I have tried to ger the answer via searching the forunm and was only confused. Do the 4/3 lenses like 40-150, 14-54 work with AF on EPL-2?The above lenses AF works on the latest E-DSLRs in LV mode. Is that means they will work on EPL-2 with MMF-2 or MMF-1? Thank you for the help. Leo

They work with the adapter. Slower than the m4/3 lenses, but work.

Some answers in here might help:http://forums.dpreview.com/forums/readflat.asp?forum=1022&message=38433477

Is there any difference in AF speeds between M4/3 cameras with 4/3 lenses? Perhaps more appropriately, do Panasonic and Olympus show any improvement in this department with each new camera?I've tried 4/3 lenses on the E-PL1 and I wasn't impressed. IQ is the same though.

The G3 apparently has much closer to DSLR AF speed with Panasonic's lenses, not sure if some of this translates to CDAF enabled 4/3's lenses as well. We'll likely have to wait for user reports since DPR, etc. probably won't note this in their reviews. -- Sailin' Steve

The answers were very helpful and more comolete. There was a very interesting suggestion related to E-620 as a path. Thank you again Leo

All replies are related to Panasonics. Are native Olympus m4/3 faster? Leo

Olympus lenses will probably focus a little faster (and more reliably) on an Olympus m43 body. That's my experience with with the 9-18. My E-Pl1 even focuses reliably (with a bit too much hunting for me) with my PanaLeica 14-50. Panasonic's CDAF is faster, with m43 lenses, but I suspect overall that Olympus's CDAF is overall more reliable when it comes to backwards compatibility. Hope that helps.

Leo,The 4/3 CDAF enabled lenses like the 9-18,14-42MKII, 40150MKII, 14-54MKII and 70-300mm all work nicely on the EPL1 with the MMF-2 adapter.I have all these lenses and use them with the E620 and EPL1.The AF speed of these lenses on the EPL1 is practically the same as on the E620 in Live View. Can't say I see much difference. Fast enough for what I mostly do, ie macro and nature pictures.RegardsCarlLeowrote:I have tried to ger the answer via searching the forunm and was only confused.

I think that the 40-150, 9-18 and 25/2.8 focus much faster on the PL1after the firmware upgrade.DPR and Imaging Resource made some measurements at that time with native m4/3 lenses and Panasonic was faster. It would be interesting to see what zuikos do on the G3, which has achieved 0.1 sec with kit lens i.e. dSLR speed.Another aspect is that it is much easier to MF with a Pen, due to automagnification. So I find myself using the 9-18 both in AF and MF, when I want to choose the exact focus point. One Fn button I use for AFL and then I adjust manually.Am. -- Photostream:http://www.flickr.com/photos/amalric

Carl, Thank you. You have very amazing lens collection! Congratulation!I have an unrelated question if it applies to your photography and based on your experience: what is the largest print size, which would look sharp to you can be printed from E-620 images with14-42 and with 14-54 mkII? Is EPL1 allows the same size prints? Thank you Leo

Leo,To be honest, I don't know. The largest size I ever had printed from the E620 was only 30cm in the longest axis. For all I know, the IQ of the EPL1/2 equals or betters the E620 , so I suppose the print quality from EPL1/2 files to be excellent too.Cheers,CarlLeowrote:Carl, Thank you.

Hi, I have made 50x70cm from the E300 8mp and 80x120cm from the 10mp E3 with very good results. Both using the 14-54 mk1. I think a perfect sharp 12mp will do 120x160cm without problems. Do you want bigger?

Using an EP1, I tried out my 4/3 lens collection.7-14. AF hunts, occasionally fails to get lock. The Pen has one thing my E3 doesn't have, though: a level indicator, very nice as the 7-14 really shows any lapses in camera level. Heck, just set it at hyperfocal, with this lens everything is in focus.PL25. Very good on the Pen. AF is reasonably zippy, about the same as on the E3, delivers the usual magical bokeh. And the PL25 isn't so large or heavy that it unbalances the little body. Surprised me how well this combination works together.14-54 I. Hunts a lot, eventually does get lock. We're talking 1-2 seconds to get lock, maybe 3 seconds if it's not in a good mood. The 14-54II is CDAF optimized and supposedly AF's quickly on a Pen, if you can find one.50M. It's an irritable fellow on the E3 if it misses lock, more so on the Pen. I almost always use this lens in MF mode anyway.50-200. Sames story as the 14-54 - hunts a lot. Can be 2-3 seconds to get lock, can fail to get lock some times.I tried out a 2nd generation ZD 40-150 when I was buying a MZD 14-150 (terrific little lens by the way, about the size of the 40-150). Focus speed was about the same.CDAF focus accuracy is extremely good. When it locks, it's spot on, regardless of which lens you're using.So why use ZD on Pen? The slower MZD glass, while tiny, doesn't have the 'dont worry about shooting wide open' nature of HG ZD. Shoot wide open in dim light, the slower glass goes soft. This is especially true when comparing the MZD 14-150 to the ZD 50-200.Also, the SG ZD glass, while no faster than MZD, is a lot cheaper than the MZD equivalent. Compare the ZD 70-300 ($200-250 used) to the MZD 70-300 ($600).I have tried out a GH1 as well. No difference that I could see in focus speed, it handled HG ZD about as well as the Pen, but no better.

Carl,The closer I am to replace my E-620 with G3/GH-2 or Olympus m4/3 the harder time i have to make such decision.I usually print 14" or 35 cm (longer side) from my E-620, however sometimes 16" (or 40 cm) without manipulating the image size. Also E-620 is not a large camera. My only problem with E-620 is its sensor. After using Canons for clients assignments I know how easy it is to photograph without worry about overexposure or extra noise. Any such Canon is larger, heavier and much more expensive. At the same time there is nothing wrong with my 14"-16" from E-620 images. It takes more to get there and some images would be lost but most of them are acceptable. Oly m4/3 may be a good addition of a light and very portable camera to E-620. Thank you for the help. Leocarlvdswrote: Leo,To be honest, I don't know.

I used the 7-14 on my ep1 for a vacation while my 14-35 stayed on my E30. The ep1 did great the whole time.The fastest lens I've used on the ep1 is the panasonic 25mm f1.7. It's almost like PD focusing.4/3 lenses that are not pdaf optimized like my 14-54 Mk1 still work and focus perfectly, but slowly.I'm sure the new pens do at least as well.Olympus and various reviews imply you can't use the non-cdaf optimized lenses, but that's not been my experience. -- John Mason - Lafayette, INhttp://www.fototime.com/inv/407B931C53A9D9D

To make it simpler I have purchased E-620 and happy. Leo

yes you can.. in fact that olympus launching its first m4/3 camera along with the adapter MMF 2 (4/3 lens to m4/3 camera) because during that time there only limited option of lens available for m4/3 system.. but the continuous AF for movie can not work with 4/3 lens.thanks arief
