I'm embarrassed to ask, but I'm borrowing this lens and don't know what this ring is for. Help me /p/.
...it's the manual focus ringnever used a lens with internal focusing eh?
sigma 10-20 for life!
no thanks
OP here, so wtf should I set it to when I'm using AF?
>>245737just don't touch it. The ring it self won't rotate on it's own when you use auto, but you should notice the focusing range change in the little on the lens (which you can thoroughly ignore).
well, its a usm lens. you can just grab it any time to override the auto focus.
Enjoy your awesome lens, n00b =D
I didnt know they made lenses all teh way down to 10mm!!! xD if u dont enjoy ur lens imma get ur ip address find u and steal it :P (not rlly :x )
>>245786your newfag is showing
>>245786>>245773Samefag?
>>245786EF-S for crop body. I have it, it is pretty wide, but I wish I had wider.
Whats with the sudden influx of emotes on 4chan :S>OP - its a focus ring
>>245751Only works with Ring-type USM.>>245786Focal lenght is 10mm, yes, but it doesn't make a image circle larger than APS-C sensor. Thus the maximum FOV it can produce is 16mm.
>>24591515mm no? Assuming you fitted it onto a nikony body, APS-C goes wider than 1.6x.
>>245924>>245723>Canon EF-S 10-20mm>Canon>1.6 crop
>>245926well done, you can read and write! Now try to understand what you are reading!
wow, butterfly sure is stupid
Omg, Butterfly, I'll help you out. This a Canon series lens, so that would mean that it adheres to the Canon crop factor which is 1.6x. Where your getting this is a Nikon lens is beyond us.
>>245949>>245952>Assuming you fitted it onto a nikony bodyAdaptors motherfuckers have you heard of them.
>>245961oh wow, you really really are fucking stupidyou realize the EF mount is about 30% larger than any other mounthave fun fitting it inside the tiny little F mountand also have fun with the short back focus on an EF-S lensconsider yourself learned and get the fuck out of this thread
>>245961Do you always automatically assume that people who buy a Canon lens buys it so they can fit it on their Nikon body? lol
YOU CAN'T FIT CANON EF LENSES ON NIKON
Who says you can't mount CANON EF's on a nikon..
Martin makes Butterfly look like a genius
You'll have the added benefit of it being weather sealed too.
>>245965Well it would be pretty obvious to assume so if you're replying to a post that is talking about it, right?>>245885It's called trolling :DD
>>245924Assuming that canon didn't make it for Nikon but for Canon cameras.Wow, you're so stupid.
wow you lot sure dont like getting upset.If anyone wants to buy me a 10-22 i'll bolt it onto my A100.
>>246052Can you bolt me on that sleek body of yours also?
>>246052Oh my god. Sony fag.
>>246092sure but you look a little small for my mount :3
>>246052
