Default Sigma DC HSM 30mm - adapter

Hi,

I have a Sigma DC HSM 30mm with a 43 mount. I'm looking to upgrade the camera body and get a m43. Does anyone know how the Sigma will perform with a 43 to m43 adapter? Im a bit worried about slow AF.

Thanks in advance!

no help here about that, sorry, but I've heard that that is one fantastic lens!

it might perform okay on the E-M1 since the E-M1 has PDAF on sensor, but all the other camera bodies it will not perform very well.

Yeah, the E-M1 is probably the only body where the AF will be at a good AF speed, assuming it plays well with the four-thirds to micro adapter like the other four-thirds lenses.

The 50mm f2 Digital Zuiko, which was a sub-standard AF lens on most of the DSLR's before the E5, autofocuses great on the E-M1. If the E-M1 can focus the 50mm f2 fast, I'd be shocked if it could not with the Sigma 30mm f1.4.

Thanks for the comments. The E-M1 is a pretty expensive on body...I'll need to figure out if I should sell the Sigma and get something equivalent with the m43 fit. I do like the Sigma though, it's my de-facto lens for portraits which is 90% of my shots.

Yeah best buy on em1 is to find it refurbished on sale at the Olympus store.. $839 or so. Probably next sale will be black Friday.

Otherwise it will be a little while before we see the pdaf sensor trickle down to a lower end body.

On the other hand the excellent for portraits 45 f1.8 is very affordable and will work on any m43 body. The pana-leica 25mm f1.4 is around $550 (still) but there is also now the Olympus 25 f1.8 which is more affordable.

I would also point that the newest bodies like the em10 have focus peaking which allows focus to be manually dialed in very easily. For portraits this might be an easy way to nail focus with the sigma 30mm you have. This shot was taken with an old Konica hexanon 50mm f1.8 using focus peaking
