Pros: Sharpest lens of canon and very usabel with 1.4 and 2.0 converter on every canon camera.

Cons: Sometimes weight.

Opinion: My best lens and most time on my 7d mark ii, the best of this lens is that you cane use it with de 1.4 and still is very sharp. With 2.0 in good licht and not to much distance also good usebel, i use then most of the time F7.1 ore more. In the netherlands i use it the most time for birds and than is 300 mm to short. Very usebel for dogs, very sharp at 2.8 and nice bokeh and nice far from the dog so he won't notice you so you cane make nice pictures.

Pros: General quality, detail also at TA, natural colors... everything, come on.

Cons: Perhaps, several years after the purchase, the weight: it is true, however, that a lot of time has passed.

Opinion: Purchased on occasion but practically new with top case in 1999, initially used in analog with EOS 1VHS gave pappina to the 300 f.2,8 Nikon contemporary, had and exchanged with this (for my use; Fanboys no comment ). Amazing detail at f.2.8 and improvable up to f.8-11, also used duplicated at 2x lost very little. Reflexes contained all in all but to be used with the hood, uncomfortable but effective. Excellent performance also in digital and the shots with the very old 6D testify to this ... Sold in 2011, at 60% of the price paid, and regret for quality and satisfaction obtained. Rating: 10 and 1/2.

Pros: Sharpness, color rendering, bokeh

Cons: Weight, noisy and poorly performing stabilizer

Opinion: I have owned this fantastic lens for some time now and I am very happy with the purchase. It manages to give very sharp images even when multiplied with the 1.4x III (I have not had the opportunity to multiply it with 2x III for the moment), but what I think is its strong point is the color rendering, the nuances and the blurred. Perfect for sports and nature photography (of course it is short for birdlife, but for mammals and maybe in Safari it becomes really perfect) It has its years, and consequently it also has its limits: that is a very noisy and poorly performing stabilizer compared to today's standards, and an important weight. Its 2.5 kg are not few if you plan to use it freehand also considering the fact that it must be combined with an important camera body and then you have to start thinking about carrying at least one monopod. The AF in my opinion is still very valid even if I must admit that with the multiplier sometimes I have to "help" it with the manual bezel, but this is perhaps a limit of my camera body (5DsR) In conclusion I think that nowadays this remains a very valid lens considering the quality / price ratio, (on the used market it is also found at 1400/1500 EUR) and I do not think you can find another lens capable of giving similar images in this band.

Pros: Sharpness, construction, fast AF, usable in freehand

Cons: If I propose I have to find it, ff without multiplier could be short, but it always depends on what you want to photograph.

Opinion: Exceptional optics, bought for use in the release period of the Series II. Exceptional sharpness already at f2.8 but from the best of f4 af 10, I use it with extended canon extended 1,4II and I have to say that it behaves very well, although at f4 "it loses a bit of sharpness" ( But it's really good, but it's almost entirely f5,6.rnil bokeh is fantastic, contrasts with perfection with its sharp clarity, its use for naturalistic photography, tend to employ it between f5,6 and f8 allowing light but it is It's a real pity because it's fiddling between f2.8 and f4, ideal if you want to make close-ups of animals or if you're trying to get rid of the exaggerated background. This optic has always been presented as one of the best ever made by canon, and after Having tried the series II I can say it's really cool !!!! Obviously the new one is better in many respects, but if you do not use it for professional reasons, you do not even notice the difference.

Pros: Sharpness, blur, lower price between the big lens, well used freehand

Cons: Usually short (without tc) for wildlife photography.

Opinion: Considered the best super telephoto Canon as sharpness, until the advent of the next generation. I do not know whether it is the best but certainly not the fame is not misused. We can talk about problems flare (hood generous) or vignetting. The blur is pleasant and exceeded (probably) only by the 400 f2.8 due to the greater focus. But it is also a versatile lens: 1.4x tc with becomes a 420f4 and the 2x tc becomes a 600 f5.6 If the 1.4x tc you will not notice significant differences will nell'autofocus it in image quality with the 2x tc however the difference note: can also be used at full aperture even though I generally prefer close to f8, and the autofocus is affected by a lot of the doubler 2x (experience 40d and 7d). Usually I prefer to limit then the 1.4x tc, but if the situation requires it, I am not ashamed to use it 2x tc, nor to use the tc 1.4x combined with the 2x tc (but I recommend not to photograph the heron that see it every day ...). In only one case (young eagle in a shed while waiting) I used two tc 2x combinatthe assembly, and if the result is certainly a miracle is still in worthily Printable 20x30. Objectively speaking, the 300 is short for wildlife photography (500 f4 usually better), especially in Italy. But its versatility makes it still more than adequate, and if you can shorten the distance, it becomes super. I have no experience on sports photography that guess work very well. The new super telephoto out of which the first examples while writing promises to improve some aspects of this model image quality even higher is better autofocus speed with the new multipliers. The quality of the already consider surprising therefore is a welcome improvement but not strictly necessary, while the speed of autofocus (if the premises are observed) would increase the versatility and usability even with tc.
