SFBAY Pro Remote Shutter Release Connection Cable Compatible with RM-S1AM Replacement Commander for Sony Alpha DSLR A900 / A850 / A800 / A700/ A560 / A550 / A500 / A450 / A400 / A350 / A300 / A200 / A99 / A77 / A65 / A57 / A55 / A37 / A33

I tried it with a37 and a65. Fits well, works fine, no problems, so far. Price was good, free shipment, and came fast.

As promised, worked perfectly w/ my Sony a65. It feels well made. As you may know this is a proprietary plug, so be sure 4ft is long enough for your purposes. (I didn't look to see if anybody made one any longer, or if there's an extension.) Really like that I can lock focus with it (half press, just like the shutter button).

I've only used this a few times but it works very well and seems reliable. It fit my Sony A37 perfectly. An inexpensive and practical solution for camera shake especially for landscape photography.
