Yes, I wondered that too, but was going to let it go. ;-) The base I fly near has little security patrol boats (with machine guns posted on the bow), and they travel all around the surrounding waters, sometimes "communicating" via loud speaker. So I figured I'd give him the benefit of the doubt.

Threatening a civilian standing on private property 1.5 miles from a base with "deadly force" seems outside normal protocols. "Land your drone or we'll take it down" maybe... So you've got a hot head patrolling there. Beware. The advice above to establish a relationship with the local...

Now I'll have to go back and look more carefully to see if maybe I just missed it!

Mine is called "Olympus M.Zuiko Digital ED 12mm F2.0 Lens, for Micro Four Thirds Cameras (Black)", currently $699 on Amazon (drat I paid more when I got it back in early 2016!). https://www.amazon.com/gp/product/B00MCWSQZU/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

No. I would not say that my 25mm is, quoting your post, "blurry near the left edge wide open and it only got better past f5.6". The lens sharpness seems to follow a pretty symmetrical sharpness curve, from sharpest in the center, to less sharp as you move toward the edges on each side, at...

Yes, I was being intentionally vague when I typed my response above and said both the 12mm and 25mm were sharp "at f4 through f8 OR SO" because the specific settings I use in any given situation vary. In most aerial situations I try to shoot stills with my 25mm at f5.6 or 7.1, ISO 100, and a...

My experience is the same, except that my 15mm is a poor performer all over. I never use my 15mm. Other threads here suggest that there's a wide variation in build quality, and that some lucky people have good instances of it, but they seem to be in the minority. The majority of my shooting...

Thanks for sharing. Very ambitious project. I can see what you were after and how things didn't quite pan out as hoped due to the flight inaccuracies. Still a fun project, and an effective result.

Thanks for adding your experience. Yes, the fact that Litchi turns the whole bird instead just the camera is very disappointing. It is especially awkward when using it to shoot 360 panoramas, IMHO, since the I2 is so big; That's a lot of mass to try to spin around the no parallax point! ;-)...

Nicely done.

Hi Frank. A minor heads up re Litchi: I have a fair amount of experience using Litichi to execute the same sorts of exactly defined missions as you describe above, flown with my I2, and it works very well except for one frustrating intermittent problem: Gimbal Yaw calibration drift. Basically...

Not sure why AABM has used past tense here. Most pros still use UV filters to protect their lenses. In the visual light range, good UV filters behave like clear pieces of glass. They don't impart color casts and don't make footage look washed out. I'm a long time commercial photographer with...

It is trivial to automatically crop an arbitrary number of images to 3:2 in a single step in LR. Check out these LR features: Sync, Develop Presets, and Apply a Develop Preset during import. I always shoot stills with the natural aspect ratio of my camera's sensor. I see no benefit to having...

Litchi is an automated piloting application that I use for controlling my I2.One of the things it can do is automatically capture a set images used to stitch together panos in other applications. It can also capture brackets for HDR processing in other applications. So it is complementary to...

The comparison seems a bit apples and oranges to me, although with a small overlap. With the Insta360 you can capture true 360 video and stills, both for 360 playback and for reframing the 360 footage into standard video in post. I've done this with both a Insta360 and a GoPro Fusion hanging...
