If you've followed my photo365 you will know I'm a fan of shallow focus, and bolting things on the front of a camera that weren't designed to be bolted on. My latest purchase is an 85mm f/1.8 Canon FD lens. You can buy lenses of this type on eBay for far less than the modern versions. And this one is much lighter too. I'll eventually get a Nikon or Pentax version (as I don't like the FD lens mount) but this was such a bargain I couldn't let it go.
It's attached to the front of an Olympus Pen E-P2 with a cheap Chinese adaptor. I added a 15mm extension tube to allow the closer focus. The shot is taken with the lens wide open.
I was photographing the neck then I saw the out of focus highlight and adjusted position so it sat in the dip of the guitar's body. It reminds me of a sunset. I focused on the thicker E string. I'm going to have fun using this lens. I just wish the EP2 would have the magnified view when focusing manual lenses as it's quite a challenge to focus using the screen at 100%.
