relatively new photographer like myself, this lens is a great buy even new; however it is quite pricey here in Canada starting at $800CAD before taxes. If you can find a used one in great condition for around $500U.S I would highly recommend this lens. With the results I’ve been getting from this lens, I quickly forgot the money that was spent on it and I’m very pleased with it. In the long run, it would prove to be a good investment. Conclusion: This lens will be loved by amateur or pro, it delivers sharp quality images with good technique, compact enough for a walk around zoom. Being the cheapest L zoom lens in the “L” series line up, this lens gets top marks from me. I’ll have this lens in my bag for a long time…unless I get a wealth of money somewhere one day and I can afford the f2.8 L IS, this lens is my baby! Now I have “L” Fever!!

everything

unless you have a titanium lense mount(!?), you DO need a tripod mount - don't believe the hype

Its true! - you can be concerned about the money, you can be concerned about the max aperture, but dont doubt that this is a gobsmackingly good lense, and worth every penny...

Sharp Light Great colors and contrast Inexpensive

A bit slow.

Simply the best buy in the whole Canon line of lenses. Light and handy and easy to use hand-held, yet very sharp and delivers awesome pictures.
