I have been into macro photography for a while and I have something called a focus rail made by cowboy studio which is used for depth of field stacking. I noticed that it was made from two dovetail pieces bolted together and I had to test it out on the CG5 mount to see if it would fit.
Sorry for bad quality, I used my iphone and it was dark outside. As you can see the focus rail fits very well into the mount and I saved probably about $100 on a dslr dovetail setup for this mount. I got the cowboy studio unit for about $45, but you can get a single rail off of ebay for about $15 here http://www.linkdelight.com …op.flypage&product_id=958
