New Sigma 35mm f/1.4 HSM DG

Day 3 with my lens and mine is front focusing pretty badly too.

I currently have +6 dialed in. At close distance it seems to do the trick, further away it'll ff...

Here's an example, this is cropped so I wasn't as close as the photo looks. You can clearly see the little black and white bow on her tee being sharp.

Front focusing example by Kinson C | Photography, on Flickr

Ok. I see you have a logo "Kinson C Photography." If your going to shoot an event as a paid professional or as a sideline as a semi professional will you trust your S35? Your next copy will you trust it too?? I found in dynamic lighting situations is where Sigma rears its ugly random oof AF issues. Hard to explain clients you wanted to save money on a sigma instead of a 35L. Landing the shot with excellent composition is equally as important on focusing on the subject :P

So far some have called me a Sigma "hater". Of all of my Sigma prime lenses I've purchased I've never had a solid performer.


This random focusing issues is why I am vocal about my personal tests with the Sigma primes. The AF issues are quite real and not over blown Internet talk.

I can see people quietly shifting to a different canon lens after all this excitement blows over. Sigma still cant fix the high percentages of sigmadud 50mm af issues "BUT" maybe there's a glimmer of hope with this "new tech" design of the Sig 35mm.

I only get bad misses due to user error. So far I've been extremely pleased with my canon lenses when accuracy is concerned.

sounds like thats the sigma 30 not the new sigma 35. the sigma 30mm is for crop cameras only.

Well, i don't think the salesman is idiot to not know the difference between 35 and 30mm, i called another store and they will give me the price later as they don't have it in their list or stock, once they get it they will call me and tell me the price, but if it will be in that range of $400-500, is it a good deal then?

If you take a picture on a target 100 feet away with a 35mm prime, you can't really expect the outcome would be just as sharp as a picture taken with a 70-200, right ?

I wouldn't necessarily expect it to be as sharp maybe, and that's fine, but i would expect it to focus at 100 feet, not 50 feet., which is the issue here...

I have had my S35 for about a month now and all is good. At first I thought I might have a problem but it was the focus point in the 7D. The top left corner is the center point of where the focus really is. Just did a test inside at 30' and my LiveView manual focus was the same as the auto focus

For what its worth my serial number 500016xx.

THink environmental portraits in low light. You have all seen dankanta's work like this. He almost always shoots wide open.

He is shooting 135mm not 35mm. With 35mm and subject far away it will be small speck IMHO in the environment. Typical 35mm env shots subject is within 10 feet.

I'm sorry I said it sounds like you are a "sigma hater", but it was is the same sentence as I was saying you made a good point. I still think you make very good points especially from the professional standpoint of reliability. My next one better be on the money as I really want to love the lens. I had a 50 and a 30 that were great. No worries with either of them. I totally would have trusted them in any situation.

No, just take a look that the last post in the 35L thread. It was posted 10 hours ago by Dakanta. I don't have a camera with me to check, but my guess is it was shot 15-20ft away and then cropped a bit. I have seen a ton more by him with the 35l that are even further out. My lens would have been all over the place at those distances.

Edit: A two second search in the 35l thread found this example by dankata....this was not taken at 10 ft! It was shot at 1.4

What's the problem exactly? I'm stuck at home (worst weather in years in this country) and I've got one copy of this lens I could test for you.

is he an idiot? probably not
did he perhaps misunderstand you? thats the likely scenario. a lens that is sold for $850 in the US will not be sold for $400-500 elsewhere. but hey, if they make the mistake and sell you the 35mm for the 30mm price, then id say it is a good deal.

Here are my questions:

1) Why do you want to shoot wide open to infinite?
2) What is the depth of field of at 35mm lens at infinite? What is the dof of the same lens at a short distance (less than 10 feet)?
3) If infinite is in focus, do you expect everything else to be in focus?
4) What is the purpose of a wide-angle lens as compared to a tele-objective lens?

Also it is my understanding that at longer distances phase focus isn't quite as accurate as contrast focus, try again with Live View?

It could be, in all cases i will not buy 30mm, it will be clear if i see the box and open it to see the lens, once i confirmed it is the new one and get it at that 30mm price then i think i shouldn't wait any longer and buy it immediately, if you want send me $500-550 and i will buy for you and send it to you

Okay I'm starting to see what Cory and the rest mean by shooting past 10-15 ft for the environmental portraits. I completely forgot Dan's shots are 80-90% wide open and he's standing super far away to get the gorgeous backdrop that he always does! At least now I know what to test for and it's a nice bright and sunny Saturday.

I'm really enjoying this lens, very fun and consistent.
Quick shot i took at a bar.

so some tests? lol
