Tamron AF 70-300mm or Sigma Lens 70-300mm or Sigma 70-200mm

Howdy all.

I'm wanting to save up for some new gear, narrowed it down but i'm not sure what one to get.

My options are

to get a Sigma APO 70-200mm F2.8 II EX DG MACRO HSM

or a

70-300mm fF/4-5.6 (either the Sigma APO or the Tamron LD Di) with some filters a new bag (lowepro FP 250) and a grip

as far as the 70-300 goes, i'm caught in the middle, bit of a fan with sigma but have heard some good stuff about Tammy. heard from someone that this lense Tammy have better glass than the APO, is this true or a bit of porky pig?


I've got sofar sig 18-50 f3.5-5.6 & 28-200 f3.8.5.6 and a Takumar 70-200mm f4

any help is very much appericated,

Have a good one all.

I think it depends on the budget.

the 70-300 is a slower smaller and less expensive lens. The question really is, over the long term will you be happy with it.
You will not be able to add much of a TC to extend the range on the 70-300 because it is too slow and the AF will have difficulty.


the 70-200 F2.8 will cost you more, BUT when sigma releases the new HSM TC's later this year, you will be able to add either a 1.4X or 2X and still have a faster lens out to 400mm than the 70-300 all on its own at 300mm.

the other issue is weight. the 70-200 will be much heavier.

I have always gone for speed personally, I have the origonal APO 70-200 F2.8 EX and it is excellent with both the 1.4 and 2x TCs, and to be honest, the lens will out last the camera body,

Yea i was thinking of buying an 2xTC with the 70-200 later on, weight is not an issue, nor is size. unfortuantly i can only get one or the other.( either 70-300, bag grip and some other goodies) or a nice set of glass 70-200.

I would get the 200 in a heartbeat but i kinda need a new bag and some other stuff i could get with the 70-300.

does tamron have HSM on there 70-200? or is it still screw drive?

thanks for you support mate, really appericate it

have a good one!!

I can't answer as to backwards compatibility (i.e. screw drive support) on the HSM lenses. To be honest, I haven't got any intention of getting one, since I have had such good results with the origonal, I'll stay with it.

As someone who gone through the many phases of LBA, I will offer this advice: Get the lens you want now. It'll save you the trouble of getting it down the line. Bottom line...you're going to get the 70-200 so you might as well get it now.

I agree. You can put a 1.4 or 2x teleconverter on the 70-200mm and it will still be better than a 70-300mm (okay, might be stretching it a bit with the 2x TC but not sure). What you get is a lot more versatility and image quality, but its more expensive and heavier... and you have to wait for Sigma to upgrade their TC's for HSM support on Pentax

Love my Sigma 70-200mm that I just got. It's heavy, but it has excellent image quality, especially stopped down to f/4 or f/5.6, at which point it is prime-like.

a 2x TC is no stretch!

+1

I got mine for $950 AUD from Paxtons in Sydney CBD, and it is worth every cent.

I used it at a wedding on the weekend and am very happy with the indoor shots I was able to get.

Intend to use mine for a wedding in June as well.

Not sure if these are the sort of shots you do, but I have some studio shots with this lens here:

Would you not consider the Tamron 70-200/f2.8 also?

Yea i would and i kinda would prefer a tammy, some say the glass is just a bit better than the sig but yea it is a bit slower in the focus. I Would consider it if i knew any store that stocked it or at least had less than a 3-4month waiting period for it. best i found was that if i placed an order 2 weeks ago i might get in in Feb :S

does anyone know where i can get one before new years in Syd?

For me it came down to which one was available in Australia for a decent price (I wanted to be able to handle it and take some test shots before buying).

On this criteria, the sigma won.

I honestly think both lenses are very equal in picture IQ, focus speed and build quality.

I found the Sigma priced at $950 (it seems to have gone up in price by $300 since then - ouch!) at this place: Cheap digital cameras and camera accessories | Camera-Warehouse and Paxtons (who also had it in stock) were happy to price match.

I just noticed that Paxtons still have the Sigma advertised for $999, which is an EXCELLENT price considering the Aussie dollar, so I'd jump on that! (it works out to be only US$680 - even beats the best American prices substantially!)
