I own a SONY PMW 350K, DSR 450 and DSR 570 and i use top end SD Fujinon lenses of my other cameras on the 350. Yes the lens on PMW 350K is cheap but very very good in HD mode. It shoots great pics better than a top end SD lens when shooting in HD mode. Only problem with kit lens is the zoom, it gets a bit jittery. The best way iv’e found to use SD lens on the PMW 350 is by installing CBK-DV01 SD Record and Playback Key for PMW350. I installed it my self its easy just a couple of screws, a bit scary when you open the camera up it looks like a computer inside. With the card added the camera acts like a normal SD camera and the pics are just beautiful when using top end SD lenses. I use a nano flash connected via SDI for 4.2.2 uncompressed and still a great choice if you only have 4.2.0. color spacing and lower than 50 mbps bit rates. When shooting HD i use the kit lens and try not to use the zoom much. I love the PMW 350 it is an awesome camera for the money. The colours are very vibrant and in low lighting its great. I have shot a few hundred hours on the camera and not experienced any of the problems related to CMOS sensors, panning, fast movement etc. I have noticed banding with camera flashes but no big deal. Sony has done a great job of this camera. It has USB, copy data backward and forward to the Sxs cards, 24p, under crank, over crank, time lapse, Unbelievable audio and colour settings. The camera pics are too Sharpe and need to be adjusted down, sounds weird aye too Sharpe.
Hope you enjoy when you buy. Pat
