I'm running a NEX-3 with plans to upgrade to a NEX-6 this year. I'd like some recommendations on MF Primes. I do travel photography, event photography, model photography, and timelapse and brochure video work. In addition to the e-mount 18-55mm kit lens and e-mount 35mm prime, I'm thinking about getting a Pentax MF 50mm f/1.4 (portraits) and Pentax MF 135mm f/2.5 (sniping at events). What do you guys think? Background Story Ever since I started shooting in high school, I obsessed about getting a full frame DSLR. Eventually, I got the Nikon D700 + D200 and a collection of niceish glass to go with them. For a long time, I had ran a modeling and wedding photography side gig and those cameras served me well. Since getting the NEX, I've been selling my Nikon gear off and all I have left is a Nikkor 50 F/1.8 and some mid-range zooms.
