^- i have that concern sometimes too...

The thing for me is i cant actually reproduce the focus issues over and over again, Sometimes my Sigmalux just decides it want to front focus a ton... Most of the time its fine... If i bolted it up and did a "focus test" it would work perfectly fine...

However once in a while it just decides it doesnt want to work right, Seems to be anytime theres a lighter colored subject, or theres good lighting it will botch the focus... Granted it doesnt happen often, but when it does it causes me no end of aggrivation... But then again I've noticed the same problem on some of my other lenses, Just not as bad as the Sigmalux

That also makes me very hesitant to sell it (As I've pondered going to Nikon once or twice) Because i dont want to deal with it if someone complains i sold them a bad lens

By your description it sounds like it's more a problem with your shooting technique than anything else - a large aperture prime is fairly demanding in terms of technique, when shooting wide open, especially when you use longer focal lengths and the DoF becomes really thin...

Use the back AF/*/whatever button for AF and not the shutter button, use AF servo mode and use a single point AF thing, because with DoF that thin, it really doesn't help when the camera tries to focus on multiple different points (not sure if specifically you do any of that or not, just saying for the benefit of anyone reading), and focus on a high contrast area, preferrably one that isn't a pattern of sorts. Having a precision matte screen helps as well, because with one, you can fine-tune your focus if need be (never had to do this myself - bought mine so I could use manual focus lenses, but it's always a possibility).

I've never missed a shot with that method, so I recommend you give it a go if you haven't already.

No method is flawless and no lens is perfect, but one can learn to work around or live with the quirks of various pieces of equipment.


A good photographer can take extraordinary photos anywhere, with any camera and any lens while a mediocre one will take mediocre ones everywhere, with every camera and every lens.
Never limit yourself with what others think you should do. Shoot what you find interesting, exactly the way you want to.

^ When you say "high contrast area", are you referring to a bright spot amongst a bunch of dark? Or vice versca? What do people mean when they say "high contrast area"?

Do I have to find a spot that has both dark and light?

7D, No precision matte focusing screen available, which is something that drives me bloody nuts because you only see f/4 in the viewfinder (IE, You cant tell the thing isnt in focus until you check the rear screen)

As for technique, I use AF ON for AF, single point (or single spot AF) only, I know what I'm doing, I'm not new to wide aperture lenses (My kit includes the 28mm f/1.8 and 35mm f/2, as well as a 100mm f/2.8L IS Macro) I've been down the path of trying to explain this before, and this is why I gave up on it...

Not meaning to sound mean or anything, Just trying to state an observation, Observation being MY Sigmalux on MY 7D has iffy focus performance in what people here would call "ideal" conditions, Dealing with well lit contrasted subjects that are not moving...

I will also note that as i stated before, its kind of a random problem, Sometimes its perfectly fine, I have yet to find any correlation in focus distance or anything, The only correlation i can come up with is when it happens, the situation is on where you'd expect a best case scenario with a well lit subject, good contrast, a high shutter speed, and a low ISO, On top of it as i stated before, I've shot bursts and its all consistent (IE, I'm not moving back and forth, Subjects not moving back and forth) Its just basically like the lens is going "Yeah, Dont feel like it mate" I guess i could say it doesnt like pets, Because the occasions i can specifically think of off the top of my head involved a puppy and 2 cats... and Skye obviously all in a well lit situation...

Now I will ALSO state its random and while it can ruin one shot, We're talking a problem that affects maybe 1% of the shots I've taken with this lens, For instance the day i went for a walk with nothing but my Sigmalux I didnt have a single issue and that was a situation with pretty good light and such... I've taken tons of portraits of Skye as well in good light and poor light with no trouble... It only bugs me because it crops up randomly and i only realize when i chimp...

Ok so im probubly just nitpicking over something so minor, Its just highly annoying when its like "HEY IM NOT GOING TO FOCUS CORRECTLY U MAD BRO?" for literally -no- reason

You basically want something with some kind of detail on it...

IE a blank piece of paper is bad, a piece of paper with an X drawn on it, good
