I finally received my Really Right Stuff (RRS) grip for my E-M1: http://www.reallyrightstuff.com/s.nl/it.A/id.2237/.f. There were only two aftermarket grips available for the E-M1 and I had no interest whatsoever in the Olympus grip, as it came across as an overly large addition to the E-M1 and would only have been useful had I still been doing sports (for the extra battery life). It’s undoubtedly a good grip, but I just wanted something that added a little more to the height of the body for better purchase, as my pinkie finger was somewhat lost for something to do when holding the E-M1. The alternative grip available for the E-M1 is the JB Camera Designs grip, http://www.jbcameradesigns.com/new-grip-base-olympus-om-d-and-e-m1, but after seeing a review of the grip, I was rather put off with the design. Some may see my views as minor quibbles, but aesthetics is an important aspect to me and there were several things I didn’t like about the JB grip. The first being the fact that it didn’t conform neatly to the camera base design and it had an odd cut-out on the right hand (looking from the front), which I couldn’t find any reason why it had been designed that way. The second thing was the brushed aluminium look, which I found very out of place when compared to the finish on the E-M1. The RRS grip, on the other hand, comes with a very nice finish that matches the camera well. I was a bit dubious of the RRS branding on the front, but it’s actually fairly subtle in reality vs the website photos. The grip also conforms to the shape of the base so much better, with the body actually sitting inside the grip, meaning that it’s far more secure (more on that later) and for someone who didn’t know, it looks like a factory part of the camera. An additional excellent feature is the Arca Swiss compatible base that goes the full length of the grip. For anyone who uses Arca Swiss compatible mounts, this is an excellent idea, in that you don’t need to attach a secondary mount that invariably becomes a hindrance when you don’t need the mount. For anyone into stereo photography, the mount makes for a perfect slider. The underside of the mount has also been well thought out. The screw that attaches the grip to the camera body is separate to a second screw hole that allows you to also affix the camera to a standard tripod screw head, which is centred on the lens axis. This is a nice touch that provides some flexibility to the grip (the JB grip just used the knurled knob to attach the grip to the camera and I’m not sure how well this would take an Arca Swiss mount). Battery access is easy, so nothing really to discuss here. The grip also comes with a slot that lets you attach a strap or the like for those who don’t like camera straps (this is something the JB gip didn’t have) and with the way the camera sits inside the RRS grip, if you do use a strap, all the weight is not taken on the mounting screw, but through the entire grip. This makes strap attachment so much stronger. There is also another slot and screw hole on the opposite end that allows you to attach a vertical plate. That’s the technical details out of the way, so how does it actually feel on the camera and in the hand? Very good to be honest and, as this is the first RRS item that I’ve ever bought and having read excellent reviews of their gear, it’s now clear why RRS gets such good reviews; the quality, fit, finish and ergonomics are really excellent. It’s not as tall as the JB grip, but I no longer have an errant pinkie finger, as it’s able to rest against the grip and I’m not sure that a taller grip would have been any better. While the E-M1 was a nice size, I found it just a little too small and now it feels just right. It’s too early to say if there are any niggling issues with the grip, but I certainly can’t find anything to nit-pick at the moment. So if you have been pondering an additional grip and have been tossing up between the two mentioned, I can confidently recommend the RRS grip.
