    Hi all,

    This is my first post to these forums. I've had an OM-D for about 6 weeks - loving it! My Canon 7D has been sold to fund my new addiction :)

    I picked up an Olympus 75mm F1.8 this morning - haven't had much chance to play with it yet but one I thing I did do was to try out some 58mm Canon Close-Up Lenses that I purchased years ago to use with a Canon Powershot Pro1.

    The Canon 250D doesn't seem to work - lots of halos. However the 500D seems like it might be OK... although contrast might be down... I'll have to do a lot more pixel peeping to see if I am happy with it but it certainly lets the 75/1.8 focus much closer...

    Some samples here - AdrianSmith Photography | Testing

    (manual focus so not spot on - was trying to keep lens at closest focus distance and then moving camera back and forth until text was in focus).

    Any suggestions on how to really test out this combination would be greatly appreciated.

    Adrian

    For some reason our automatic moderation software blocked your post, and my work is blocking your website links claiming that they are pornography :confused:. I can see via my phone connection that they are not, so no sure what the problem is. At any rate, welcome to the site and sorry for the bumpy start!

    Welcome Adrian,

    I'd suggest stopping down a little when using this lens with such short distances in order to have more DOF, that will also help with the focusing.

    Sometimes it's easier to move the object in focus depending how the camera is mounted, tripod or something.

    I'd be interested to see some regular photos from this lens as well. Did you get it for a specific purpose, portrait/headshots, or just a general fast telephoto?

    I try to use F 8.0, or higher, and focus to infinity. Gives just a bit more working distance and depth of field, which is thin at best. Close up adapters work better with some lenses than others. Use flash with diffuser and dialed down power, for faster shutter speed and better detail. Then Practice, practice, practice. It does get better.

    I've been using a +3 diopter on my native u4/3 lenses. Even with a high quality achromat like the Canons stopping down improves the image quality. A lens hood will help with the contrast loss. I always use one.

    As the magnification increases the focusing mechanism will have less range. What I've been doing is manually set the focus to the "middle", move in to get the composition then auto-focus for a final adjustment. I often move the focus point to the area I want based on the composition. It's a simple process to switch from manual focus to auto and to move the focus area on my G2. It may or may not work out on the EM5.

    This is with the G2 iso800, 1/20, Panasonic 45-200 @72mm f/7.1, Marumi +3 achromat. I forget what string of letters and numbers they use to name it.

    Not really into the macro range, but closer than the lens alone allows. I used the techniques described in my previous post. Hand held with OIS on.

    Thanks for tips.

    I bought this lens as a general purpose fast telephoto - I will use it at lot at "events" (like lectures, dinners, etc) but also for portraits/head-shots and even for some sports (kids netball where I get right up close to the court).

    I'll post some more images in the near future - was very happy with some I took yesterday at a family birthday party.

    Thanks everyone for the tips!

    I'll post some more photos after I've done some of that practicing :)
