Correct - if there *IS* a performance hit, I haven't seen it or read about it.

So have most OM-D users upgraded from the 20f1.7 to the 25f1.4?

The 20f1.7 seemed to be first good prime, so I assume their were many early MFT users.
Now I see so many photos on this thread using the 25f1.4.
Is it that much better? Is it the DOF, AF speed, bokeh?

Everything is a little bit better with the 25/1.4, so overall it's preferable. But it's much larger, especially with the hood on, and of course narrower.
The worst thing with the 20 is the terribly slow and inaccurate AF. Sometimes it just hunts for five seconds without finding anyting, even in good light.


Thanks Makten,
That's the kind of info I'm looking for. I typically like the 35/40 mm focal length (35mm equivalent) better for "general" use, but I might try the 25. I just a beginner with the OM-D and 20/1.7, so I'm just starting to notice the AF issues with the 20.
I've also noticed that it doesn't like shooting toward the sun.

I could see owning both, really - the 20 is a nice FOV and pocketable, the 25 is faster in aperture and AF, and they seem to render a bit differently.

I'm always surprised to hear people complain about the 20's AF - I've never had an issue with it. I often take shots like this hiking at large apertures and a large majority are in focus......

many outstanding images yet again from everyone. Out trying different things toaday. often it can be a good idea to post even if you are not convinced. Next time you look in on them there can sometimes be a bit more clarity as to what you have posted. Good or not so good.

Love the first one especially.

I keep thinking about picking up the 7.5 Rok- would love to see more.

A few from a hike yesterday....

45 1.8...

I highly recommend it. Great lens, small, easy to correct if you really want to (I use Fisheye Hemi's "cropped" profile in Photoshop, which doesn't make it architecturally good but can defish it a lot.. but you can get away with the Sigma 10mm FE profile in LR4 if you want to correct it there). I typically don't correct it.

My thought was at $300-ish having a small, UWA is a no-brainer, even if it's not AF. If I really don't want the FE look it's pretty easy to get rid of (unless again you're shooting for perfectly straight lines).

(some of these might be reposts!) All with the Rok 7.5mm

^ I had to clone my shadow out of this shot - massive FOV with the lens.

I'll be moving to Albuquerque NM this coming Feb, so hopefully I'll be able to put it to much more use in the landscape department.

Interesting lens the Roker .I can imagine having a lot of fun with it.

Thanks, I think you sold me on it. I've got the Pany 14 2.5 and for wider shots I often shoot pano's, but having a FE would be fun for travel.

RKTodd I too have the rattlesnake noise with the PL 25, it's an annoyance at the most. I have never seen it affect a photo or the performance of the lens.
If it acts up while I am not shooting or in a hurry I turn the camera off and on and it seems to settle down for a while.

The lens is amazing in every other way.

Second shot is great JUJU, love the all black water!

Juju, what is your post processing technique?

Beautiful set Julian!

Thanks for the feedback on the noise. I plan to place an order for that lens this week. I have the 45 1.8 coming on Wednesday--can't wait to play!

Love the dog photos with the 45!

Turn off the Fulltime-AF option to avoid rattlesnake on PL 25.

rji,

what wonderful pictures of a couple of beautiful buddies

That may help but it doesn't completely alleviate it. I have had that option disabled since day one of my OMD but I still occasionally get rattlesnake.
