All,
As some of you may recall, I've been messing around with making my 'own' lens. The original threads can be found here:
Lens - (there was a url link here which no longer exists)
Shutter - (there was a url link here which no longer exists)
So over the weekend, I took the temporarily assembled lens out for a test - to be sure it was what I wanted before I began cutting metal.
Here's the negs. Note however that when going ghetto, ghetto is all you can go.....My scanner doesn't play well with Linux, and I have yet to bother to purchase one that does (I had ordered a 4870...But after getting one that was DOA, I discovered that Epson isn't the best company in the customer service dept) . So....In a disgusting gesture, I have placed the negs on my light table, photographed them with my digicam (ca. 1999), and inverted them. Please don't judge such things as exposure and contrast, as its impossible to see. Also, be take notice of relative sharpness, not how sharp it looks on screen. One of these years I'll get a scanner and do it right.
f/3.8
f/5.6
f/11
f/22
In the other thread, I commented about how the distortion seems to be dependant upon bellow draw just as much as it does on the aperture. You can see what I mean by looking at the f/5.6 shot (closer than infinity), and then looking at the f/11 shot (infinity).
Thoughts ?
