I use this lens w/ the GF3 for video recording, &amp; its focus is noticeably slower than the 14-42mm kit lens. Is that expected or do I miss a setting?

This is normal. This 20 1.7 lens doesn't focus as fast as some other Micro 4/3 lenses. Take it easy and try manual focus for steady object or use other faster focusing lens.

I had a 20mm MkI on a GX1 side by side. I also have the EM10 with 17mm. I can't comment on the image quality. I sold my old Panny stuff and jumped on Oly camp without doing much. The 20mm is actually slower to focus compare to the 17mm on both cameras.

I haven't gotten mine yet, but I ordered it. I think I read that the silver ring on the front of the lense is how you adjust the focus...give it a try! If it doesn't work, contact the seller or something.

So this is a major concession in comparison with much less expensive cameras' focusing distances of one to two inches. Anyone with ideas as to why this is so. I used a Nikkormat with a Nikon macro lens for many years and have considered a Nikon digital body to allow continued use of the lens. Anyone with any thoughts on marrying such different technologies?

Sorry, I haven't had this problem. I think I remember it's best to focus from a normal angle to assure good focus zooming in. I presume you are also careful to center the image on the subject you want sharp. Ther might also be a setting to tell the camera how to handle close up shots. There may be levels orb types if selectivity possible. Depth of field is more critical in telephoto so it doesn't take much to throw it off. Sorry I don't have the camera or manual handy.

The chip is worth it for the metadata. I've found that it's actually hard to miss focus with this lens. I use the focus scale on the barrel and hardly ever look through the viewfinder to focus. Look up hyperfocal distance for 14mm and use those values. I usually just use the 3 foot mark on the lens barrel unless I'm trying to get something really close to the lens in focus. And by close I mean a foot.

I second guessed myself as well in the beginning. The lens has a pretty long manual throw. i.e. it takes some big turns to get things into focus manually. Keep trying and it should eventually get things into focus.

I found it to be very slow focusing at distances of less than 10 feet, since the depth of field is so wide and the camera (Canon T3i) gets confused. Manual focus works better in those situations, and is quickly changed with the forward/reverse clutch of the focusing ring itself. Tamron lenses have a very tiny focus mode switch to hunt for.

the autofocus is extremely loud and quite slow in video mode, and yes you will hear the sound of it in the video quite clearly. Also the lens will hunt for focus for several seconds. The only way I've ever been able to use this lens for video is to set it to manual focus. It takes some practice but you can get good at focusing it manually after awhile.

It does fine, but I haven't been to impressed with the autofocus in video with it. Manual focus is too slow for video. I would suggest going with a higher end lens for video.

Twist the lens. It may be that it is indeed too low to get a good focus. If you twist the lens on mine, it comes into focus.

I've been using Kenko close-up filters/lenses on my 14-45, 45-200. 28mm & 50mm K-mount slr lenses and they work pretty well. They really shorten the 36" focus distance of the 45-200.Even after 4 months, I'm not sure what the lady was really asking. I think she was under the impression that a G1 micro 4/3 had a macro/close-up mode just like a P&S;, and they don't.

None at all on my M- it is a bit slow in the focus- but when I combined it with a short loupe to act as a viewfinder it became handy. Mine works perfectly except for the focussing time. VRR

Low light with the kit lens is pretty bad. At f3.5 even with image stabilization you have to crank the ISO up. I'm talking on the beach by torchlight low light mind you. I mostly use the Sigma 19mm and 30mm f2.8 and the extra stop makes it a lot better. I'm sure with the Panasonic 25mm f1.4 this camera shines in low light. I recently took my G5 with 19mm to a gaming convention and the pics turned out really well.

iam using this lens with a GX 1 camera. i just did a test and shot a video and focused manually after setting it to manual focus with a button on the camera.it worked.

I love this lens and find it focuses quickly and is super sharp in good light, but I tried it out last week after dark at my son's marching band competition (HS football stadium lighting) and even wide open I found the focus speed slowed way down and I had far fewer "keepers" than I normally get in good light with the Sigma. My Olympus 12-40 2.8 PRO and my Oly 1.8 primes focus much faster in low light than the Sigma. I shoot with an OM-D with built in IBIS, and I used a monopod.

Mine works perfectly and I have no issues with sharpness. It's a very good walk-around lens when I don't want to carry a lot of gear.
