I adjusted my focus!

[OnTheRopes]

Here is an example of the difference between sharp and acceptably sharp. I am planning on changing the lens on my GoPro 3+ to the Peau Productions 3.97 mm one. I was always happy with the sharpness of the existing lens but wanted a narrower field of view and less fisheye. My new lens should arrive soon but in the meantime, I loosened the old lens and tried refocusing it to see if there would be any improvement. You can easily see the difference. The original setting on the left and refocused on the right. These are 100% crops from the full size and were taken about a minute apart.View attachment 1730
Using a hyperfocal distance close to the camera will give an acceptably sharp image at a distance, but if most of what you are shooting is at a certain distance, then you should focus at that distance for maximum sharpness. Objects which are 6" from the camera may be out of focus now, but I will never have my copter that close to something.

The difference is quite distinct, I always thought my lens was focussed too close, despite somebody on here insisting that if you focus at 6" everything will be in focus, that was clearly not the case.

You mean CGO3+ camera, right ? because you keep posting GoPro 3+

Actually I did mean GoPro 3+. My CGO3+ camera is at Yuneec for service for a different issue (vertical lines in the highlights.) I am doing some lens focus and replacement tests on my GoPro 3+ in the meantime. I will be using the GoPro 3+ and my GoPro 4 on my quadcopters now with two different focal lengths.
This example was just to show the effect of a bit of focus adjustment, which I think might be the issue with some Typhoon cameras.
I just received the Peau 3.97 mm lens today. I will wait to see the results of service on my CGO3+ before deciding if it needs adjustment or a different lens.

My very first CGO3+ camera had that problem as well as the issue of placing dancing blue & white dots throughout the image. I documented this in a YouTube vid.

Sensor is safe from the glue UNLESS the lens is totally removed from its base.
Few ways to deal with the lens glue when removing it but an easier way is to run a vacuum cleaner as you cut it away to suck the loose **** off.
To adjust the lens to suit your needs, the best way is to connect HDMI to a big screen and watch the screen as you turn the lens. Even better way is to find a focus templet and print it on an A4 sheet, place it whatever distance you like and watching the big screen...turn the lens until the template looks clean on the big screen. Very easy process. BUT BE CAREFUL AND TAKE UR TIME stripping the camera body. A sharp razor blade works perfectly to remove the Glue.
Once u find ur focus point, u can run some glue where the old glue was to stop the lens from vibrating out of focus OR if ur keen enough, unscrew the lens completely and run 1 tickness of thread tape around the lens thread, that will keep it secure and be enough for u to adjust it for ur focus point by hand.
Another tip is to mark the focus point so that in future if u need to do work in there again, u will know where the focus point is when the line u drew lines back up

Were you a battleship sailor..

HAhahaha no... I was there the day the Mighty Mo came into Sydney Australia and did a huge broadside, so the vision stuck in my mind and is one i never want to forget. So i found a pic of it and used it here.
I was lucky enough to go on board the ship thanks to a returning drunken sailor who we managed to con into getting us on board. He then vanished out of sight (we guessed he s nackered (stuffed) and went to sleep) so we wondered around the ship until we were confronted by a MP with his gun pointed at us asking us why we were in the restricted zone. That was a scary moment indeed. after we explained the story he escorted us off the ship. ( had my wife and carrying my son at the time)
But on the superstructure we saw the damage those guns can cause as the toilet room was shattered into pieces and the door was buckled. They told us it was because the door was left open before the broadside took place. To this day I am not sure that's what caused it but its a great theory and i have stuck with it for decades

I've been saying this sine these discussions started. If anything is infocus past 6 inches EVERYTHING will be in focus past that. What people are perceiving as "Soft" is low resolution

I noticed frame speed

Oh my gosh, what a story! That looks like the Battleship Iowa. I was on the ship at the time of that shot that you have in your profile. I was a Radioman between '83 and '87. I have a FB page that is full of the sailors that served onboard... www dot facebook dot com / groups / USSIowa/.

Well unless i got the wrong shot, its the 63 mate. Mighty Mo herself. If i recall correctly, it came down under to celebrate our 75th anniversary. Do not quote me on that.
Oh and for your service.. I thank you for our freedom today

Wow, nice footage!!! Iowa, Missouri, Wisconsin, New Jersey are all twin sister ships of the Iowa class. To keep this a drone subject, I am going to look for the drone shot of the Iowa.

The ex- Iowa sailors on the FB page said yes, that is one of the Iowa broadside shots. Hey, only the actual sailors would catch something subtle like that

Yeah It was a great time .... I was serving in the Navy at the time and was onboard the lead ship for the harbour entry shown in the video (HMAS Perth - DDG 38).

Mighty Mo was certainly a sight.

Cheers

Ph WOW sensational to watch that. Thanks heaps
