The 35 1.4 should be a killer if it includes the stated optimization software. There is a writeup in the Nikon forum about this. It's similar to Focal I guess but the lens has a programmable chip that can be user calibrated to cover all distances, firmware upgrades etc.. This should cover the focus issues.

That is really cool. If successful, could we see something similar from Canon and Nikon?


I disagree. "Cool" would be them shipping lenses that consistently and accurately autofocus. This is them throwing in the towel and passing on the burden to the end user.

I find myself wondering how easy it will be to return these lenses on the basis of poor AF performance. Will Sigma force users through endless "recalibrations" before accepting a return, and maybe even attempt to shift blame to the owners - "Well we gave you a full calibration suite, its not our fault you can't make it work...."



Cool would also be cameras that don't need MA to get the most out of the equipment and both camera and lens come perfect every time right out of the box...right?

Is that really too much to ask for when you spend several thousand dollars on a camera and lens? You don't, for example, buy a new car and have to tune the engine yourself to get correct power and fuel efficiency. We have just been conditioned to put up with less when we buy electronics - 25 years ago if you bought a TV or VCR that didn't work you took it back to the shop. Now you download a driver or some form of software fudge that "fixes" the problem. In reality its just the manufacturer sending out an unfinished product and letting the customer beta test.

Back the main point though - the problem with Sigma lenses (on Canon bodies at least) isn't really just a simple MA type adjustment. Its the AF being generally unreliable. I know i tried very hard to buy a 50mm f/1.4 a couple of years ago - i walked into the shop with every intention of buying one, tested 4 and walked out with a Canon instead. Of 4 lenses, none would AF consistently. This is Sigma's problem, not mine, and i think selling lenses with the software to pseudo-fix a fundamental design problem and dressing it up as a great new feature is very similar to Tom Sawyer convincing passersby to pay to paint his fence for him....

Of course i could be wrong, and Sigma may actually have sorted out their AF problems. If so, i might well join the line to buy one of these lenses. I am currently eyeing up the Samyang 35mm and an equivalent with AF would be nice.

There are so many Internet photo forum myths.

If you're spending that kind of money (several thousand on one body and one lens as you say), yes, you should be getting accurate focus, but even with Canon body with Canon lenses, there is sometimes a need for MA or recalibration of body and lens by the manufacturer.

Do you get the stated MPG on the sticker? Probably not. Have dynoed your car? You're probably not actually getting the exact stated HP/torque at the exact stated RPM. You're just happy with the the performance and fuel efficiency so long as it's not grossly off. Of course, there have been instances where things got so bad that the EPA had to step in and this applied to many car manufacturers, most recently Hyundai and Kia.

Granted this Sigma/Stigma issue was very legitimate, I personally feel in the last couple years (new finish), they've done pretty good as far as AF accuracy and speed go. I was really reluctant at first to buy the 30mm 1.4 for APS-C, but that turned out to be great. To be honest, even Canon's own lenses sometimes need to be calibrated, I've had misfocusing Canon lenses only.

I really hope the personal micro adjust turns out as well as everyone is expecting right now. I personally don't own a body with MA, and so when I have a lens that doesn't accurately AF, I have to send it into the manufacturer (2 Canons, 0 Sigmas). Being able to take care of this on my own (saving time and money), I would gladly do. I love the fact that my AF confirm chips on my manual focus lenses can be MA'd on the chip. BTW, the Samyang 35mm 1.4 is wonderful, I love it on my 5Dc.

I suspect if you checked the car forum there would be forum members bashing the car companies.
guess that is human nature


I am thankful we have Sigma. The competition is good and the more affordable lenses are welcome.

Canon put the MA feature into their bodies, they did not do this for the sake of third party lens manufacturers..

Basically what we are seeing if this holds up in the real world, the 35L will no longer be as desirable IMO and hard to justify other than maybe for build.


That was Canon's plan all along. They will now be forced to introduce a diamond sharp 35mm f/1.4L II for a bargain price of $2,999!


I am sooo glad that I can keep and will continue to use my 35/1.4 and 24-70/2.8 (both version I)!

Thank you, Fred. One is broken. The others convince me. The bridge , babyear and "glas in glas" look amazing, the others show a superb bokeh!!!

Thanks for these early samples. I can't wait to see samples on FF.

Sigma can really do nice bokeh - I have the 50 and 8 f/14 and love them. The glass in glass shot is just superb. Lens appears sharp wide open.

If 3rd party lens manufacturers can sort out their AF and QC, there really isn't any valid reason to stick with OEM lenses with this level of image quality. That would be great for us too, as Canon/Nikon would then have to lower the price of their lenses.

Here are some full frame (5D and 1Dx) examples from the new sigma 35mm:

Can't read the text, but the photo's speak for themselves. I think they look great.
Sigma seems to been moving up and up.

What I want is a lens that's as sharp, if not sharper than my 35 f2, only at f/1.4 with fast, reliable auto focus, and build to stand up to occassional bumps.

The issue is that the prices of the amateur lenses is reaching the bottom end of the L lenses. Many of the amateur lenses could benefit from an update such as 50mm 1.4, 35mm f2 (older one), 28mm 1.8 and probably 85mm 1.8, but the prices of the updates are so high that people like me need to wait even longer to get lenses that don't cost an arm and a leg.


I agree that they are too expensive. But remember that all those lenses are 20+ years old. Then you will not see a 10-20-30% increasy in the price if a new and much improved version is made. It will be a lot more


If the engineering and production process didn't actually improve over those 20 years, then I definitely agree. But somehow I can't believe that it stayed the same since 1990s... I think the "wishful milking" is a considerable part of the price for the the latest Canon ring-USM lens offerings.

Yeah they do. They seem to focus on different things than Canon and Nikon. For example on the 35, long. CA. Some of their other lenses are like this as well. The 105 OS and 150 OS macro are the same way (compare to the 100L which is amazing but focuses on different things so it has some long. CA.) The 120-300 OS is the same way, almost perfectly corrected in that regard leading to amazing rendering.
