Re: Just got the LS300 camera - very happy so far
 

A advantage of the ls300 is that you could zoom with a 25mm lens and give it a more usable focal range but there is something to consider, not sure how much you exactly can zoom in but lets say you could zoom in up to 50mm on a 25mm prime lens at f1.4, important to know is that a 50mm prime lens will give a shallower dof at f1.4 if you don't zoom in to get the same focal length. Zooming with a prime lens changes the focal length but not the dof.

I love the the prime zoom feature as it gives me more options with a prime lens while retaining the same aperture which even good zoom lens can't do. However there's a small side effect which I can notice and haven't made decision if I care or not. All zoom lens will increase the DOF as you zoom in but with the prime zoom feature the DOF stays the same which gives a flatness to a live zoom. Adjusting the zoom between shots of course isn't noticeable after editing.

Steve, I use the 12mm MTF mount with the VSM set to 86%. I find there is bit too much light fall-off at the frame edges when using 100%...but I wouldn't hesitate if I needed a really wide angle shot. At 86% there is very little distortion and is plenty wide.

I love the Samyang T1.5 35mm in EF mount and use it a lot, along with my Canon 50mm f1.4 lens. Will be getting the 85mm soon!
