Canon EF 70-300mm f/4-5.6L IS USM UD Telephoto Zoom Lens for Canon EOS SLR Cameras – Review:
LIGHTWEIGHT AND GOOD PERFORMANCE!
I’ve been shooting for about 4yrs now and while I’m definitely not a super seasoned professional, I can say that I have ample experience to offer some good insight about the equipment. I’ve had a 40D, 50D and am now shooting primarily with a full frame 5D Mark II.
One of my favorite lens is the Canon 70-200 f/2.8 L IS USM lens. I haven’t had the need or urge to upgrade to the Mark II version of this lens yet, but I have been waiting for Canon release an L zoom lens that fills the gap my 70-200 and 100-400 so that I don’t have to carry both… Anyone of these lens is already heavy enough, so to have to carry both is quite a duty in itself.
– Prior to this lens, my lens of choice for outdoor photography is my 70-200 f/2.8 lens, but the light weight, size and focal length makes me think twice before I leave the house when I only want to take one lens. If I know my destination has good lighting, I quite often take this lens over my fixed aperture lens. The added 100mm is a great add benefit within a zoom lens.
– Overall build quality is superb, as to be expected of all L-series lenses.
– Very sharp lens through almost the entire focal length. When compared to the 70-200, I do notice this lens to be a little softer wide open. Zoomed in say, past 100 or 120, the sharpness is on par w/ the 70-200.
– Shorter barrel length makes it easy to carry within a toploader case. I was happy to see that I didn’t have to buy a new case just for this lens. Again, in reference to the 70-200, I was able to re-use the toploader I used w/ that lens.
– While I still try to limit my equipment in terms of exposure to rain & water, this lens is weather sealed compared to the non-L 70-300 lens. Its added comfort in case you HAVE to shoot in the wet or if you unexpectedly get caught in the rain.
– I MUCH PREFER this lens’ twist zoom (very smooth) over the shotgun style push/pull action of the 100-400 L lens. The zoom ring is smoooth and extends/retracts effortlessly, a welcome quality for a lens of this focal length and size.
– Focus ring is also super smooth with little resistance as with most L series lens.
– I was a little disappointed to see that Canon did not include a tripod mounting ring. I understand that tripod mounts on a lens is most critical for heavy/large lens, but this is no small lens by any means and it definitely teeters on the edge of being a heavy lens. I would highly recommend getting the tripod mount for this lens so you don’t stress the mount on your camera.
– This lens is not compatible with any of Canon’s lens extenders. It would have been great to convert this 70-300 to a 98-420, but as it turns out, the rear element is very shallow in relations to the mounting treads. This is where the shorter barrel is a negative for this lens.
I would have much much preferred to have the zoom ring as the inner ring in place of where the focus ring currently is. I would have to say though, having the zoom ring on the outside/end of the lens does offer a little better balance for the lens when you zoom out (barrel extends when you zoom).
I would say, if you already have a 70-200mm L f/2.8 lens, I would heavily recommend the consideration of a 1.4x extender over the purchase of this lens. Not only do you get the benefit of getting a fixed f/4.0 zoom lens after the extender, but you can save yourself the cost of buying another lens. The caveat to this tradeoff is that, w/ a f/2.8 + 1.4x extender, the weight is significantly greater than the 70-300 lens by itself. I haven’t necessarily weighed it on a scale, but, the 70-200 f/2.8 + 1.4x extender feels about twice as heavy as the 70-300.
Using Canon provided specs, here are the weight comparisons:
70-300 f/4-5.6L IS:…………………….. 2.31 lbs
70-200 f/2.8L IS:……………………….. 3.24 lbs
70-200 f/2.8L IS + 1.4x extender:…… 3.74 lbs
Overall, I have decided on keeping this lens mainly because of the versatility and the incredibly light weight and size. I can’t wait for Canon to refine the well aged 100-400 L lens… I hope it happens soon…
