"Fyi - here is quite a bit of spectral response data from MaxMax.

Knut Graf replied to Benjamin Meltzer's discussion NIR Camera vs RGB Camera Conversion in Agricultural UAVs
"You can get quite far with converted normal cameras - the advantage is that all the r&d that goes into "regular" cameras works of you, if you go that route. If you compare the converted cameras that you get, for example, at MaxMax, to a dedicated so…"

Knut Graf commented on Jeff Taylor's blog post New NGB Filters and Higher Resolution Camera at Event 38
"Thank you. I'm working on an NDVI processing software. Maybe I can build some software presets that take the imaging characteristics of your new filters into account."

Knut Graf replied to Knut Graf's discussion 30 minute multicopter flight times, with a camera, in practice ?
"Friends of mine are working on a quad with 400kv-class motors and 17 inch props, running on 6s, and they are achieving 30 minutes with camera on gimbal, I have been told. I will updated once I learn more."

Knut Graf commented on Chris Anderson's blog post PocketDrone -- new APM-based Kickstarter project
"This looks like a smart design. But does "heavy lift" go together with "Capable of carrying up to 1/2 pound payload" ?
The term "heavy lift" is often used for rigs capable of carrying DSLRs and professional movie cameras. I suppose given the low air…"

Knut Graf replied to Ahmad Affiq Bin Sukari's discussion APM + OpenCV
"I have been looking at a similar use case, where a copter could LAND on a visual target, based on control inputs generated from computer vision on an onboard camera. That would be an amazing transitional-technlology capability, useful for deliveries…"

Knut Graf replied to Kevin W's discussion 3DR Iris vs Phantom 2 Vision
"The Phantom Vision 2 flight time is real, and it's hard to beat. The system is light, and the components are well-matched.
There is a good amount of Phantom community support (on other sites), but the Diydrones community is exceptional.
The software…"
