Thinking of buying the sort list below

Canon 40D body only.
How good is the build in sensor cleaning?
What's the ISO range?
Is it worth stepping from the 30D or waiting for the 50D if it's on the cards?


Canon 28-300 L IS USM Lens
camera?Has anyone got this lens?
If so what do you think of it?
I haven't got that many Canon lenses as I tend to go for the Sigma range but I like the look of this lens as it has a large scope for range plus it would be my first L lens.
Or would I be off going for something else in the Canon L range, if that being the case which one and why?

I'm happy to invest the money but want to get the right options, thank you in advance for all advice.

What are you shooting mainly Davey? I notice some Car/motor events but is that your main subject?

Mainly motorsport and some airshows and a bit of wildlife when I can sit still long enough lol. On thinking more deeply yes it would be nice to have some L glass but I think in the long I'll save me cash for now and have a rethink later in the year

The 40D is a very good camera, but the 30D is no slouch either. The new sensor cleaning feature is handy to have but it won't work wonders, you can still get bits of dirt stuck to the sensor. TBH I think you'd be better waiting for the 50D (sometime next year by the looks of it) or maybe a 2nd hand 1D mk.II/n as I wouldn't say there's a huge difference between the results you'd get from the 30D and 40D.

I don't own one but the 28-300 L IS is regarded as a very good quality all in one lens. However as your interested in motorsport, airshows and wildlife and looking at your kit list I think you'd be better off sticking with what you've got (if what you've got are the f/2.8 and f/4 versions of the Sigma 70-200 and 100-300 respectivly, they're great lenses and worth keeping). If you have the 100-300 f/4 it might be worth swopping the 2x t-con for a 1.4x t-con to give you some extra length for the animals but allow you to keep autofocus.

If you really want to go L I'd say your 17-85 IS would be the first lens to change, possibly for something like the EF 24-105 L IS.

Well I've spent a little bit of money........
Iain I've taken your advice a bought the Sigma 1.4 TC thanks for your advice.
I've also gone for the Sigma 18-125 as a replacement for the Canon 17-85 as the Sigma gives me a little more length and is a stop faster than the Canon. Finally I've gone for the Sigma 150-500 for the extra length and HSM to replace my 80-400.

I have to admit I'm happy with using the Sigma lenses as I know where I am with them and never had any problems so going on the "If it an't broke don't fix it" saying....

Please let us know what you think of that 150-500 lens ( apart from the fact that it is heavy ) I am thinking about buying one soon. I think that the optical stabilisation will be a big help.

Where did you get that lens from, I will probably use Onestop in HK but would look at a good UK source as well.
