Hi Guys,

Here are some photos showing the production version of the SGblade with the new Rods Support System. We are getting close to shipping the first batch :D

Comments Welcome :)

Wayne.


It appears that the elves have been very hard at work in the dungeon. In appearance and presentation you have done well, a visually attractive package.

Out of curiosity, do you continue to recover a relatively large piece of the image area of the still-camera frame?

Thanks Bob,

The Image area is 36x20, which is full frame in 16:9.

very sexy! I want one!

36mm x 20mm. That then puts you in the possible realm of 35mm into the SI2K if the resolution from your groundglass holds up as well as the evenness of light across the groundglass to the wider sensor.

The angles of incidence at the far edges must be a bit steeper than for a 1/3" sensor. There seems to be more of a tendency for brightness falloff for the same field of view of the groundglass.

45mm relay seems to be about the most predictable across a range of stills lenses for relay on the Letus Extreme and may hold true for your adaptor onto a 2/3" single sensor.

I was ponderting this, and I thought we may not notice it as much on 35mm film cameras because film has a wider latitude. Does that make any sense ?

My guess is that the crystal grain structure of film emulsions has something to do with it. Each grain has multiple facets, one of which must face almost directly towards the incident angle, therefore harvests the light more effectively.

I also guess this is why there is the "grain" structure evident in film image when it is blown up enough.

Some crystals in centre do not take such a light hit head-on as others.

This might explain the ability of film to see deeper into blacks and tolerate over-exposure, film maybe having an inherent multiple ISO rating in its structure rather than a single number

If each pixel was a multifaceted diamond shape a sensor might work more like like film.

My wild imaginings here, no proven science whatever.

I was looking at some meduim format paper printed portrait enlargements yesterday from the seventies. That stuff was good wasn't it.

I keep looking a my Kowa 6 sitting on the shelf, not getting any use, and wonder about building an adapter to use those lenses. Alas, I think I have enough problem keeping a 35mm lens in focus, that with the 6x6 lens, it would likely be a real bear...., and a heavy rig at that.

Wayne, what kind of price will that elegant piece of kit be going at?

Hi,

Online ordering and full pricing info is on our website.

Regarding the Kowa lenses.

You may be already aware, Ted Ramasola has already been there done that with medium format via a home made adaptor and one of Wayne's achromats.

The larger format gives you a distinct apparent resolution gain through scaling the "grain" smaller relative to the frame size, even if you have to sacrifice some of the image area to get inside brightness falloff.

I think the limited lens choices moved him back to 35mm stills Nikons. He kept his options open by making his adaptor dual format.

Hey Wayne those look fantastic! I really love the colorway.

How soon before they ship Wayne?

Look sexy as hell!

Hi Phil,

Hope to get them out the door next week :)

it's like waiting for a kitten or puppy to be old enough so you can take it home!

Hope they are house trained!
