I have been a Canon user my entire life. I love the product, including DPP which is my RAW converter of choice.
I presently shoot with a 1D Mark IV and a 5D Mark III, which are fully supported by my present version of DPP. The 7D Mark II requires that I update my DPP.
Here is my problem with that.....
The newer version of DPP does not support my operating system. I run Vista 64. Updating my operating system requires that I go to Windows 8 which needs a clean install. Huge job. Also, I'm not sure that a lot of my current software will run on Windows 8. I have CS4 as well as plugins such as NIK, Neat Image and a slew of other free standing applications.
As much as I was not comfortable with the user interface of Lightroom when I tried a demo last year, I thought I would now have to go that route. Guess what? Right. It's now only available under CC and I refuse to rent software on a monthly fee basis which is why I still run CS4.
I'm 72 years old so I guess my 1D4 and 5D3 will have to do me the rest of my life or until my computer cr@ps out and I have no choice.
All Canon had to do was continue to support the operating system and I would have added a 7D2 to my bag.
Okay..... rant over.
