Photo Forum / General Photo Topics / Australian Photography / October 2005Sigma Lenses
Anyone have any experience with getting sigma lens CPU's upgraded to sort compatability problems? My Sigma 17-35 HSM EX used to work fine on my EOS 50 but on my EOS 30 & EOS 350D it doesn't focus (although the focus indicator beeps when focus is achieved while focusing manually). Does it fix the problem, does it cost money or do Sigma just do it free? Whats the go Also is the Sigma 70-200 F2.8 EX a good alternative to the Canon white lens? Thanks. CRK would be the people to ask (big LOL!!!) The Sigma is a lens a tad over $1,100... compared to a $2,600 non IS lens or a $4,000 IS lens, it holds up very well. T. AAAHhh Kennedy's can't live with them and you can't live with them, the bastards. Saddest thing is that they are the importers for Pentax :-( > CRK would be the people to ask (big LOL!!!) > > The Sigma is a lens a tad over $1,100... compared to a $2,600 non IS > lens or a $4,000 IS lens, it holds up very well. > > T. > AAAHhh Kennedy's can't live with them and you can't live with them, the > bastards.

Pentax might be a really popular camera in Australia if Kennedy hadn't put God awful glass on them and created the impression Sigma and Pentax were like Olympus and Zuiko. I'd be a lot more tolerant of them if they hadn't taken 3 weeks to tell me my 3 day old Sigma lens wasn't faulty when it focused forward of the point by many, many inches. If you need any Sigma lens work done, send it back to the factory. It's not as difficult as it sounds.  SignatureDouglas...

Must say that I have been lucky, the couple of Sigma lenses that I have tested focus perfectly, can't ask for too much more at the price. >> AAAHhh Kennedy's can't live with them and you can't live with them, >> the bastards.

There were problems with the compatibility of TOKINA lens as well - its not isolated to just SIGMA lenses. ( I'm talking higher end models as well) My philosophy is to buy glass branded by the camera maker - seems to always work without compatibility problems. rm >>> AAAHhh Kennedy's can't live with them and you can't live with them, >>> the bastards.

Work out the rate of deprecation for a lens then make a comparison and tell me if its worth having to put up with marginal quality. I know that I would be pissed off if I bought a crap lens and needed to send it off sooner rather than later. I have bought third party lenses and personally know of third party lenses which should never have been sold. These include Sigma, Tamron, Vivitar and Tokina just to name the main players. >>>> AAAHhh Kennedy's can't live with them and you can't live with them, >>>> the bastards.

I seem to recall the footer on your posts mentioning something about ignoring specs and looking at results........ the camera is just a light tight box..... the lens on the other hand... >> Yeeeep.

Just to set your mind at rest Kosh... I have 6x the value of cameras in lenses. I was aiming my remark at those who struggle to pay $1000 or so for a camera and then have to contemplate paying 1.5 times that again for a lens, just to take pictures as good as we did in the 70's and 80's with lenses which cost a few hundred dollars. Some Sigma lenses on some cameras are remarkably good value and don't carry the absurd burden of artificially high prices Canon lenses do. SignatureDouglas...

Tokina is a very good compromise for Nikon users - Tokina build most of the Nikon lenses using Nikkor glass, and then build their own using Hoya glass. Very compatible with Nikon kit - can't speak for other brands. I suppose there'll always be an issue with third-party lenses trying to integrate 100% with the camera. They'll get it nearly right nearly all of the time, except when you want absolute perfection. If you're doing commercial photography, stick with the OEM/branded kit. If you're a hobbyist or semi-pro, then you take educated and economic choices as to what you may compromise with. I use both Tokina and Nikkor/Nikon glass - happy with both, but the Nikkor is sharper. Forget what camera you use, if you shoot through coke bottles you'll get a crap image. Glass is everything. Cheers, Andrew. > I suppose there'll always be an issue with third-party lenses trying to > integrate 100% with the camera.

Yes I agree with in principle with the idea of getting branded lenses but I am considering Sigma EX glass (70-200 or 100-300) for 3 reasons - one all the reviews I've read from users are nearly all saying it compares to L lens image quality, they are a heck of a lot cheaper which is a real plus when you are an amateur on a budget like myself, and they are black not the awfully conspicious white of most L glass. Having said that if I don't get satisfactory resolution of the comatability problems I'm having with my 17-35 I might still have to think twice about sigma lenses. I bought the lens from a Hong Kong ebayer by the way - will that afftect what CRK will do for me? Cheers CRK would do very little for you if you bought a Sigma locally. So I guess they would rise to the occasion and doing nothing for you in the case of a HK Sigma. Back to the 70-200 though... there is nothing at all wrong with the Sigma EX version. Even with a 5D, I'd be inclined to save your duckets and go Sigma. T. >> I suppose there'll always be an issue with third-party lenses trying to >> integrate 100% with the camera.

AF for example is prob just as important depending on the way that you intend to use the lens..... what is the good of a opticaly good lens if it won't focus properly? A few eg:..... I tried the tokina 70-200 2.8 at one point and it was as sharp as a tack, but it would never get accurate focus until the second semi-press of the shutter button, plus in AF tracking mode it was not fast enough. This was hopeless for me as it was intention to use the lens for sport. On the other hand, I have a Sigma 10-20 for my wide FOV and I have found it to provide better sharpness edge to edge than the Canon 10-22. I also have the Tamron 90mm 2.8 Macro... this lens is every bit as sharp as Canon's famed 100mm Macro, but the AF is slooooow, but in this case it is not as issue for me as I manual focus my macro anyway. So in a nutshell, look at the whole package and how you intend to use it or you may well be dissappointed when it comes to the overall experience of using a particular lens. >>I suppose there'll always be an issue with third-party lenses trying to >>integrate 100% with the camera.

Purple is a nice enough colour - except when it edges all your best shots! SignatureDouglas... Specifications are good to read but When it comes to judging Digital Cameras...

Take as an example the E series Nikon lenses at the time. Now Nikon still have cheaper range lenses available with good glass. I am speaking of the short zoom 2.8 Tokina that was not compatible between the F100 and F5 and that's too close for it not to be correct. This may now have been corrected in later versions . r | Tokina is a very good compromise for Nikon users - Tokina build most of | the Nikon lenses using Nikkor glass, and then build their own using Hoya | glass.

Glass is everything. http://www.marktucker.com/plungercam/ I can't agree - film/sensor res can be so low, coke bottle glass would suffice often. then there's the issue of knowing what you can do with your gear -hence the reason AA was envious of Weston. Weston had junk, AA had the good stuff, Weston CHOSE to keep using his old 'junk' because he knew what it was good for. glass is certainly part of the equation, but I think the plungercam images above illustrate what *can* be done with 'junk' k | My philosophy is to buy glass branded by the camera maker - seems to | always work without compatibility problems. hehehe can I say 'Nikon' ;-) k > Anyone have any experience with getting sigma lens CPU's upgraded to sort > compatability problems?

If this is you rproblems, CRK were fixing it for a period free of charge... not sure what they are doin gnow. Best to contact their "Customer Service" (LOL) department. they are not even bringing in the entire Optio range... da scum kosh M Wrote: > Also is the Sigma 70-200 F2.8 EX a good alternative to the Canon white > lens? > > Thanks. The Sigma has tested slightly sharper from wide open until around f8.0 than the equivalent Canon L lens at 200mm. Sounds like a good alternative to me. bazz. Signaturesir_bazz |
