Chronos User Discussion / Re: Focus adjustment
« on: December 19, 2020, 07:51:21 AM »
AHHHHHHHHH!!!!!
I didn't realise there was a spacer on the 'old' Fotodiox, so when the new one arrived I just replaced the whole thing.
Now I've managed to get the spacer off and put it on the blue Fotodiox and it's fine after a little reacalibration.
Thank you

Chronos User Discussion / Focus adjustment
« on: December 19, 2020, 02:39:41 AM »
I'm using exclusively Nikon-mount (Tamron, Sigma and a couple of real Nikon) lenses with a FotoDiox 'pro' adaptor (the one with the blue stop-down ring) and have been having focussing oddities so I decided to try out the back-focus adjustment as detailed in the manual.
I started turning the mount with the lens focussed on infinity and pointing at a remote tree as described. I turned it and turned it and turned it and turned it. It was getting nearer, I could tell, but it was sticking quite far out of the camera now and when it was very near (but still not right) there must have been a whole centimetre of thread visible! I thought leaving it like this might not be a good idea, given the weight of most of the lenses and the strain that must put on the mount, so I put it back in again and gave up. I'd rather have erratic focussing than a broken camera.
Was I doing something wrong? is there another adjustment I can make or a shim I need to put in place to get decent focussing - or even a different Cmount to Nikon adaptor? My main problem at the moment is the 'infinity' is at the point marked about 2m on the lens, yes really, and I can't get very close to anything with it in focus.
How are other people with Nikon lenses getting on?

A little slow-mo humour I managed to capture this afternoon. Bird startles friend

Several minutes sounds wrong to me too; like Nikon1, my 2.1 boots up in around 42/3 seconds. Not quite as instantaneous as a DSLR but quite an improvement over the hour or so I heard Lauri mention a Phantom can take to set up
If your camera really is taking 5 minutes to boot up then you might have a faulty SD card so, installing a new one (especially, if you just have one lying around) *might* at least get you down to 'normal'.

I'm just buying old Nikon lenses. There are loads available on eBay (I even got one really cheap cos the autofocus was broken!).

Ahh, another good find.
It would be hugely helpful to be able to use sensor gain at those settings higher-frame rate settings - especially as the sensor analogue gain does seem to work really rather well (at least at lower frame rates). My budget doesn't quite run to another 300d at the moment

I think it's a bug, I'm having similar problems with some combinations of resolutions and gain - though I didn't test as thoroughly as you did!

With the help of Nikon1 I managed to make my Chronos record with different fps in one shot. Fastest was 1000 fps, then 0.1 fps.

Oddly, I also got hold of an "Intensilo" battery - and that fits fine!

It's very subtle, but it looks like the distance between the edge of the battery and the contacts is slightly (like a fraction of a millimetre) smaller on the Nikon battery. I tried putting the battery in with some packing on that side of it to move it over but without any luck.

Hi,
I got hold of a real Nikon EL4a battery, but it doesn't fit in my Chronos 2.1HD! it goes in the compartment, but doesn't seem to engage with the contacts and the door won't close. Any ideas?
