IkarusJohn Posted November 29, 2011 Share #1 Posted November 29, 2011 Advertisement (gone after registration) I've been playing with video using Leica M lenses on an APS-C sensor camera. I'm no videographer, but I've found some things that might be of wider interest. With a 1.5 crop, your lenses become effectively longer (15->22; 21->32; 35->52; 50->75; 75->112). This means that camera shake and vibration becomes more critical. It's really about wides. Also, with longer effective focal length and smaller sensor, depth of field gets shallower. No zoom; you only have primes. You do get to select your aperture directly, and manual focus is fantastic (with peaking focus confirmation - it's very nice). With a fixed focal length, you need to be careful about point of view. It can become very static, and if you move, it can be jerky. So, I'm finding that old fashioned planning with pencil and paper, thinking ahead and staging each shot segment becomes more important. Using an electronic view finder (rather than the LCD screen) makes a huge difference. With a reduction from 16 MP's to 2 MP's, I'm not confident of the quality yet. But, for home quality 1080 HD, it actually looks like it will be lots of fun. Cheers John Link to post Share on other sites More sharing options...

ezc203 Posted November 29, 2011 Share #2 Posted November 29, 2011 Which camera are you using? I've often flirted with this idea in the past. I wanted to shoot a short film on a GH1 (or whatever the most current model is) and a set of 24, 35, 50, Summilux lenses. But eventually the practicality factor just put me off. Pulling focus on such a petit rig is just too much of a pain. Also, these Leica lenses (as amazing as they are) are not built for video and it shows: lens "breathes" too much, focus shifts when changing apertures, definitive aperture settings as opposed to a fluid ring, etc etc. Link to post Share on other sites More sharing options...
ezc203 Posted November 29, 2011 Share #3 Posted November 29, 2011 But to be completely honest, I'd still love to shoot something on the NEX7 with a set of Leica-M primes. Just for the experience. Link to post Share on other sites More sharing options...
IkarusJohn Posted November 29, 2011 Author Share #4 Posted November 29, 2011 NEX-5N. As both the NEX-5N & the 7 have the same sized APS-C sensor, you really need to use the wides. As Steve Huff established pretty appalling colour shift with Leica wides, I went for the 5N. Cheers John Link to post Share on other sites More sharing options...
