This is a great lens. I just bought it several weeks back and the results have been great on my Canon 30D and my Canon EOS-3 35mm film body. So far I have run one roll of Provia 100 through the EOS-3 and shot over a hundred pictures with the 30D, and I am very satisfied.
I debated between this lens and the Canon 400 f/5.6 L, like many other people out there, for close to a year. I would have liked to have a 400, but I am happy to have bought this lens. ( I will just have to buy the 400 next year :-) The extra stop (f/4 as apposed to f/5.6) was a definite benefit to me as well as the Image Stabilization. If you need 400 you can pop on a 1.4x tele-converter and get out to 420 at f/5.6 and still have IS. The results with this lens and the Tamron 1.4x PRO Tele-converter are very good indeed.
Nice and sharp wide open and the IS is a wonderful feature. This is my first IS lens and even though I thought I would never need IS, I am now sold that the IS feature is a very nice option to have. My next "L" glass will definitely have IS.
Buy this lens, you won't be sorry!!
Am I pleased? You betcha!
This is a most impressive lens. I was undecided between the Canon 400mm L or the 300mm L IS, and as I am an advocate of using quality tripods I felt that the IS would not be of great benefit to me, however, as I have recently purchased some other (shorter) L lenses with IS and have been quite impressed with them, I purchased the 300mm L IS foregoing the extra 100mm reach. This lens has not disappointed me!
I have been using it mostly for wildlife photography, and whilst it is a little short compared to the 400mm, I can hand hold it and chase the action without being encumbered by the tripod. I can also focus much closer than I would be able to with the 400. I use it with a 5D mk11 and I usually bump the ISO up to give me a minimum shutter speed of about 1/200th sec which still allows adequate DOF. When the shutter is half depressed, the image stabiliser kicks in and you can really notice the image lock in.
I have used it with a 1.4x multiplier for surfing shots, and whilst they are OK, they are a little soft to my liking. Auto focus is still rapid enough to follow the surfing action.
Used this lens with and without a 1.4 converter in Yellowstone and Grand teton national parks last week,it was used 98% for wildlife shooting and it never came off my camera.the images were sharp even with the 1.4 converter.the image stabilization on this lens made handholding this lens a piece of cake!kept it on all the time,it made taking a quick shot easy without worrying about shutter speeds.construction and quality of this lens is fantastic.the included tripod collar allows easy mounting to a tripod if needed.
This lens first attracted my eye by all the great reviews i have been reading on the web. Im into wildlife/sports photography in my spare time and i thought this lens would be great. The focus searches a a lot in low light, i mean dont even try in low light conditions. I have had some problems outside where the lens is unable to focus.
When this lens does focus properly, the images are tac sharp! like a razor blade. It has nice bokeh!
Just the Best All Around!
Macro to the moon; The sharpest,sturdy,quick,This lens for the money is the best IMO!! some call it noisey what the hell im taking pictures not trying to sneak upon Bigfoot!! I have a 400 5.6 and its just as sharp and I have to put the 400 on a tripod and the 300 I dont! I never use the 400 anymore because i rather have the 300 on!! I am going to sell the 400! Its just the best all around lens in my book?
Great lens for the money
Couldn't talk the wife into letting me get the 2.8 right now but I'm really happy with the results of this lens right out of box. Personally I'd like to see the lens hood built into all lenses like the 300f4 but that's another story. I've noticed on the Canon lens chart that they show this lens to be discontinued but I went ahead and pulled the trigger and in my humble opinion you get alot of bang of the buck with this lens
Great lens for the $.
I bought this lens to get a little more "reach" than my 24x105 was able to give .
The lens takes good bird pics and also does well taking butterfly /flower pictures.
Cropping pictures out of a 5D mk2 is not a problem to get a 1 to 1 image.
A lens cradle is a must when treking through the woods as it is a bit heavy,
But it does a great job
Awsome lens for the price !!!
The 300mm lens is crisp and fast, I am a sports photographer and recomend you check out this lens. It has 100mm more reach than my 70-200 and when on my Canon 50D bodies it,s reach is 480mm. The only disadvantage to this lens is you cant shoot in low light, but at f4.0 the lens is awsome and great deal for the price when you are on a budget.
A super compromise
There has been much debate of the pros and cons of this lens vs the non-IS version. I have had both and I can tell you that there is no appreciable difference until you get into the lower shutter speeds and then this lens pulls away quickly. Hand holdable down to 1/125 sec, sharp pictures 1/4 the weight of the 300 F2.8 and 1/4 the price... 'nuff said
Best Buy in Prime Lens you will find
Tack sharp, lightweight and well designed, Canon's 300 4 IS will not disapoint. On a digital crop body the 1.6 conversion will give you 480mm that can be handheld due to the IS when conditions are extreme and you can't use a tripod. It can be matched with Canon's 1.4x converter to give you 670mm and still retain its Auto Focus and IS. Overall a great lens
