Well, a lot of discussion on this very site is about use of older lenses which give their own advantages compared to modern lenses. Pentax has kept its mount for a long time and there is a great deal of bargains available in terms of older lenses. Of course many people prefer newer lenses, which Pentax is making but perhaps not at a fast enough pace. I guess the problem is that once you've been long enough absent from a market, people move elsewhere. But I do think Pentax has some advantages.
Their medium format has the same problem that most lenses are not modern and were designed for 645 full frame, not the sensor size that they're using in their digital MF cameras. However, if they want to revitalize interest in their brand, making a few good cameras is a good start. They can make new lenses over time. I certainly hope that they do.
