Although you can use crop mode on a FF, but then it is not a FF anymore

I can't believe I didn't know my Nikon FF had crop modes. For video it has a 1.5 crop option (it has 1.2 and 1.5 for photo), and still fills 1920x1080. I'm seeing things I've never been able to see before. So cool.

Beautiful imagery. Thanks for sharing this.

Wow. First, nicely spotted! The video is just beautiful.

The 2 side covers are only held by 4 JIS screws. Nothing optical is affected by removing the plastic covers. Check both slotted set screws are in place,if they are both there one may have sheared off the bottom end. The thread is maybe 2mm so it wouldn't be that hard to break. It's worth checking a...

Too many guess work suggestions about grease and crush washers. That's not how they work. I have a few of the Nikon binocular heads which are easily serviceable. Attempting the suggestion about tension washers will only result in a broken front cover cap. Thanks. I'm leaning toward doing nothing. I...

Just curious. If you just lift the right eyepiece tube, does it just drop back down? If by "lift" you mean swing counter clockwise to spread it away from the left eyepiece, then yes, it drops back down. Without the eyepiece in the tube, it drops more slowly than with the eyepiece in the tube, but t...

If you haven't found the answer to this yet, please give brand and model number of the scope. More help may be available through personal experience of others. This is a Nikon Diaphot Inverted Tissue Culture Microscope, circa 1985-ish, with a Siedentopf-design binocular head built onto a die-cast b...

Absolutely beautiful images.

I had this problem with a new scope once. It took a while for me to find that tiny screw on the occular tube which needed tightening. Take your time. Look carefully.

Thanks, I'll go through it carefully. Appreciate your input.

Thanks for that detailed answer. I'm a newbie with a microscope so I'll have to figure out the best way to get to the parts you mention to see what may be wrong. To answer your question, I don't see a crack, but I haven't taken apart anything to look behind other pieces. There is a slight wiggle of ...

I didn't know what it was at the time. I recorded about 41 minutes wondering if it would break out. Finally gave up since I had no idea if it would be minutes, hours or days. There were a few active periods, and the only real movement of the egg you can see in the video -- what you can't see at 10x ...

Hi. When I spread my left and right eyepieces for my proper viewing width the left side stays still but the right side slowly drops all the way down due to gravity. I have no idea how these are constructed so I have no idea if I can tighten the right side or increase friction. This is a very old Nik...

Gastrotrich inside an egg. Footage sped up 10x. Brightfield, followed by some phase contrast at the end which shows nice detail. 40x objective.

Any idea what this is? Taken through 40x objective. At times (especially later in the video) there appears to be a faint flagellum. Note I slightly sped up the video 1.5x. From a freshwater sample of ground/flood water.
