For example, a manager will have to dress smart and maybe use clothes with a famous brand, and he will have to get an expensive car to show his customers that he and his company are successful.
Dressing professionally is one thing. The tools you use are quite another. Of course for someone in a position where image is everything they may want their tools and their accessories to be as much a part of their image as their clothes... so I'm not disagreeing with you. However, photography is a creative profession, and creative professionals are generally granted a lot more leeway when it comes to image. If someone is hiring you for your talent, they of course want you to use the tools you are comfortable using. Or they should want you to.
For a professional, gear and appearence do matter. Of course you can always make a portfolio with the EP-1 and, if somebody complains that you don't seem to have professional gear, explain why you are using the EP-1 and show them your portfolio.
This is good advice, because they can ask any gear questions they have up front. Maybe it isn't right for a client to question your choice of gear, but it does happen. Personally I like to be up front about the gear I use and also how I like to work. There is a danger in this though... they might go with another photographer because they think that photographer has more professional looking gear. In an ideal world the clients would base their decision on the final product alone.
Because if you're a professional you must be able to shoot in the most difficult conditions, that's when fast lenses, fast SLR bodies, weather sealing and so on get involved. And while the EP-1 might be the perfect camera for the hobbyist, it might miss some features that are required for pro work, regardless of the artistic quality of your pictures.
This all depends on the types of professional photography you engage in, but yeah... for most pros that means quite a variety types of photography in a variety of conditions. So you do generally want robust high performance gear and redundancy.
And if I were a couple that pays a lot of money for their wedding pictures, I would be really upset if somebody would show me a bunch of grainy pictures saying that they make an artistic B/W...
But some people
do like that style. Some people even pay a premium to get that style. That's why many pros use software to simulate a certain type of film and processing... grain and all. Many of these programs and techniques can really improve shots with digital noise by giving the noise a more organic looking grain effect. Some of my favorite shots were super noisy images that now look like they were shot with high speed BW film thanks to Silver Efex Pro.
So, you see... I agree with you for the artistic part of your post, but if you're a professional and get paid I think that your equipment must be adequate.
The OP's situation was kind of unusual though. It wasn't a wedding, and the OP said he is getting out of the biz as well. It was a previous client and the gig was to take casual candids for a website. I could see using an EP1 or GF1 for this for a variety of reasons:
- Available light capability as well as flashgun support
- Small camera might allow the photographer to get more natural shots rather than everyone smiling and posing... he can blend in with the crowd a bit more easily.
- Even if the high ISO shots without flash are a bit noisy, they will be for Web display and not large prints.
But yeah... if I were hired to shoot such a gig I would show up with both a m4/3 camera and my usual gig setup. I would use the m4/3 for some shots, the DSLR for others, and see how things go. I'm getting a GF1 with a pancake prime in January, and I will certainly take it with me to the next gig I photograph. My Nikon DSLR cameras will still be my primary cameras, but I will probably take some shots with the GF1, especially:
- During the ceremony if pictures are allowed. The last wedding I photographed allowed photography during the ceremony, and when I warned the bride about how loud the camera would be at the quiet moments she said, "I don't care... I want those pictures!" I know m4/3 isn't silent, but it's at least quieter... which would make me feel a lot better the next time bride asks me to shoot during the ceremony.
- During the reception for some of the candids. Yes I would probably use my DSLR with a flash bracket and/or diffuser for the bulk of the shots, but I can think of some moments that would be easier to capture using a less conspicuous camera.
So these cameras may not be designed for the rigors of daily professional use under a variety of conditions, but that doesn't mean they are not useful tools for a professional photographer to have in their bag. Many pros already carry compact P&S cameras along with their DSLRs for similar reasons.
Would I show up with only a m4/3 kit? If I was confident in my skill with the particular camera, and I had a backup, then yes... but I would probably explain my gear choice to the client ahead of time. I do that anyway since even if you show up with a DSLR some people question your brand of choice.
