This Noname infrared remote control does what it should, namely Focus and Shoot. Who seriously compose a photo, has the other parameter set already is in advance and no longer needs. I use them on a E-520, the W / T / + / -. Keys are there no function The release button of the FB has no 2 pressure points (like the shutter button on the camera), but only one. When pressing the AF function is first activated, then triggered. You have set the camera to MF, is only the trigger, with a small but noticeable delay, I appreciate them on just under half a second. Whether this delay also occurs in the original Oly-FB, I do not know, because I have no comparison. I use the FB mainly to trigger in experiments, sometimes portraits, when the cam is on the tripod. Shutter lag does not bother me here, because I already have to correct depending on the movement character of the object.
As regards the size: even the smallest camera or pocket takes the 6mm thick FB easy place. Nevertheless, she is strongly built, the keys have a good pressure point. Conclusion: for the price a great relief that you should treat yourself to, because you have to stand in Armweite the camera does not always, worth all 5 points.
