Here's a datasheet of Instax

Aerial lens can even provide 140-150° AOV, e.g. Russar-38/52/58/62/81/83

Cool, S-NBH53 is quite expensive.

Ah ha, only industrially produced chemicals are able to command very low prices I think. For example, customizing one or two piece of CNC part is really expensive, but once manufacture a large number of them, the price of each part will be affordable. IMO, besides laboratories, nowhere would use...

I don't clearly know about Amidol, but Glycin in China is crazily expensive as a type of chemical reagent so I can't try. Sad!

You can tell him to search "海鸥(Seagull) Planar" on https://www.taobao.com or in Xianyu APP. The text in parentheses is the English translation.

I don't really know about that, but you can check Light Lens Lab's site. However, it seems that their retailers in EU haven't sold this lens. Only one I found on AliExpress, $180.

Fig.4 Fig.5 I exhibit the overview about this modified projector. This machine uses a water-cooling light source because a semiconductor light cannot work in high temperature for long time or attenuation will happen. And yes, it's a Frankenstein now. In the red circle of Fig.4 is a 12V3A DC...

At least Osram announced in datasheet that a FHS lamp is able to produce 650 lm and EXR produces 925 lm. I will contact with Osram.

First, I quote a figure from Kodak 4400's manual. Even though I exactly use Seagull 4400L, they are basically approximate. Kodak authorized Seagull to edit and manufacture Carousel projector. And the first phase focused on replacing light source and adding wireless remote control. Fig.1 This...

cool😋

I'm writing now. But I need to find some information, pictures or drawings to recall details.

This thing is what I mentioned. It's about $85.5 in China. Front lens element for Rollei 2.8 is about $83.5. Some shop even manufactured or costumed Hasselblad Zeiss CF80's rear element and Canon Lsm 50/1.8's cemented lens.

Nearly all projectors use halogen lamp for lighting, and some of high-end products chose xenon. They are continuous spectrum and high CRI. However, no matter halogen or xenon, traditional lamps are hot and difficult to cool, and are also low luminance. Fortunately, advances in the semiconductor...

They even made a f/3.5 Planar lens block for Seagull, Mamiya 6, Yashica 124G and other leaf shutter camera🤤
