Sigma 30mm f1.4

hey guys,

anyone using the sigma 30mm f1.4 for video? i checked one in the store and the manual focus ring felt a bit "cludgy". wondering what your experience has been...

i know sigma has some issues with af alignment on canon bodies but this would be used for video so manul focus only.

thanks!

hi andy,

not looking for a specific comparison between the sigma 30 and the canon 28 (that's been played to death everywhere). my post was asking about how well the manual focus worked for people shooting vids.

specificially, the manual focus feels a bit rough - are people that are using it for video having trouble pulling focus or is it something that's working well for everyone?

k

Karl,

The Sigma 30 1.4 is on my camera all the time. I actually like the stiffness of the focus ring, It's very precise and intuitive. The 30 was on my camera almost exclusively during a 4 day film shoot for a commercial I shot.

Great low light lens. The only thing the lens misses is VR/IS. Tough to shoot handheld wide open. Great look though.

yeah you are right, it is a little stiff, I would rather a much smoother focus ring like some other lens but I can still focus pull with it, you need a stable rig so that when you pull focus it won't move the camera, despite that short coming, it is still my go to lens for low light work.

Affordable and reasonably sharp wide open. Focus gets a bit iffy at F1.4 so the stiffer focus ring (mine has it too) works out - I don't especially like the really loose ones like on some Tamrons. I usually stop down to 1.8 so the depth doesn't get too obnoxious. Hard to beat as a 50mm equivalent. No alignment issues, and focuses reliably but not as fast as an L series.

Great thread/inputs, as I myself am about to purchase this lens.
Could someone very quickly look over look over these two links and tell me if there is any difference, besides the price? I usually purchase from BH but with a lower price and a hood thrown in, I might go with Adorama.

They both have a hood but go with Adorama for sure, they are just as reputable as B&H, $39.00 can to for your protective filter, I bought tons of stuff from both company.

Hey Karl, this is a quote from 'the-digital-picture.com" in review of the lens...

"The manual focusing ring is smooth but somewhat stiff. The stiffness is not all bad as your hand will likely be holding the lens by/near this ring - If it turned too easily, you might produce OOF (out of focus) shots. AI Servo performance including accuracy is good. "

Just wanted to say I've been shooting a wedding this evening with the 30mm on the camera 90% of the time and still is. No way I could have done it tonight without it.
