nothing wrong with them, cheap and good for a poor man like me
I have Tokina 17mm, Tokina 28-70mm and Tokina 80-200mm
They have never let me down before
If someone happens to be using the Sigma body, then Sigma lens should be 1st party, right?clive said:duh..everybody knows that sigma is not original :bsmilie:
or whatever lah...just buy a lens u like n shoot happily
Well, Sigma was originally a 3rd party lenses maker, then they started to make their own bodies with their own mount. Tokina and Tamron remained as just 3rd party lens maker.AReality said:So U mean canon body can use sigma lenses, sigma body cannot use canon lenses? :think:
Izzit because sigma body has it's own type of mount?
It is true. Many years ago, I had a Practica BX body and was using the Carl Zeiss Jena lenses and compared the 135/2.8 with Nikon's and I found that once the picture is blown up, the resolution is terrible and some regions come out more grainy than the same shot with the Nikon.F34r said:it is said that the difference between 1st party and 3rd party lens can be pretty distinct when a picture is blown up. heard it gets more grainy, and its not the film thats making it grainy. not sure how true is it though..
There were some 'news' some time back that to lower manufacturing costs, Leica contracted Sigma to manufacture some of their lenses. By doing so, Sigma has obtained their technology and some time later, Sigma came up with their own EX series lenses. Before this, Tokina was reputed to have better lenses among the 3 better known 3rd party lens makers. Tamron lenses were known to have it's multicoating easily peeled off.kraterz said:From my experience with third party lenses, most of them have not performed as well as my OEM lenses. I've used some Sigmas, a Tamron and a Tokina. The only 3rd party lens which comes anywhere close to my OEM lenses is the Tamron 90/2.8 macro. I've not had excellent results with the Sigma 28-70/2.8, 15-30 EX DG and some Tokina zooms. They are OK but my OEM lenses are just better, AND they offer USM.

I don't see why not. By making lenses for Leica, you would be limiting the number of lenses to the number of Leica users. By making lenses for Canon, Nikon, Minolta and their own SD-series DSLR, it's a vast market out there. Once you set up the line, you just need to churn lenses. In fact the economies works better. However, I am sure the optics are not ground to the perfection that Leica would have required, but sufficient to meet the needs of DSLR users.sriram said:There were some stories that the leica 28-70 was made by sigma, but under much stricter QC/mfg tolerances. I've also come across and heard many stories that these sigma made lenses sucked! Whether or not they sucked, I don't see how sigma would be able to make their EX lenses to the same strict spec but at a much lower cost. The economies of scale just don't work that way, unless they sell a bajillion lenses.

sriram said:I'd never spend thousands on something like the sigma 300-800, 120-300 etc not knowing whether it will work on a new camera 2 yrs from now, and suppose they say it's not supported any more, that's a $10,000 paperweight. If you think sigma's newer lenses are free from compatibility problems, just look at the number of new lenses which misbehave with the D200. No thanks.
