Macro by any means necessary club

Received the Amscope microscope objective and RMS to M42 adapter. Seems to work well; it'll be quite a beast to tame in the field for single shot images. Microscope objectives are more often used for macro stacking, which I might get to some day, but for now it'll be single image shooting.

Here's what it looks like:



Here it is mounted on the simpler of the two bellows I've got:





Working distance is pretty tight:



The field of view at about 120mm of extension is 5.13X.

What can it do? Here are some quick tests to find out. Nothing special for the lighting, just self timer and whatever AV decided to give me.

First some manufactured objects. A canadian nickel. Not exactly mint condition.





Canadian $10 bill. Our paper money is no longer paper, but polymer, so you won't see any paper fibers.





A bus ticket. (I told you nothing special for subject matter! ;) )



The perforated edge of the opening on a box of facial tissues. You can see how smooth the glossy card stock surface is in contrast to the fibrous interior exposed in opening the box:



And now for some organic subjects. Our violet is my most commonly used first subject for new macro gear. These were taken using my Asahi Pentax M42 Auto Bellows at slightly greater extension than the above shots. Live view rather than OVF. Unlike the above shots, I'm using the KP's on-board flash with extender/diffuser. I'll have to break out a manual- capable auxiliary flash to provide more light for future shooting. DOF is veeeery shallow.














Overall, I'm pleased. It'll take some getting used to, and I'll probably opt for tubes rather than bellows if I take it out into the wilds for bug hunting. It will be a challenge! But for $20 Canadian (!)., I figure I couldn't go far wrong. To have a look at the work of someone who actually knows what there doing, check this out Robert O'Toole's Close-up Photography: $17 Plan 4x Objective ? Close-up Photography. He warns that there are similar looking objectives that do not perform as well. I think I got one of the good ones. Any shortfall in image quality you see in my examples above is more likely to be the result of my technique than any deficiencies in the optics. It is a demanding little lens, and I will have to up my game if I want to get the best out of it in single-shot use. I will post results here as I (I hope) progress and advance in my use of this little unit. I'm looking forward to the challenge!

On first seeing this bird the day before, I thought it was a tacky, poorly painted statue of a bald eagle, sitting beside a neighbour's garden. Then it moved, and I realized it was something completely different; a newly fledged Turkey Vulture!



It's been hanging around for a few days, though I haven't noticed any adults feeding it. I wonder if it fell out of the nest too soon. It can fly or hop up to the height of the porch at least, but the first day my wife and I saw it ,it didn't do much more than walk or hop, and a little unsteadily at that .



A tighter crop from a shot taken from the same distance as the one immediately above, using my 55-300. I didn't want to go any closer and risk disturbing the bird, or trespass on the neighbour's yard.



The neighbour on whose porch it's sitting in these shots has since erected obstacles on this porch wall. Didn't work. It was back this morning , though it was gone when we passed by later in the afternoon.

Not quite macro, but as close as I could get with my 55-300.

Lovely! Your macro flower shots are immediately recognizable, whatever lens you're using. Good eye; really neat.

The dragonfly shot is cool! I haven't really tried exploiting the "macro" abilities of my Tamron 55BB. This makes me want to try it out on smaller, closer subjects.

Pixel stomping! I love it!

Nice series. Interesting how many versions of an image can emerge from playing like this. Each one is different, each one is interesting. Fun stuff!

Yes. I usually stop reading right there. If there are sample photos, I'll lok at them; that's useful. But a review "right out of the box" isn't that helpful. Commendable enthusiasm, but marginal utility.

At the 10mm end it would probably be focusing inside the lens, but I have hopes that towards the 20mm end of the range, the laws of physics may deign to offer me a modicum of working distance.:)
