How cool is this?

When I was using the earlier Sony A7 cameras for insect macrophotography it was always a struggle to manage to get good focus on active insects like butterflies and bees. When magnified view appeared in the A7S (and elsewhere) I started using that to get really close focus on the heads of bees and other small critters. But the challenge was to perform the magnification button clicks and focusing before the little buggers moved on. And another complication is that only single auto-focus and manual focus work with magnified view, not continuous auto-focus.
So recently I decided to try using continuous auto-focus instead of magnified view with the active insects. And I’m satisfied that, all things considered, this is the better technique. Probably those coming from camera models with a longer history than Sony of competent auto-focus are not surprised by my finding. After all, continuous auto-focus isn’t a new technology. But it is to me. Having competent auto-focus on a Sony A7 camera is a relatively recent phenomenon.
What I think are the big advantages of this technique are really just the lack of the disadvantages that the magnified method has. With the continuous autofocus method there is no rush to try to restart the magnified view after every capture. This alone is worth a lot. Between continuous auto-focus and multiple shooting modes I can take a dozen shots in the three or four seconds it takes to get two shots using magnified view. And sometimes that is all the chance there is to get the shot. Looking at the results confirms that the number of keepers is much higher. Not to mention how much lower the annoyance and frustration levels are when shooting this way. It makes it easier to keep a handle on the environment and react to the movements of the insects faster. And this should be obvious. When in magnified view there’s no way to find the bug when it flies to a new location. You’re force to take the camera off your eye to find the insect again. Often, you’ll have to back it out of magnified view and start over once you relocate the target.
So, here’s my restating of the obvious but if it helps anyone else out there in Sony camera world then good.
I don’t take many photos of bumble bees because they are so ubiquitous around my yard. So I don’t pay them much attention. BORING!
But one time I noticed a bumble bee on a flower that seemed interesting. He was sitting on a flower and not collecting pollen. So I took a closer look.
And what do you know, it’s a robber fly. Notice the enormous bulbous eyes that protrude above the head. Look at the long coarse hairs around the mouth and the thick piercing organ sticking out. Notice the clear separation between the head and thorax.. Finally notice that the back legs lack any pollen baskets that a real bee possesses.
Here’s a blurry closeup of its head and thorax.
I remember reading in a book on close-up photography the author’s respect for the ferocity of robber flies. He said something like “if robber flies were the size of dogs we would be afraid to ever leave our houses for fear of being eaten alive. Sounds like a good premise for a science fiction story.
Robber flies come in various shapes and sizes and only a few are mimics of bumble bees. But they all are ferocious predators and mostly hunt by ambushing their prey.in flight. And if you are careless they’ll even give you a painful bite if you attempt to catch them by hand.
I’ve found several different types of the robber flies on my property and I find them very interesting.
I was able to get a close look at this one by using the magnified view that my Sony A7 III provides. That means I didn’t have to get too close to see it. These things are very skittish and it flew away before I could get close enough to do a naked eye visual.
I have too many shots of this goofy beetle. So instead of stringing them out, here they are in all their chitonous, coleopteran tediousness.
