.. using crop-sensor cameras?
Now that full-frame digital sensors are comfortably established in the more high-end cameras on the market today, is it really feasible for a pro to hold on to DX format cameras for their pro work? Is it inevitable that we'll begin to see pro photographers arguing that all serious pro photographers are using full-frame bodies? Is that happening already?
If you're a pro photographer using FX format bodies, have you considered, or even started, using this fact as part of your pitch for, say, wedding shoots?
This makes no sense at all. Your camera is a tool, a recording device. Depending on our work pro photographers normally look for certain performance benchmarks, such as fast frame rates and weatherproofing if one shoots sports, and good low light capability for weddings. But the fact remains that the majority of DSLR cameras produced in recent years easily meet those criteria. Having the correct tools for the job is one thing, but it is totally irrelevant unless you have the skill and experience required to produce merchantable images. I'm fortunate to have top spec equipment at my disposal, but if I put it into the hands of one of my trainees then the results will be no different to the results they will produce with pretty much any camera. The unfortunate fact is that your camera will not light your subjects, nor will it pose them, or interact with them, frame your image or choose your locations, process your shots, etc etc. Sadly that all takes many years to grasp.
I shoot with two primary systems, one being my 5D MkIII bodies and L lenses, the other being my OMD and u4/3 lenses. I very rarely use the MkIII these days, that would only be if I were requiring fast tracking focus for the rare occasions when I am photographing a fast moving or erratic subject, or representing Canon. The OMD covers most of what I do, and I have some very demanding clients and I have very high personal standards.
The whole depth of field argument makes me laugh. Sensor format is but one of several factors which you can manipulate to control your depth of field, and more often than not the format which offers the most DOF will prove to be the most useful. For example, let's say I'm photographing in a dim location where I am not allowed to use any flash. You might instinctively think that I would reach the MkIII, but in most cases you would be wrong. After all, in a dim environment I will be increasing my ISO and opening the aperture, right? Correct, except on the MkIII my DOF might be very shallow indeed, particularly if I'm fairly close to my subjects, and unless I can manipulate the situation to ensure that each of my subjects is on exactly the same plane of focus, one or more of them will be slightly de-focused. The beauty of the OMD is that I can fit a fast prime lens and shoot wide open, gathering all that lovely light, but I will have almost 2 stops additional DOF than my full frame DSLR. This also means that I will be working at about two stops lower ISO on the OMD, totally negating the ISO advantage of the FX camera, but mercifully lightening the load on my poor old joints. And the IQ and dynamic range from the OMD is spectacular. There are also many other scenarios where the additional DOF offered by a slightly smaller sensor body will help you out.
My clients have no influence over the kit I use, that is my decision and mine alone. They choose me based on my work, my reputation, and to an extent my qualifications. I have no insecurities about being judged on the size of my camera.
So, in terms of your proposition, my answer is a very emphatic no. From what I am seeing more and more professional photographers are turning to more compact systems, because they are sick and tired of knackering themselves hauling around several kilos of 'the big stuff'. Unless you're doing the kind of advertising photography which demands massive resolutions then the full frame argument is growing increasingly weak.
