A Macro Safari

Yesterday was a rainy, hazy day at home.  I didn’t feel much like going anywhere but I needed to find something to do that didn’t involve sitting or work.  I decided to break out one of my macro lenses and a flash with soft box diffuser to go macro hunting around the house.  The random breaks in the rain would give me a few minutes at a time to venture beyond the front door to explore all the plants we have around the house.  This macro safari managed to keep me entertained for the afternoon and on into the evening.  I started out photographing some flowers but soon found some other more interesting subjects.

I chose for this residential adventure the versatile, amazingly capable AF Minolta 100mm Macro f/2.8 coupled to a Sony A7RII via a dumb (no communication with the camera) metal adapter.  This lens is capable of reaching 1:1 reproduction without an extension tube.  I picked this lens up from a local camera shop a few years ago for a swell, used price of around $250.  Considering the fact that it’s the same optical design as the modern Sony 100mm macro (Sony now owns Minolta), it’s a no brainer.  Why spend many hundreds more just for a Sony badge?  This old Minolta mated to one of the most advanced, high resolution cameras on the market shows just how good it still is.  You’d be hard-pressed to find anything modern, at any price, that can outperform it.

Coming up are some photos made with this lens.  Flowers and insects abound in Florida!

A Tequila Sunrise Hibiscus flower.

Here is a 1:1 macro of this same flower’s stigma (red bit) and anther (yellow stuff).

Another 1:1 shot, this time of the tiny white flowers nestled between the pink, papery leaves of a Bougainvillea vine.

I have no idea what kind of flowers these are.  Each is about 1″ in diameter and sits in a hanging basket alongside some other pretty stuff.

A striking portrait of the new flowers on one of the Crepe Myrtle trees that line the driveway.  Using a fast shutter speed and a tiny aperture of f/32, all ambient light was cutout, leaving only the flowers exposed by the closely positioned flash mounted in a 12″x12″ soft box.  I like this shot because it includes all phases of growth:  new buds, opening buds, open buds and then the full flowers.

I spotted this teeny tiny Long Legged Fly (Dolichopus Condylostylus comatus) resting on a frond of a palm tree; it’s about 1/2 the size of the common house fly but at 1:1 reproduction, you can really get in close to see all the interesting details.  To me, it looks like some kind of alien flying machine.

After about half-an-hour of not finding anything else to shoot, I went inside to call it a day.  That’s when my wife spotted a Florida Scorpion (Centruroides hentzi).  These little guys are very common around here.  They’re only about 1.5″ long, head-to-tail, and pack a very non-threatening venom that causes about the same sort of short-term discomfort as a bee sting.  Up close, I think they look like land lobsters.  I’m not a fan of eating bug meat from the sea so this doesn’t bother my appetite any.  After catching this little guy, I placed him on a piece of old, weathered Live Oak I staged on the dinner table.  The scorpion was quite happy to remain on its perch no matter how many times I repositioned it or nuked it with the flash.

I had some closer shots but I preferred these images that showed the whole body.  What an interesting critter!  The scorpion never attempted to strike at me, preferring to lie flat and still, hoping I would just go away.  When I was finished shooting these photos, I took the little guy outside and let him loose in a mound of pine needles at the base of a tree.  I don’t mind having these around since they help control the population of other, ickier insects.

What a fascinating way to spend an afternoon!  A good macro lens can have an enlarging effect on your sense of the world around you.  Your neighbors will probably think you’ve lost your mind as you become more and more obsessed with crawling around in the dirt and rummaging through your planters looking for new things to get up-close with but it’s worth it.  Even the tiniest of yards will provide an endless supply of subjects if you’re willing to look hard enough.

If you aren’t already kitted out for macro photography, it doesn’t have to cost a ton of money.  A simple extension tube set can cost less than $20 and will allow you to mount a lens you already own to get down into 1:2 or even 1:1 reproduction ratios.  A cheap manual flash and a sheet of white paper is about all you need for lighting.  There are plenty of websites out there with suggestions and reviews for this sort of thing.  The world of Macro Photography promises to challenge you in new ways while showing you how much detail there is in nature that we often take for granted.

 

Update:  In response to the questions I’ve received in comments and email, I’ve added some additional information and photos of the exact lens I used to make the photos in this post.

The lens:  Minolta Maxxum AF Macro 100mm f/2.8 (1st Generation, 1986-1993)  The aperture can be stopped down to f/32.

This is a Minolta A-mount lens.  You could use an expensive, active adapter (LA-EA3 or 4) to gain auto-focus but for macro there really is no need for this.  You set your focus to minimum distance (1:1 reproduction) and just move the camera closer or further away from the subject.  Aperture control would also be gained by that kind of adapter but for macro you’re going to be stopped down fully if not very close to that in order to get enough depth of field.

The adapter I use is a perfectly fine and an inexpensive ($15) one made by Fotasy.  It is a Sony A-mount to E-mount dumb, metal adapter that features a manual ring which controls the lens’ aperture.  This is required due to the lens not having an aperture control ring of its own (normally electronically controlled by an A-mount camera body).  You’ll see in the photo above that the adapter has a ring with the label, “LOCK <—> OPEN”.  Turning this gives you step-less control of the aperture and no indication of what aperture you actually have set.  To me, this doesn’t matter with the Sony mirrorless on which this adapter is intended to be used.  I can see in the viewfinder the effect of any change.  If, for some reason, I need to know exactly what aperture I’m at, I could derive this by counting the stops on the exposure meter as I close down from wide-open.

How I use this lens and adapter:  I set my shutter to max sync speed of the flash, set aperture to whatever I need (typically stopped all the way down to f/32), and hard set ISO to 100.  Then, I control power output from the flash to nail down my exposure.  I used a Cactus flash with 12″x12″ soft box and found I was between 1/16th – 1/2 power for most things.  Once a flash power is found to work at a particular distance, I don’t need to really fiddle with it.  I error on the side of underexposing to protect all colors from blowing out.  The RGB histogram can be particularly handy for checking on this, especially when it comes to the intense colors seen in flowers.  You can totally blow out a single color channel and still not see all-white in the image review.  Blowing out even a single color (Red, Green, or Blue) will mean loss of fine details and color transitions in a vibrant flower.  You’ll see vibrant colors but it’ll be muddy and featureless.

Here is a photo of the Minolta mounted to an A7RII with battery grip.  A very reasonably sized package for handheld macro work!

I hope this extra information about the lens and how I use it will be of some use to those of you who expressed an interest.  If you have any further questions, don’t hesitate to ask.

  1. Wow, really interesting work, macro photography just has a certain crispness that I just find beautiful, great shots by the way.

  2. Wow, I had no idea that Minolta AF lenses could be used with a dumb adapter. Apparently there are a few different versions of the 100/2.8, mind if I ask which one yours is?

    The 5th pic from the top is especially nice (white flower on black).

  3. Hi aprilius20, to better respond to all the inquiries, I’ve updated the original post with a bunch of additional information about the lens, the adapter, and how I use it. Do please have a look at it to see if I’ve answered your question. The short answer to your question: I have the 1st Generation version built from 1986-1993.

  4. Thanks for the detailed explanation!
    Very thoughtful of you to show the entire setup too.
    Good to see that it’s not that large a combo…
    It looks shorter than my MD 100/4 (with 1:1 adapter), and being a few stops faster…
    Time to add yet another Minolta to my wish/shopping list. 🙂
