The debate around Mirrorless v the traditional DSLR is an interesting one. I was very much involved at the time that film was switching over to digital in 2002/3 where my publishers were still asking for colour transparency film as it was easier to do colour separations for high quality magazine work, So I held off for a while sticking to my medium format film cameras before I embraced digital fully.

I see the same debate happening again, and even though I am really really committed to my "Mirrored" cameras I think that eventually this new format will win out in the end. The one turning point will be when there are sufficient connectors to allow users to use existing lenses or manufacturers make the bodies capable of accepting these lenses, and I think the other will be when some of the big name photographers and mainstream publications broadcast widely that the images within the publications were all taken with the newer technology.

I have both, but still use my traditional DSLR 90% of the time at this stage. Time will tell.
