it's all very nice and cuddly and friendly to say that equipment doesn't matter.
but it's also crap.
Anyone can take a nice photo of their kitten or a sunset with a kit lens. In the right hands, iphones take some BEAUTIFUL portraits.
You can't professionally and reliably take photos or make the kinds of images that many types of client require without tens or even hundreds of thousands of pounds worth of equipment (not an exaggeration). The latitude, the noise, the flare handling, the autofocus just isn't there on cheaper cameras, and don't even get me started on frankly most lenses available for 35mm cameras, especially stopped wider open than about f5.6 (when you see phase / 'blad files up close, you find a definition of 'sharp' that simply doesn't really exist in 35mm)
If you could, it would mean I could spend less on kit and more on holidays, hookers and blow. So I dearly wish that it didn't matter. But alas, I'm stuck spending on one single battery powered light, what my brother paid for his last car.
I disagree.
I have access to a Mamyia/leaf system with a IQ180 back any time I like. I hardly ever use it. Why do you think THAT is? Which of your clients insist that you use MF gear? And if they do... why are you not using it? Why do the images on your website taken with a D200 look pretty much the same as any of the others? Which of the images on your website required battery powered lighting that costs more than a car? Why you using that? Why not just a set of Bowens or Elinchrom lights with battery packs? Which single light costs £12K (average car price... so assuming that's what you meant)? Can you please tell us which of the images on your website required £20k cameras and high end lighting please? I had a look and I can see nothing on there that would warrant such expense.
Don't get me wrong.. some nice work on there, but nothing that couldn't be shot with pretty much anything.
However, I think you are missing the point Dave, you are talking about commercial photography, usually with a specific client brief and a desired outcome that will by it's nature have boundaries - and those have already been covered in this thread and pretty much agreed, even by those that prefer the art over the kit, that you need specific and usually expensive equipment for that brief and to be within those defined boundaries.
Over 20 year's worth of experience shooting commercial photography, and I see nothing on that site that would require such extremes. There's a range of gear used there that I can see... D200, D300, D3, D800... with nothing visible differentiating one from another. A mix of lighting on show but nothing that couldn't be done with relatively simple studio flash gear, some battery packs and cheap radio slaves.
The post misses the point of the entire thread any way, which is... are the images better as a result of the gear? Is anyone a better photographer as a result of the gear? I'd suggest not: The images taken with relatively modest gear on his site are not really any better than those taken with more expensive gear, so unless the client has incredibly stringent needs (and not many do in my experience), there's not really any need for it.
Good, solid, perfectly professional commercial work on the site Dave.. I'm not suggesting anything else... it's as good as any other commercial work you could find anywhere else.... You're in the right place, clearly networking with who you need to network with, and I'm confident that you will have a fine, and prosperous career.. of that I am certain... this is not in any way meant to be negative towards you. Of all the people on here, you're clearly one of the few that actually does good commercial work, so please don't get all personal... that's not professional. There's just nothing there that can't be created with fairly modest gear, and that is NOT meant to be a disparaging comment about your work. Your work is solid because you're a good photographer, not because you use fantastic gear.
High end MF gear is lovely, and an investment if you have a steady, high income from photography, but it's not necessary in the vast majority of commercial jobs. Also, you talk of things such as noise, and AF performance... both of which are not as good on any MF digital gear I've used. Appropriate tools for the job an all that... but it doesn't make your photography any better.
