Ossie, I was originally planning to use the DNG converter, but as that doubles the number of files I had to keep track of, I opted for LR6.
Sury, yes they do, but the camera I purchased is a Panasonic and so is not compatible with the Sony only version of capture one.
Peter, After reading the first two paragraphs, I expected to see that you were still using Windows XP.
Like Sury said, if you stay with Sony there's a free version of capture one. I never could get used to it though. And as Ossie said, there's a free DNG converter that Adobe offers and you should be able to edit those files in LR4. You just have to add one more step and then either store twice as many files or delete the raw files once converted to DNG. But I'm with you. I can't stand the rental idea for software. Just let me buy it.
