    Hi I have an Olympus epl-1 and just picked up the Panasonic 100-300.
    Although I am very impressed with the sharpness of the photos I'm getting even wide open and at 300mm, I've noticed that the lens is much slower to find and lock focus than my 45-200mm Panasonic, 20mm, and even the epl1 kit lens. I was wondering if anyone else had noticed that the lens was slow to focus on the Olympus pen cameras.

    Here's a photo I took this afternoon with the lens at 300mm and at widest aperture. I'm liking what I'm seeing with the end result of the photos but I'm definitely not liking the slow focus. Any other PEN users have a similar slow focus problem or is this just my copy of the lens?<a href="http://www.flickr.com/photos/janie_miranda/5493027102/" title="Plum Blossoms by ~Jane, on Flickr"> 5493027102_4260d8d72c_b.

    that is the pretty common responses of the AF speed of the 100-300. It is said to be a little slow also on a panny body.

    I am very impress for a 300mm shot, all the panny body samples I seen at 300mm are a bit softer.

    shoturtle, oh thanks so much for the fast response. I was afraid I got a defective one but mine is definitely a sharp copy (as long as I keep the shutter speed up!) I found I had to do some manual focusing too because it was doing a lot of hunting. I'm going to give it another try tomorrow in some better light.
    Thanks again,
    jane

    It looks like a winner. Think if you want faster AF you will need to look at the mcs lens form oly. The 75-300.

    Thanks again for the suggestion of the 75-100 shoturtle. I think I'm going to keep this lens though. After playing with it this morning in better light the auto focus seems good enough and I'm very, very happy with the image quality. I have the 45-200 also and I rarely would use it longer than 150mm because the images became too soft, but I'm finding that I'm getting good sharp images through out the range with this lens. I'm impressed with it.

    Yeah, the panny lenses are very good on olympus, with the correction and the great jpeg engine. I love the 45-200 on the epl-1. I have a pretty sharp copy at 200mm.
