This is a serious question, just not a gear slut who's bored.... Business is well and i am looking to the future. BACKGROUND I have a video production company. You can see my work here: http://www.youtube.com/mazomedia I seem to use the 28, 40 and 55mm the most of all my lenses. As you can see in my videos, I do a lot of handheld. I am a one man crew, so portability and ease of setup is key. CURRENT GEAR (for context) - 5dii & T2i - 28mm, 55mm, 135 Takumar Pentax lenses (adapted) - Canon 40mm & 18-55mm w/ IS - 2ft slider w/ motor - Aluminum manfrotto tripod with fluid head - Rode video mic pro (because plural eyes came with it) - Zoom H2 audio recorder - Seinhausser G3 Wireless audio - Zucutto eye view finder for 5dii - 128 LED light (battery powered) - Reflector And a 12 core computer with 32GB ram, SSD's and 10TB storage. WHERE I NEED HELP Like I said, business is good and I like to invest when I am a little more flush with cash. My next camera will most likely be a C100 (I'm sure about this actually, so let's not talk bodies). I feel that lenses are the way I should head right now as I have most of the "tools" (sliders, audio gear, computer). I have my eye on: - Zeiss' 50mm F1.4 right now as I love the contrast, tone and sharpness of the lens and I use manual focus only. When I use 50mm, it's always on a tripod - Canon's 28mm w/ IS as I go hand held alot. (but depending on the Zeiss 50mm, I might go with Zeiss 28mm) - Canon's 24-105 F4 L-series looks appealing only because I have a lead on a factory fresh one for $800. What are your thoughts? THANK YOU!!!!
