This lens is ideal for sports and wildlife photography. The newly designed optical system has one fluorite element and two UD-glass elements to obtain high resolution and high contrast. Also, the minimum focusing distance was reduced to 18 ft. (5.5m). Extender EF 2x II can be attached to increase the focal length to 1200mm while retaining AF (at the center focusing point with the EOS-1v and EOS-3).

The good news is that the goal of producing some very sharp images and high quality is capable of. The bad news is that the copy (which is 4 stars instead of 5). Not necessarily believe those who tell you that it is "good technique".
I went to 3 items before they are ever to end, which would be implemented as one waits for a lens to $ 7000 +. The first copy was obvious flaws, produces soft images lack detail, and returned to the seller. 2. The screen was a bit 'Likewise Bad chromatic aberration (even with the soft images are still missing details), and went to the factory service center in California twice. Both times, the FSC has given to me in worse shape than when he went to after preliminary contact with a Canon executive, went to my engineers Canon lenses, and I was granted a loan within 24 hours (which is not never the head of the FSC California offered). Canon executives apparently calm, I'm not so certain of their FSC.
Canon finally told mewould use the objective of finding ways to improve their production. She has offered to sponsor me as intelligent, but I was on the basis of molten metal flakes visible element content. Canon closed Send me a copy of which was first examined by their engineers. I had the sheet for 5 months and it has felt good – strong, good contrast, etc.
So, if and when you buy this objective, to gain confidence from a seller and a seller who knowsIn collaboration with you. I bought from Canoga Camera in Southern California. With the first goal, were incurred. With the second lens, I was told that I could not go back, and then had the Canon sales representative call me. The sales staff insulted (literally), I said that I knew what I was talking, said: "We're done here?" And then basically hung up on me. I was on my own, when I contacted Canon executives in New York. Luckily they were very professional and respond, but wasa lengthy trial very stressful, which is considered how much money was at stake.
Live View with 10x, which is visible shake 840 millimeters (600mm + 1.4x TC), while even if the target seems to be stable. But with IS, the results very clear.
Besides a very good sturdy tripod and tripod head that I filled excellent results using the molar Bean Bag get with 20 + pound pinto beans. This lens produces images much better than my Canon 100-400mmf/4.5-5.6 L IS. Even with a 2x TC, the results of this goal are better than my 100-400mm.
For comparison, the Canon 24-70mm f/2.8 L, 70-200 f/2.8 L IS own and 100-400 mm f/4.5-5.6 L IS. The 600 mm is my only prime number, so it should come as no surprise that performs the best of all lenses are in my collection. The 70-200 is a close second in terms of performance.
Worth the Weight! – Charlie MacPherson – United States
I have this goal for most of a year in possession, and are perfectly happy with him.
The disadvantage of this method – it is almost 12 pounds, and costs half as much as a small car.
E 'as the adoption of a child 12 pounds – when you click on a photo shoot, you have to take everywhere. We can not allow that in mind. It's too much to bear, do not want to slam around, and is always in the back of someone to steal, if you'd like. Search
But all that said, this is an incredible goal!
After a year of launch of a competitor 500 millimeters F6.4 Zoom – and poignant that it would be worth the price, I updated the Canon 600mm.
The improvement in picture quality is strong. Bokeh is superb. The F4, combined with the IS will allow me, the images that are out of reach with the goal of others. And the extra 100 mm focal length – especially in combination with Canon 1.4X Extender really tunedfills the frame, and with what you shoot.
I have it shot in extreme temperatures from 90 F-3F and over 20K images, is never the slightest problem.
The autofocus is fast and the dual-mode and it works very well.
Invest in a decent tripod and gimbal head (Manfrotto works very well at a fraction of the cost of Wimberly) and you'll be happy. Try to hand hold this beast, and will not be.
But if you thinkMovement up to this end take a keen Bird & Wildlife photographers – you will not regret it!
Big Guns! – Longhorn – Big country
This is a great lens to bring things up close and personal. Has image stabilizer that works great. Po 'on the heavy side. Propose as a worthy expense and weight.
