Now, I don't have a dslr I do have a camera with a barrel style lens 28-300 mm. Well I had a cool idea today, I am going to try to make my own lens, out of a cardboard tube and I really don't have much more in mind yet, what i'll use for glass etc. I'm thinking of going to the dollar store, thrift shop garage sales, etc. Buying old camera lenses, (cheap cheap) and cheap glasses and anything that has some magnification power, so you verdict? will it work?

It will be a fun project and I think you will learn an awful lot. My guess is that the dollars spent will be to gain an education rather than a very useful final product. Maybe plastic pipe instead of cardboard though...?

Its very strong cardboard the kind you ship posters in, and I already made one and it's not very good quality a lot of that is due to a couple scratches and such but there is a very neat effect, a little wide angle and a little magnification and a added blur all at the same time, I'll post some samples in a bit.

Its been done, cardboard lenses: http://www.photocritic.org/2005/macro-p ... -a-budget/ is a good example of a macro lens, but when i woke up this morning I wanted telephoto, like the nice 300-800mm sigma. Well after a trip to the dollar store I bought a really big magnifying glass and started messing around a bit. Grabbed my cardboard tube and cut it up taped my glass on and viola! I have some samples here (down below).

But first lets talk about it. It got a little scratched and dusty but what can you do? (not scratch it of course) I went outside anyway. the first few were less than spectacular but then I took a couple photos and my first thought was simply, "Tilt-shift" lenses like the lens baby.

The lens adds a little magnifications while simultaneously offering wider angle capabilities and a cool blurring effect even at f/8 (due to shape of the glass) So for 3 usd you to could have your very own diy dollar store magnifying wide angle tilt shift lens or DDSMWATSL, if you get some free time I really recommend making your own lens. I don't see this as practical but it is a neat effect. and I've been calling it a lens for me as I mentioned above, its more of an adapter, that goes on the lens so converter maybe being the right word?

and now, without further a-doo I present to you the Jake "A" Series (insert focal length here) wide-magni converter. (The a stands for affordable or maybe adorable)

First we have one of the first photos, a hatchet that i left out all winter to rust.

Next the two images that made me think tilt-shift:

and I really like the next 3, especially the 3rd one the bokeh isn't great not that smooth creamy but is a nice effect.

I'll have a picture or two of the lens(converter) in about 20 minutes

Wow nice job! It really "pulls" you into the shot. All future lenses like this should be called Jake Lenses. 8)
