I am an amateur and not very experienced photographer who would like to start doing some wildlife photography. I currently have a Canon 350d which I tend to use with a tamron 18-250 for vesatility when out walking. I intend to upgrade to a 60D in the not too distant future, and am keen to get a greater magnification zoom to go with it. based on reviews to date I am in interested in the above two options anyone got any thoughts
I bought the Canon 100-400 back in May as an upgrade for my sigma 170-500 (the precursor to the 50-500). The main reasons being the image stabilisation and the L-series optics. I am a keen wildlife photographer in the process of turning semi-pro. The difference in handling and the quality of the images is massive. I have used this lens to take images of wild otters, birds, and dogs going around agility courses, all handheld and they come out pinsharp, not something that I could do with the sigma. I hear two criticisms (1) its a dust pump - I have had no problem at all in this regard, (2) its heavy - its bound to be, its an L-series and made of metal! (unlike the Sigma which is plastic) I actually find that the weight helps to steady it when handholding, in my opinion its easier to handhold a heavier, but balanced lens than a long lightweight lens . The image stabilisation is excellent.
I recently upgraded from the Sigma 150-500mm to the Canon F4 100-400mm. In my honest opinion the upgrade was well worth it - the image quality is much sharper, especially at the zoom end. My reason for upgrading was after I had used the Sigma for video on my 7D, it just wasn't sharp enough and the colours weren't as vivid as I'd liked. With the Canon, these problems are no longer there. It really is worth the extra few £'s. Good Luck
You don't mention your budget , Vid , but I would put in a word for the Sigma 120 - 400 mm zoom, I've recently bouight one , and it seems to me an excellent lens , very sharp , stabilised , and I'm told by a semi-pro who has used both that it is at least as good as the Canon , and of course at half the price . and the price includes lens hood and case .
Thanks Ted, actually this is somewhat out of date now.. in the end I went for the Canon 70-300L due to its more compact size (I plan to take it on a tour to Vietnam later this year) and I have been delighted with the results so far. I will probably get a bigger zoom at some point in the future but not for a year or so... I notice that the Sigma you refer to has been getting rave reviews in a lot of the magazines.. many thanks, Vid
