As mentioned the 300mm F4 is a cracker of a lens for the money and works well with a 1.4 TC
Oh and the tripod mount (same as the 300mm f/4 AF-S) is reported to be crap, but nothing that can't be sorted by jamming an asthma inhaler between it and the lens...

Sigma do though Stewart.......![]()

Why? Nikon had AF-S technology when this lens was introduced, and chose not to use it. The Canon 100-400L was already on the market, and Nikon chose not to try to emulate it. What's changed since then?PS..........Nikon must surely be bringing out a newer,better,faster version of this lens...........:shrug:
Nikon just don't have anything to compete with Canon's three telephotos (300mm f/4 L IS, 100-400mm L IS, 400mm f/5.6 L).

I don't think that's very helpful. We can't all afford £3000+ for a 200-400mm f/4 VR, or a 500mm f/4 VR, or whatever you consider to be serious bird glass. Does that mean we should all just give up and leave bird photography to the people who can?who wants f/5.6 max app ?
..... the 100-400 might be popular in Canon circles, but its still a slow lens, fast af is no good to nobody if the light is poop
..... Serious bird glass is expensive/end
..... I don't consider either the 100-400 or the 80-400 to be serious bird glass, f5.6 is not where you want to be in the British climate.
I'm not trying to rent a lens. I'm trying to help the OP who asked about the 80-400 VR. I'm not sure what you're trying to achieve with your negative and unhelpful post, but I resent your implication.I'm sure you'd like to recommend a Nikon version for rental, but not everyone rents lenses for a living.

So what do you suggest, another round of Nikon bashing and then a manufacturer change to Canon....very helpful and positive.

....especially when the op doesn't specify what the lens is to be used for particularly.
I sincerely don't mean to imply anything, other than that I feel you're frustration, at not being able to offer what you want to offer.

This whole discussion is meaningless in this context. lens stabilisation is an aid, nothing more.
TBH, its the long end of the zoom togethere with the focusing speed that I'm more bothered about at the moment as its main use will be for wildlife and motorsportIt'll still be about 5x... let just say that without the DX crop factor on FX bodies, a bit more length is useful so you can infer what you like from that![]()
am I understanding you correctly here? - are you saying the replacement is going to be for the DX format? I'm very happy with my D300, but I'm not ruling out upgrading again later, so I'm thinking I'd be better off only getting lenses that would be OK with full frame cameras....
