User Manual for a Sigma 105 Macro

[smallboy3uk]

Hi, i have just brought one of these from ebay and didnt get a manual for it, does anyone have an electronic version, could scan the english part or let me have a link where i could download it from?

cheers in advance.

Si.

I've never even looked at my manual for that lens. There's not much to know, really.

Anything specific you'd like to know? I want to keep it in case I sell it and don't have a scanner.

Hmmm. I *do* have a digital camera though. Imagine that.

If you can't find one electronically send me a PM in a day or two. I'm pretty busy right now.

Hi
As Scotte's said there isn't much of a manual as such.You have the limit switch ie limits the focal distance the lens will focus at .Handy if your using it as a macro lens as if you miss the focus point it Will travel the whole focus range then back again ,a bit slow. And vis versa on longer focus range. Then you have auto or manual focus switch and a pull push ring for manual and auto focus.
I hope this helps..
ps i can also scan and send you a copy if need be..

Hi guys, thanks for the prompt replies.

Tommy6206, if you could that would be great, i will pm you my email address.

Also, don't forget to use the AF/MF switch if you are going to focus manually. If you use mostly Canon lenses it is easy to forget that some lenses do not have full time manual focus override.

Also, I believe that on the Sigma 105 the focusing ring has to be slid back towards the camera for manual focus. In the forward position it free-wheels and does not turn during auto focus.

I have no idea why they need both an AF/MF switch and a collar that is slid back and forth to switch between auto and manual focus positions. It seems a little redundant.

Optically it is an exceptional lens.

Yes,that two step idea for changing focus is utterly bizzare!!!!!!!!!!!!!!!!! :twisted: :twisted: :twisted:
I simply cannot believe they can design something so stupid.Surely they can cough up a couple of $ to licence the patent from tamron? Or make it some other way....
...ANY other way :shock:


But i must dissagree about it being optically exceptional.Sure it will flog any cheap or midrange zoom but against prime lenses it's very average-even the humble 50/1.8 lens equals/beats it.
If you want to see a seriously optically great lens,try the canon 100 macro (either version) :D

Check out this review-it's pretty close to the results i see when using the lens

Um, the push-pull thing on the 105 allows MF or free spinning. It doesn't engage or disengage AF.

Why?

When are you ever going to need manual focus with a free spinning focus ring or auto focus with the focus ring turning?

I'm not a lens engineer, but it seems to my simple mind that it would not have been too difficult to make sliding the focus ring back or forth also operate the AF/MF switch. (or the AF/MF switch engage and disengage the free spinning)
