Finished 35mm Adapter Stills

So I went out today and shot some random footage at f1.4 with my 50mm Nikkor lens. There's some grain, there's some softness (from camera movement, largely, but also just from resolution loss), but whatever. The parts used cost barely 60 dollars, so I'm proud to have finished something that works. No CC except a tiny contrast adjustment, by the way.

These were taken at noon (worst time to shoot) and I can definitely say that there's an improvement in dynamic range with an adapter. At first I was skeptical of these devices, but the plusses are amazing. When you consider that the hard edges, chromatic abberation around highlights, low dynamicr range, and depth of focus that give away cheap video are all cured, there's no reason not to get one. Overexposure looks much more acceptable. Shooting upside down is horrible, but the improvements a good adapter can give are astounding. Unfortunately, this is a cheap home-built adapter, but I'm totally sold on the concept now.

By the way, don't bother to build one for use in a real production. No matter how good it gets, it'll be worth it to get a professionally built one. I've worked so hard to reduce distortion, grain, and vignetting and increase resolution and low light ability and gotten no where near what a professionally-built adapter would give and the device itself is sturdy but a tad clumsy and only works in 16:9. Both the M2 and G35 have extremely thin focusing screens and that means very little light loss, good resolution, and less grain. I'm planning on getting one as soon as I make a little more money and the verdict is in on which is best for my needs.

I'll post more later since I'm hoping to have a little fun with this before school starts.
 
Yah dude, definately make a quick little short with this before you gotta rush off to school (junior year in highschool for me starts on monday)

I mean, why the hell not, you put all this work into it. Great results by the way, but yes, I agree - by your admission it doesn't come close to the "professional" ones... then again yours cost 60 bucks in supplies and theirs ... well I know they're selling em for around 1k, so ...

What I'm trying to say is - NOT BAD for sixty dollars!
 
please please please please please please please please please please please please please please please please please please

list your parts, both from the stepdown off the leica, to the actual lense you use pleaaaaaaaaaaaaaase!
 
Okay, this is equal parts pathetic and really pathetic, but I don't want to waste my 1000th post on something in this thread (rather post something cool with it!) so I have to delete a post every time I post something to stay under 1000! So....I'm going to reply to messages with edits to the first post. Yes, I know I'm crazy.

Monte, you're only a junior in HS? Not bad. The screen grabs you've been posting are really solid. When I was a junior, I was making terrible movies about people peeing on stuff. Well, that really hasn't changed much. Keep it up, though.

Lucidz, unfortunately this isn't as simple as my original 35mm adapter. It's cheaper, but not as simple and it requires quite a bit of dremelling/drilling. Also, the focusing screen is made with capillary action and wax which is a pretty huge pain to work with (the layer is as thin as a piece of scotch tape, by the way and light loss is not as bad as you'd expect.) Now, if I can find some microcrystalline wax that actually works (the stuff I have is giving me major grain so I'm using beeswax which is hard to work with), then I should be able to make focusing screens for really cheap and ship them out and they should be nearly as grainless as the G35. Also, if I can make a few tiny adjustments, I'll be able to use this thing in 4:3 mode, but as it is now, the ground glass is just a few mm too small.

As for a parts list, here's a rough guide:

(The nubbin on the left side of the image I remove.)
Three pieces of PVC pipe, spraypainted black. One has the f-mount mounted on it with screws from eyeglass repair kits and JB weld.
Two microscope slides cut to about 55X26mm and mounted inside the middle piece with JB weld.
This piece of junk:

which is JB welded to a third piece of PVC pipe.
Also I'm using a condensor I bought from someone but it's the same one that the micro35 uses so far as I know.

I should have time in the next few days to take this thing apart so you can see exactly how it works. It's pretty simple. I also built a jib today so maybe I'll post some crazy jib/adapter shots tomorrow.
 
yea the highlights are Tight! it looks like we can make some nicely blown out, over exposed images and have it look ok, instead of a solid stream of evenly colored white.
