No, I will not be an early adopter. In fact, I may not buy this camera at all.
I was never convinced the Ricoh/Pentax should build a full frame digital camera, and my opinion still hasn't changed. I do hope it works out for them but I am afraid that it may turn out to be too little, too late. I will look at the camera with great interest when, and if, it finally arrives on the scene.
Although my *1stD and my K10D are a bit long in the tooth now, particularly in digital terms, they still provide some excellent photos when I make the time to use them, which isn't all that often anymore. They also happen to be great handling cameras.
The Q and Q7 are now my primary digital cameras, and I find it wonderful to carry and have made some amazing photos with it. I was a very early adopter of this system and have never regretted it.
I also recently purchased a new 645D and am having great fun rediscovering all my 645 lenses. This has become my primary portrait, landscape and art camera. It took me quite awhile to buy into this system because of the upfront cost but, again, I am not sorry I did.
There was a time in my life when I did feel that full frame was important. But since the Q I have changed my mind. Additionally, since the 645D handles the majority of tasks I would consider a full frame for, there is no longer a reason for it.
I am sure that those who have lobbied for so long to see this camera will enjoy it.
Assuming of course that they actually step to the plate and buy one that is. Seems to be an awful lot of waffling out there all of a sudden.
