Canon 70-250 IS vs 70-300 IS lens

Found 29th Jan 2014
Hiya all,

I'm looking to buy a new lens, I would love to say my budget would push to an L series but it doesn't sadly.

My choice is between a:

Canon EF 70-300mm f/4.0-5.6 IS USM Lens


Canon EF-S 55-250mm f/4-5.6 IS II Lens

It's for a crop sensor 600d & I'm aware the EF 300mm will give me a cropped zoom of 460mm-ish, while the 250mm is just that being a EF-S.

If they were both EF-S & it was just a difference of 50mm I would favour the 250mm but does the 300mm justify the extra price? Is it a far better lens or is it merely just a longer focal length?

You're confused about the ef/efs thing.

Both would be the equivalent 1.6x on the crop sensor. You wouldn't be able to use the efs on a full frame body if you upgraded.

I've only heard good things about the 55-250.

What would you be using it for?
Thanks, I knew one was x1.6 I didn't realise both fittings were.

Mostly Travel & Nature (birds more than macro), with the occasional sport shot.

The 70-300 is a lovely lens, colour reproduction is very good.
I own the 55 -250, happy for the price , read some reviews on dpreview

Internet opinion suggests that broadly they're similar in image quality. Full frame compatibility is basically the only reason for the price difference - well, that and the USM focussing but to be honest the 55-250 is no slouch.

I'd go for the 55-250 and worry about full frame lenses when you have a full frame camera.
