Hi guys

First post after just getting my K10d, I am interested in wildlife and motorsport and would like a zoom lense. Having spent all my money on the camera I have a very limited budget. I have been looking at the following

Sigma 70-300 F4-5.6 DG Macro
Tamron AF 70-300 F4-5.6 DI LD Macro

Both can be bought for around 100, not sure if the Sigma is auto focus ( which I need ).
Does anyone have any personal info on either of the above or can recomend and alternative ?

Nice forum, might have to enter some of the photo comps. once I figure out what all the buttons do !!!!!!

Hi Daz and welcome to the forum.
The Sigma is definately AF

I have been considering one of these also, and have read good reviews on both, so i would like to know also which one is considered better. I suspect they are pretty much identical to each other.

Thanks for the welcolm

I have the Digital SLR User mag ( dec 2007 ), it has a small review on both lesnses the Tamron appears to get a slightly better review although both complain about soft images when at full 300mm. I was just wondering if anyone had thier own personal views.

Cheers

Hi,
Welcome to the forum.
With both lenses you can't go wrong. Exelent value for money.
They are both autofocus. A lot of forum members use the tamron. And are very happy about it. The Sigma also has a APO version who is a bit more expensive. About 160 GBP new. The Tamron is about 104 GBP.
If you go for the Sigma i advise you to go for the APO version. It is worth the extra cash. Both zooms have a good close focus capability (1:2) at 180mm to 300mm. Both zooms are goiing soft from 200 mm to 300mm.
The Tamron is a bit lighter. Both have metal bayonet mounts. Anyway.....,you will be happy with both of them.
good luck,
Martin.
Best regards,

Martin.

Thanks Martin.
The Sigma APO version has the red trim around the top of the Barrel and the non APO has a yellow trim if i am not mistaken

The lens hood on the Tamron doesn't have a slot for putting your finger in for rotating a circular polarising filter, which is a pain. Otherwise, I like it!

I don't think this is right,Clarky But i could be wrong. I was under the impression the old APO version had a yellow rim, and the new silky smooth finish APO one has the red rim. The non Apo version doesn't come with a rim. But again, i won't bet any money on this statement

Welcome to the forum! You're unlikely to find anyone who has both lenses and can therefore do a back-to-back comparison. I have the Tamron and I'm happy enough with it, it's not perfect but it's pretty good for the money. If I had the Sigma I'm sure I'd be happy with that as well.

I think the final choice will come down to what your local camera shop has in stock and/or which you can get the best deal on.

Good luck!

I have been happy with the Sigma 70 -300 APO. The 'macro' facility is quite useful. I try to avoid going beyond 260mm: it does get softer from then on. It was the lens - on a K10D - that I used for the shot that got to the final 10 wildlife entries in the recent Wanderlust competition, so it can get good results. Didn't get a prize, but very happy to have got to the final 10.

out of those two I would go for the Tamron,

if a few extra quid can be found, give consideration to the Sigma APO.
you don't have to be mad to post here



but it does help

Out of those two I did go for the Tamron.

I was impressed by the reviews, and it's a bit lighter. It was also a lot cheaper at the time I bought one - 60 quid! (from tekno.co.uk - who sadly have now been swallowed up and squashed by Jessops).

Even at a hundred quid it's remarkably good value for money - thanks to the combination of Japanese design and Chinese manufacture.
