Extension tubes/rings are even less expensive than that, and less fiddly in my experience.

kbob, that looks really nice!

As someone who uses a DSLR as their primary camera, and is too cheap to get a macro lens, I usually just set up a few feet away on a tripod with a zoom lens, and really take my time getting the focus just right. You can get pretty good results. For example, this was taken from about four feet away.

That's an M6x1 thread, as a size reference.


I've heard of flipping around lenses, but have never done it. I'll put it on my list of things to try.

As I was a student I "modified" my father's SLR Camera with a coupler-ring and a DIY-tube. This was a cheap solution but useful.
Unfortunately now I'm missing the "D" for Digital. :)

Inspired by this video:

http://cnettv.cnet.com/diy-iphone-macro ... 31027.html

I experimented with my iPhone (3GS, 3.2 MP camera!)

and here is a sample:

Blueline distance = 4mm, layer height = 0.25mm

This isn't surely the final solution :!:

Extension tubes are fine too, yeah, except:
a) they increase the chances of you getting crap on your DSLR's sensor
b) you have to buy them or machine them.

Of course, reversing lens has a disadvantage of its own, besides fiddlyness: you need to have a spare lens (which is a bit of a chicken and egg problem - if you have one, you're likely to be a slight bit more enthusiastic about photography and then you're quite likely to already have a macro lens).

@kbob
Thanks for your feedback, I like the Canon DSLR + Macro Lens. Let's see.

@orcinus
Thanks for your comments. The Pentax Camera is almost 40 years old! It isn't my intention to use the coupler ring and tube with a new digital camera. It's only nostalgia.

My Canon 60D + Nikon AF Micro-Nikkor 200mm f/4D IF-ED, just sold the 60D and got a 5D Mark II. These pics are from about 8" away.

The depth of field really blows on most macro photos. Some people use some digital layering techniques to help. Those light field cameras can do some amazing depth of field on macro shots in the right conditions.

That micro nikkor lens is amazing. Soooo expensive, but amazing.
We used one in a lab I interned at for taking pictures of water droplets blowing by in high-velocity jets of air. We would set it up so the septh of field was tiny (about 80um), and then we could take little "slices" of the test chamber.

It's awesome for portraits too.

Yeah, it is pretty stinking expensive, though I got mine for a real good deal, about $600.

The shallow DOF is easily solvable, just use more light and step down the aperture. Though that really only works with photos, I took this video with the lens and had to keep it open to get enough light:
