You can see the field test images from both systems, taken at the same time, over on my pet and animal photography area by clicking on this link: Olympus OMD and Canon 5D MkIII Field Samples
Before visiting the link do bear in mind that this is not really one of those weird Olympus OMD vs Canon 5D MkIII essays, since the two cameras are very different. But following on from the many big discussions around the web about professional photographers switching to smaller mirrorless systems I thought I’d demonstrate the capabilities of the OMD in the field when shot alongside the awe-inspiring Canon 5D MkIII (a machine which is at times vital to my business). But is the 5D MkIII vital to me all of the time? No, of course not, the recent inventions in miniaturised camera systems has meant that many tired professionals now have the option to use small lightweight kit for many of their assignments – assignments which don’t necessarily require ultrafast tracking focus or ultra lowlight capability. I will say at this point that the Olympus OMD is no slouch when it comes to either, but there are still some situations where a professional grade DSLR will be “the best tool for the job”. And that is key to anybody running a photography business, what you purchase is not about what you fancy having, it’s about getting the job done properly and investing wisely in your equipment. When professionals make such investments we need to calculate the cost/return point (such as when the equipment will have paid for itself given the number of assignments it will see and the projected income generated). If you’re a hobbyist then those calculations are likely to be less important and you’re more or less free to simply buy whatever you like. But with new developments you may not need to spend quite as much as you did previously, because good compact systems can easily replace a good DSLR in many situations, providing you are able to team it with the right optics.
For me, as a professional portrait photographer, I am more than happy to use my mirrorless systems on many of my assignments (I currently own the Olympus OMD EM-5 and the Fuji XE1 with various lenses) and a couple of days ago I took one of my students into the field to demonstrate that high quality photographs (providing you understand the craft of photography) can be had from small lightweight kit. Why kill yourself lugging around several kilos of equipment when a tiny system will do just as well?
I stress I am not trying to kick off an exhaustive Olympus OMD vs Canon 5D MkIII debate, I’m merely highlighting the benefits I personally will reap from downscaling some of my equipment.
