To reduce the overall weight and enhance portability, the lens barrel and many other exterior parts use a magnesium-alloy. Also, the detachable tripod collar revolves smoothly and locks securely.

Pros: It's a 300mm f2.8, nuff said
Cons: 300mm f2.8's are expensive

I've been lusting after one of these for around 18 months and sort of took the plunge two weeks ago. More on this later.

When you start paying in excess of £2K for a lens, comments like image and build quality should be almost pointless though it is reassuring to know you are getting a quality product.

In use the lens is quite big and at 2.5 Kg a reasonable weight. If you've come from consumer grade lenses then this could be quite a shock. I personally didn't have a problem with the size and like 1 series bodies, the bulk gives you something solid to get a firm grip on. They're obviously also large and white so not particularly stealthy. If you're toting one around zoos etc, you will get looks and comments.

Here's one next to my Canon 300mm f4L

I found I could get away with shots as slow as around 1/100th with the IS turned on. Stabilisation should be practically compulsory with lenses this size though of course it is of limited use for fast moving sports action.

However one downside of the size and cost is you become paranoid about damaging them. You'll probably find you need to ramp up your spatial awareness and not catch it on anything. Pros who get this stuff as part of their job probably aren't quite so fussed which is why you often see some quite battered looking kit.

Image Quality

Is fantastic, full stop, period, the end. Any duff shots are likely to be down to the paper thin dof wide open and shaky hands / dodgy technique of the user. You will need to (re)learn good shooting technique with this sort of kit.

Here's an unedited example at f2.8 (excuse the poor framing)

And here's one with a Canon 1.4 extender, 420mm @ f4.5

On the original at 100%, you can see the fine hairs in the nostrils .

At the beginning I said "sort of". The high cost of these lenses isn't to be taken lightly.

I found one second hand for a relatively sensible price and took the plunge. Unfortunately the focus wasn't quite right and servo tracking a rugby tournament produced a high fail rate. Now the seller was very reasonable about things and said he would fund it going to Canon. I however decided that I didn't want to go through these hoops and returned it.

The one I'm currently hiring is totally spot on .

In conclusion the lens is all I expected and wanted it to be, but the cost is the obvious stumbling block. Notwithstanding this and in light of the experience of my second hand purchase, I would buy new and get a years warranty. Trouble is, I now have to justify the extra expense
