This is so funny to read. I have a 5D3 and a 1DX and there isn't a Nikon wedding photographer out there that has better IQ in their images. This all over a little DR in low ISOs. I have printed off prints from my 1DX that are 50 inches and they look great. What if Canon comes out with this high MP camera and much improved DR, is everyone going to come rushing back to Canon? All of this because of DR and more MPs so you can print billboards or corop down half of you picture. The D810 has been out for how long now?
Let's just say that you were entering the wedding photography scene today. Which system would you buy, Canon or Nikon?
It sounds like you're admitting that there is a slight difference?? The problem is that this noticeable IQ gap just continues to widen and Canon is either unable or unwilling to try and catch up. Wedding photography is just one application to photography. I'm a photojournalist and DR and ISO are crucial to my work.
People like myself are tired of waiting for that "what if Canon comes out with a high MP camera and much improved DR" question to materialize. A 1.6 crop factor 7D MII is Canon's big announcement of the year?? Really? It seems that Canon have forgotten their professional market. If I could get a decent price for my Canon gear, I would sell it and make the jump to Nikon today.
Well I have over 25 grand in gear so that is hard to ever ponder. If I had to start over I would choose Canon. I have had several Nikon second shooters so I have seen hundreds of their raw files. The only thing I can give Nikon is low ISO DR. It is much easier to recover the blown out highlights in a wedding dress for an over exposed image. But of the 1000s of pictures I take a year I can only come up with a few times I would need that extra DR. At ISO 1600 or above (where most of the wedding is shot) there is no DR advantage. High ISO is a tie, Canon has much better colors (I much prefer the skin tones from Canon), and Canon has better AF.
Canon also has great perfesional services and there are more lens options, better lenses and better availability. You say wedding photography is only one aspect of photography but it covers just about everything. Macro, arcitexture & Landscape, fashion and portraits, studio, action, and especially photojournalim in very tricky low light. Weddings really push a cameras capabilities.
So why would I change to Nikon for a little low ISO DR that I rarlely need? And for photojurnalist like yourself you are at high ISOs which doesn't have any DR advantage. Also why do you need more MPs for photojurnalism?
