RED SPIDER MITES LOVE THE D60 !!!

Bet you've never seen one of these critters.
They are about 0.5mm long.

It took all 3 extension tubes + the 2x TC on top of the incredible 28-135 IS to
get these shots.
Not my best macro work, but it does push me a little closer toward the 65mm
MP-E lens.

Kibo informs me that (Annika1980) stated that:

You should try it again with a prime lens instead of a zoom.

 

I'll offer a lend of the feckin fantastic 135 f/2.0 L

 

Crappy actually.

That lens seems very specialized and might end up on the shelf unless
you do a lot of very close up magnified macro work. You would likely do
better with an ordinary 1:1 macro like the Cannon 100 f/2.8 macro or
Tamron 90 f/2.5 macro.

Common in dogs, cats, hedgehogs, raccoons and squirrels. Does that mean
the mighty Jewel has mange? Please say it ain't so...

 

The Canon 100 f/2.8 is a very fine lens, an I suspect it would indeed do
much better than the zoom with stacked extenders (which basically enlarge
the center lens aberrations as well).

Alternatively, Annika could try and use a standard lens in reverse, held in
front of another (moderate tele)lens. If it works and the reversed lens has
a large enough aperture (to avoid vignetting), one could try and find an
adapter ring that fits the filter threads of both lenses.

To illustrate, I just handheld an old FD 50mm f/1.4 in front of my G3 point
and shoot, and got this: http://www.xs4all.nl/~bvdwolf/temp/Strawberry.jpg
(cropped some vignetting and downsized to full screen). The heart of the
strawberry-to-be is approx. 3mm. A much larger sensor should be able to
improve on that. Using a tripod and smaller aperture could have improved the
result, but as an illustration it should be adequate.

Have you seen Franks site? ... http://www.beautifulbugs.com/ ... Most taken
with the MP-E, a MT-24EX and a D60 I believe

Using extension tubes, you won't get the magnification with a long lens that
you will with a shorter FL lens.
I forget the formula for determining macro size with extension tubes. Maybe
someone else knows it?

Thanks for the link. You just cost me a grand.

Depends on the parameters available, but Extension = f*M , where f=focal
length and M=magnification on sensor.
Part of the extension may be achieved by 'focusing closer than infinity', so
the tube length may be shortened by that distance.

For Macro photography, total depth of field = 2*c*I*(M+1) / M^2, where
c=circle of confusion, I=aperture and M=magnification on sensor.
Circle of confusion depends on a number of criteria (wavelength, sensor
size, output size, viewing distance) but, for the D60/10D sensor, 0.016 to
0.019 are acceptable numbers.

Or for a more expensive solution for EOS camera mount systems,

There may be others offering such a solution.

I think my circle of confusion just got bigger.

 

Bart,

Just curious. How were you able to get the 1.4 open all the way. I
thought that the FD series would not open full unless it was on
cameral or was reversed using the MA-55 adapter. I have been wanting
to reverse my 1.4 but can't find the adapter anywhere. Any alternative
solutions would be appreciated.

 

It (mine at least) is full open when off camera. Should you want to close
aperture, you'll need to push the small (2/3rd hidden) spring in the barrel
that locks the fastening ring in place (small screw driver or paperclip).

For the method I described (in front of other optics, as a diopter lens),
you don't want to close the aperture, as it reduces field of view by
vignetting. However, just using it in reverse by itself does require an
adapter if I correctly (and vaguely) recall.

I sold my FD 50mm macro lens, and have since acquired the EF 100mm f/2.8 II
lens, so I've not felt the need to look too hard for a reversal ring.
However, it does work fine on my P/S G3 (even hand held), so I might look
for, or have one custom made, to bridge the 55-58 male-male filter threads.

Hello

It is worth buying a Canon just for the lens.
It looks like a terrific lens. Really only usable at life size as it
would be difficult to get close to some subjects for larger
magnifications.
