There were some pics taken with the 18-35 on a 5D mk II, but those images seem to have disappeared:aznable said:garyknrd said:Dumb question. will the new Sigma crop zoom work on my mark IV? I am fixing to do some traveling I hope. And only want to bring one lens for landscape and people.
is it will work, as all others DC sigma lenses; it's likely you will get an heavy vignetting at 18mm. i guess we will have more reports on this when the lens will become widely avaiable

Don't blindly recommend Canon's glass against Sigma, Tamron, Tokina, Samyang etc. - they all have some outstanding products, while having to reverse-engineer the AF communication.

The flip side is to get angry at Sigma, etc. fanboys for not being picky enough. This keeps the QC of the Sigma, etc., low; and allows Canon to keep high prices!
garyknrd said:I have two Sigma lenses. One the paint is coming off. Looks just awful. the optics are ok only compared to Canon.
The other has fair opts. I cannot sell either one? Even if the optics are good. So for me it will take more than one or two lenses for me to ever buy another Sigma lens again.

dickgrafixstop said:Technology moves on - with todays design systems there's a careful balance of optical design and coatings
formulation, computer controlled lens grinding takes the craftsmanship out of the glassworks into the NC programming lab and the secret to a quality lens is still the assembly process and the fine tuning of the unit as a whole. That's why people pay an extreme premium for Leica lenses and why neither Sigma, Tamron, and even Canon nor Nikon can build a high quality CHEAP lens. Robots can do a lot, but not the fine adjustments necessary to consistently produce high quality optics. Look at the Canon 70/75-300 in its many current models to instantly
see the difference. Even the Canon 50mm - you want good at $100, better at $400 or best at $1200 - take your
choice - and if you want a slightly different look, try a zeiss at $800.

If you think so highly of third party lenses I must ask you to buy my Tokina ATX28-70 f/2.8 which although very sharp with my EOS1n and EOS620 cameras it is a nice PAPERWEIGHT on my EOS5Dx cameras.JurijTurnsek said:This thread title made me very angry - it's Canon fanboys like OP that drive the insane Canon glass prices up. 3rd party lenses can be just as good as Canon's at fraction of the cost.

So except for a case where I bought a Zeiss lens 3rd party is not an option. PERIOD.
Everyone who tries to tell me otherwise, they have to buy my nice Tokina paperweight first.

Is it the f2.6-f2.8 version or the constant f2.8?
If it's the first one send me some pics and I will seriously consider buying it (if it is marked pro II rather than pro SV and working to specification in good order etc) if it's the constant f2.8 / SV, you are probably right about it.
