First of all, this is not a post about camera sync or using this adapter. All of that info and more can be found at strobist.com or here. No, I just wanted to share my impression of the PIXEL version of a hot shoe/PC adapter.
But what does is it do? Ah yes, this adapter adds a sync port to your camera to allow it to sync with an off camera flash. It does this while preserving the ttl function of your camera's hot shoe. Before anyone gets the wrong idea, this device does not allow ttl control of your remote flashes, only the one mounted on the hot shoe. Further explanation of this can be found on the Strobist site. This unit is only compatible with Nikon cameras, but PIXEL does make units for other popular makes. Since I am a Nikon user I purchased the Nikon specific adapter.
Nikon makes a similar unit, but it does not have the ttl pass through function. The plus site of this is that the Nikon unit will work with any make of camera except Sony. The downside of the Nikon unit is that it costs about $20. David Hobby, the man behind strobist.com recommends using the Nikon unit over the less expensive knockoffs do to durability, and until I purchased this adapter I would have agreed with him. Since I have purchased the PIXEL adapter I have changed my mind. Why you ask? Well, the big reason is that the PIXEL adapter only costs $10! That's a savings of 50%! In addition to the price, the PIXEL adapter has several advantages over the Nikon one. First, the PIXEL adapter allows you to use a flash on camera while still offering a PC port to trigger an OC flash setup. Second, The pass through functionality means that you can use the device to add a PC jack to a flash as well! Lastly, the Pixel adapter features metal hot shoe mounts both top and bottom and features an overall sturdier construction than the Nikon unit. Couple all of these advantages with the fact that this unit is essentially BOGO when compared to the Nikon unit and it is a clear winner. You owe it to yourself to have at least two of these in you bag at all times. Even if you use PW's or other radio triggers these could be lifesavers in a pinch, $20 for two is a small price to pay to eliminate a point of failure from your system. The first time a radio trigger fails, you will know what I mean.
