Been wanting this camera for a long time, and wife finally agreed as a combined Christmas/Birthday present. Got the 6d and 24-105 kit from Amazon. Have only had a few hours to play with it, but I'm loving it. Previous gear was Canon T2i with 18-55 IS2 kit, 55-250 IS2, Sigma 30mm f/1.4 (great lens!). None of which will work with the new camera, so will be up for sale soon. Finding the 24-105 on full frame is a great all around range. (As a side note, I almost bought the 15-85mm lens for my APS-C. Anyone thinking of it, I think that too would be an awesome range). First L lens, and it's very well built. I cannot believe the high ISO performance of this camera. ISO 12800 looks much better than 3200 on my T2i. Cleaner and less blotchy color noise. Camera and lens have a lot more heft than my T2i. Going to take some time to get used to the different controls, and comfortable with the quirks of the camera, lens, and settings. Looking forward to the journey though! My only gripe so far is not related to the camera. It's that Aperture's raw processing for the 6D files SUCK! Lots of rainbow flecks of color noise, just looks awful. Out of camera JPEG looks much better. I'm on Mavericks with the latest updates to Aperture, so I should have all the latest RAW updates. Not sure what's going on. If I add the RAW fine tuning adjustment, I only get hue and boost. Sharpening, De-noise, Moire, etc are all grayed out. For my T2i RAW files, those controls are available. Anyone know what's going on? I'm going to have to try converting some raws in Canon's SW, or maybe give Lightroom a trial. Not looking forward to that workflow change, as I'm pretty invested in Aperture's organization. But these raw images are just terrible. Anyone have any suggestions? I can try and post a sample of out of camera jpeg vs aperture developed raw if it helps. (Actually, I should probably start a new thread for this question to avoid confusion).
