And I think I'm going to sell it. I bought my E-M5 kit for full price soon after it was released because I'm a gadget geek and wanted an interchangeable lens camera to photograph my first born. It took some time to discover the world of non-kit lenses and bokeh. That opened the door to buying fast m4/3 primes with great auto focus. Then came the DRTV videos. The allure of full frame bokeh. And the general impression from Kai Wong that a 5Diii is pretty portable and can easily be toted around with one hand. It fed my dissatisfaction with E-M5 since I always felt that the E-M5 wasn't as portable as it could be, especially with anything other than the 17mm f1.8 or 20mm f1.7. Definitely not so much with the hand grip, or the 12-40mm f2.8. So why not try out a FF DSLR and see how it goes? Well, I bought a used 5Diii instead of an imported D750, picked up a sweet Sigma 50mm f1.4 and went to town! No Like: 1. The 5Diii + Sigma 50 is a monster to hold. It's ENORMOUS. And it's not even the biggest 50mm out there! The Canon 50/1.4 and the Sigma ART are both even bigger and heavier! Often I find myself cradling the beast like a newborn baby just to get my keys out of my pocket! No like. 2. Razor thin DOF is over rated. In fact I find it really distracting now. I can't stand shooting with the Sigma wide open. It has noticeable glow wide open, and I generally have to shoot between f2.8 and f4 just to get my subjects in focus. No like. 3. Stopping down the aperture often means boosting ISO. No likey. Kinda. But in reality the 5D's noise is acceptable up to 10,000. Whereas I on the E-M5 I shoot 6400 only when I'm desperate. 4. The ISO thing wouldn't be so much of an issue if i didn't have to keep my shutter speeds above 1/125 or 1/160 to get a sharp image. Either I have shakey hands, bad mirror slap, or I've just become spoiled with 5-Axis IBIS. No likey. 5. AF. While AF is quick and C-AF is leaps and bounds better than the E-M5, because of the shallow DOF, I find myself obsessively refocusing before every shutter release. It may not really be necessary, and my confidence may improve with use, but right now it's psychologically burdensome. 6. Strobes. Stopping down the aperture for DOF means boosting your strobe power. no like. I've also been spoiled by the Olympus RC Flash control. Like: 1. The OVF. No delay. No prolonged blackout. Continuous shooting is great. The EVF blackout on the E-M5 is really annoying. I hate the idea of upgrading the body just to get a better EVF. 2. I was expecting skin tones to be captured and rendered much more beautifully on the FF sensor than the m4/3 sensor. And to a degree, it is. In the shadowy areas, the FF sensor produces much smoother light fall off in the shadows. But in the highlights, not so much. A lot of the "smoother" skin I envied in other peoples' work was really just a result of over zealous noise reduction, which you can impose on a m4/3 RAW too. 3. Adapted lenses are much more compact on the 5D than the EM5 because of the flange distance. OM mount lenses on the 5D are super compact. Love this. OM mount lenses on the EM5 look like ungainly protrusions. Here are some comparisons. See if you can tell which is which. In the meantime, I'm open to hearing reasons why I should keep the 5D.
