Id love to get an idea what people are using for their aerial mapping Canon cameras. I have the Canon S95, which usis optical image stabilization (OIS). This means the lenses are floating and move around in a very finite level to adjust for your hand movement. This poses a big problem for aerial work when the vibrations are noticeable. The lenses literally vibrate and no amount of shutter speed can fix it. I get very poor results; most aren't keepers but sometimes they are depending on motor rpm. Ive tested this camera for years on many different platforms, tried every vibration reduction method and still get bad results.
So, I'd love to hear what you are using and how the results work.

UPDATE: Ive ditched the Canon s95 in favor of a Sony NEX-5R with an intervalometer app. Ill be using a Sigma 30mm lens.

Best regard.
Currently I am working with the Regional Autonomous Corporation of Valle del Cauca CVC, and I'm working on the conservation of natural resources. I'm doing tests with a glider (SkyEye of HoobyKing) for mapping and to monitor some watersheds, acquired a Canon S100 Camara and surprised the work you did in Peru, I would ask for your support so that you sent me the version of CHKD with the script you use to take these photos as menu configuration instructions of camera manually. I have already made flight tests with Mission Planer and APM 2.5, achieving autonomous flight and fire the camera automatically at each waypoint.
Thank you

Hi
It is the first day of 2016 today and there must be some progress in this area. I wonder what are the hot cameras in the topic today? Are people still using NEX5 and EOS-M ?
I am using 450 sized quad running on APM 2.6 using a cheap Canon 2300 point and shoot camera to do photogrammetry after following step by step guide on flight riot. Result is great without any blur or underexposure.
I am flying on 100 m Above ground with averagely 18Km/h horizontal speed.
Series of photo taken first stitched using ICE and then doing 3d reconstruction using Visual SFM and CMVS.
Fist trial, i was using ISO overides on CHDK as Canon 2300 doesn't have manual or semi automatic function (Aperture or shutter priority). I thought the ISO overides will force the camera to use higher shutter speed to generate a more steady picture, but i ended up with an overexposure photos. Then i re try using an auto function without any overides. The result is great.
Matt Gunn how good is the intervalometer app from SONY in mapping the ground and do some photogrametry?
I'm almost buying a a5000 and start using the app but i really need to know if the results are good, if it works using AUTO mode (Or any other mode) and if every single photo are focus. (i read some old posts regarding the app that says the app only focus the first picture and the next one are unfocus) :X
Thank you!
Hi David,
But since i'm used to start shooting before the drone is in the air (Currently using a Canon SX260 with 3s interval between photos, 1/1000, ISO Auto, Continuous Focus) wont that Manual Photos shoot the first photo and the next ones gonna be unfocus?
For example the first 10 photos taken are from the ground (0m) to the altitude desired (100m high).
Can i see a photo from you Nex 5t to see how sharp it is?
In attach is one taken today (very cloud and no sun at all).

Holy crap man.
I really hope the a5000 pictures quality (somewhere between NEX 3 and Nex 5) can be very close to that.
So the trick to manual focus is so simple! lol! Thanks man.
But is possible to shoot in AUTO or the results are worst than Manual?
I've produced several very accurate models (DGPS controls GCP RMS error <17 mm) with images from several S100 at 1/1000th second Tv; The minimum usable shutter speed will depend on flying speed/altitude, but I don't think it always has to be faster than 1/1600th.
Do any of the NEX models have an intervelometer?
