Hi everyone, need some advise please, just purchased a Canon 450, as I wanted a camera for a hoby (retirement just round the corner) I now want to buy a lens for wildlife ect. looking at 300m but been told that the Sigma 18/200 os and the Canon efs 55/250 IS, will give me greater voom with my camera, don't understand this, can anyone please explain or advise on a lens, under £300.00:
 
hI dontwanadoo and welcome ...if you go to talk equipment theres a wealth of knowledge in there that can help you out:thumbs::thumbs::thumbs:
 
Hi dontwanadoo,
This is probably going to take you a bit of googling and research to fully understand but I may be able to offer enough advice to get you going.

DSLRS effectively have 2 kinds of sensor, Full Frame & Crop.
Yours, like mine, has a cropped sensor.
Take a look at this link.
If my understanding is correct, the crop factor will magnify the image by that amount. Your body has a crop factor or 1.6 (I think).

In short, any zoom lens you attach to a body with a cropped sensor will have a slightly longer reach than if it was attached to a full from body.

Some one will come along with a load of maths in a moment and make me look really stupid, but that should get you going.
 
I had/have the Sigma 18-200 OS (its up for sale elsewhere) its not a bad lens but i ended up getting the Canon 70-300 IS for the extra reach and prefer it, however i still want a longer lens.

This doesn't make any sense at all. Basically, the longer the focal length, the closer the wildlife will seem. A 300mm lens will make your animals or birds larger in the frame than a 250mm or 200mm lens.

This page on the Tamron web site allows you to see the effects of different focal lengths.

For wildlife, most people would recommend 300mm or more. There are lots of 70-300mm zoom lenses; the Sigma 70-300mm f/4-5.6 APO DG MACRO seems to be highly regarded and it's only about £150. (The APO in the name is important though; there's a cheaper version without it which is much less good.) The Canon EF-S 55-250mm f4-5.6 IS is also considered to be very good value; it's only 250mm but does offer you IS.

(I should stress that I don't have any personal experience of either of these - just passing on what I've heard elsewhere.)
 
what sort of wildlife do you want to capture?
 
The other thing to remember is that whilst a zoom lens gives great flexibility, generally they are never quite as sharp as a prime lens. (there are probably a few exceptions though!!) However, if the critter comes close, then a prime may be too long! If you are new to wildlife photography, then a zoom is probably a good idea, as it can be used for other things too. If you get seriously bitten by the bug, then you can move up to primes.

Personally, I'd hire one of each and try them out first.

Oh, and welcome to TP!!

True. But then you just can't get any cheap telephoto primes, whereas cheap telephoto zooms are very common.

Canon's cheapest telephoto primes are:
* EF 200mm f/2.8 L II = about £650
* EF 400mm f/5.6 L = about £1100
* EF 300mm f/4 L IS = about £1200

Sigma don't seem to make any telephoto primes cheaper than the 300mm f/2.8 EX DG, which is about £2000.
 
Thanks for all your help, things are looking a little clearer now, in answer to what wildlife I want to capture? I should have said wildlife and anything that is of interest, I travel alot and take my camera with me, I'm up in Scotland Friday, may visit Falkirk Wheel, Sunday down south, going to have a couple of hours looking at the Red Kites around Oxford just off the M40, so anything that of interest, but I do require a longer lens.
thanks again
