Pansonic Lumix G7 -Adapter Ring Question (To Use My Canon EF-S Lenses)

Hi Guys,

I just ordered a Lumix G7 with 14-42mm kit lens. Im awaiting delivery. But meanwhile i would like to know if i can use my canon EFS lenses with this camera using...

Speedbooster (electronic) ?

Cost not small.

Viltrox adapter (electronic but little cheaper) ?

Might need to check on compatibility issue.

Manual ring ?

Basically you can't control f/stop.

Manual ring with only aperture blades ?

(so called the smart adapter?) no precise f/stop control.

These are the 4 options i keep seeing on youtube etc.

I mainly have a Sigma 10-20mm canon EFS mount and was wondering if i can use that on the G7. I just want to get a little more wider than the 14mm on the kit lens.

Can any of you help and advise ?

Are your referring to the Sigma 10-20 f/4-5.6 lens?

If so, I might rather prefer to spend some US$100 (a brand new de-kit lens) for a 12-32 f/3.5-5.6 pancake lens for the excellent AF speed, ultra light weight (67~70g depending on your version), compactness (24mm in length) and quite good IQ.

It has IQ very compatible to 14-42 (assume you have the Mk-II version), wider start of 12 instead of 14 (the 32mm vs 42mm is of no material meaning IMHO, but quite significant on the 2mm different on the wide end), and much more compact. The only draw back, no focus ring for MF. BTE the accurate AF of Pany camera making MF fine tuning be rarely needed.

Trade in the 14-42 (if possible, should in the same money as 12-32) and replace it with a 12-32 can hardly go wrong (at least to me).

I always do not think it is worth to spend the extra money (more than US$100) for a focal reducer. As the particular Sigma lens concerned does not have an aperture control ring, you at least have to spend some more money (than a cheap dummy adapter) for a smart adapter, plus the extra weight of the adapter itself... It would only be an advisable option if you have some very expensive L lenses.

My 2 cents.
