Re: EL Nikkor+Fujifilm GFX

As an add-on to what FotoChris has already said. If there's one thing I've learned from doing tests over the years on enlarging type lenses? Results will always be best staying within the designed parameters of the lens. Outside that aberrations will be an issue. All the 6 element 4 group 50mm, 60mm...

Re: EL Nikkor+Fujifilm GFX

Hi Cunha, While I don't own one of these, there are 4 versions of the 63mm I'm told, coverage would depend on how you are using it, for reduction or magnification? The coverage would be less setup for reduction. I just re-read your post, so for enlargement, looks like it should cover the GFX sensor ...

Re: Safe objective cleaning solution -- so much conflicting info online?

For sensors there are special lens cleaning fluids available (Eclipse) but there are a lot of people who use isopropanol or ethanol even on very expensive sensors. Personally I'd just give the camera to a store for cleaning, it's not expensive, they're fast and it's safe because they're insured. Be...

Re: Safe objective cleaning solution -- so much conflicting info online?

Lens 99% of the time I use a Microfiber cloth and or lens pen. This is what people at the factories I visited used and recommended. 1% of the time I use a solution applied to a cloth, not directly on the lens. I've used this product before. They sell 4 different types of solutions. https://www.lensc...

Re: BD Plan APO 0.8na, require surgery or can solvent also be used?

On the last few projects with stuck threads a little heat does wonders. Last time was an APO-Gerogon with a stuck adapter, tried everything then put the lens in front of a portable space heater for 5 min and the treads loosened nicely. Try it. My friend has a machine shop and swears by this method. ...

Re: Nikon to Acquire US Cinema Camera Manufacturer RED.com, LLC

Another factor, Red has full access to use Canon's RF mount and uses it with full autofocus. So maybe this might have happened so Nikon gets access to all of Red's technology including all Red's patents.

Nikon to Acquire US Cinema Camera Manufacturer RED.com, LLC

This is a surprise, I wouldn't have believed it if I didn't see the release on Nikon's own site. Just two years ago Nikon shut all their last remaining lens factories in Japan, including the biggest one, and closing subsidiaries. Now Nikon is making aggressive moves. Recently they announced they are...

Re: What features and comforts would your hypothetical dream camera system have, based on your needs?

40 x 40 or 44 x 44 square sensor would be great. Zebras. All analog style dials. Camera button function and control lock (Nikon has or had this). Arri rosette and NATO rails connection point all over the body, like a camera cine cage. Removable viewfinder. RAW histogram. Highlight priority exposure ...

Re: Mitutoyo 10x 0.42 M Plan APO HR lens adventure

If you watch closely, you can see in each video that the barrel of the objective has several small holes that are filled with white stuff. I've been told that those holes are used to provide access for pins that push one of the lens groups into perfect alignment with the others, before adding the w...

Re: Mitutoyo 10x 0.42 M Plan APO HR lens adventure

I bought a used Mitutoyo 5X HR in 2022 that had been taken apart previously for cleaning. It was as sharp as it should be in the centre but outside the centre it was quite bad. I got refunded most of what I payed and kept it, but in hindsight I don't know if that was a good idea, I might aswell hav...
