Focusing speed of Panasonic 20mm f1.7 MK II

The size is appealing to me, but I'm reading mixed reviews regarding speed of focus.
Nothing better than objective evidence, such as speed of focus compared to the Olympus 17mm f1.8 or compared to the Panasonic 15mm f1.7.

Anyone who is in a position to make such a comparison and provide feedback, their time and effort would be much appreciated.

Thank you.

Re: Focusing speed of Panasonic 20mm f1.7 MK II

I've used both versions of the Panasonic 20mm lens on an E-M10 - both variants offer lovely rendering and perform okay in decent light...I found it tends to hunt a lot with less light. Speed of focus, in my opinion, was the slowest of any lens I've used on the M43 system. I've read that speed of AF may improve if used on a Panasonic body but was a deal breaker for me.

I've owned the 15mm f/1.7 and it is a beautiful lens, IMO it is in a different league to the 20mm...really nice rendering, good low-light performance, close focusing capability, snappy focusing and well made.

I currently own the Olympus 17mm f/1.8 and can't fault it at all.

Re: Focusing speed of Panasonic 20mm f1.7 MK II

I have the H-H020, with the grey stripe, is this a Mk1 or 2?

I use it a fair bit on the E-M1 and have to be honest and say I've never noticed the speed! I have noticed the hunting in low light though.

Always pleased with the results.

Being fair though the go-to lens is the 12-40PRO, so I only use the 20 when I want to be a bit more discrete!

EDIT:

Just shoved it on the camera and done a very un-scientific test while sat in front of the computer "working"

The 12-40 is probably 5-10 times faster - and significantly quieter (which I hadn't realised!) The delay on the 20 is less than half a second normally, but in low light and big changes it can take a little longer.

Re: Focusing speed of Panasonic 20mm f1.7 MK II

The newer Panasonic F1.7 25mm is a great lens - I tend to alternate between the 17mm F2.8 Olympus and this on my E-M10
It's larger but a lot cheaper, Currys have it at 149 new.

Re: Focusing speed of Panasonic 20mm f1.7 MK II

Thanks to sdb123, Walti and AMc for taking the trouble to reply and to Walti for taking the time to perform a comparative test.

Since speed of focus is critical for my needs, I think I'll side-swerve the 20 based on what I've read.

Thanks once again.
