Freelensing the Pentax K-3II

Freelensing is a technique used with interchangeable lens cameras in both film-based and digital photography. The lens is detached from the camera and held in front of the lens mount by hand during exposure. This allows the lens to be tilted or shifted creating a similar effect to a perspective control or “Tilt-Shift” lens, only with a lower degree of fidelity. The result is a combination of selective focus and light leakage which are used creatively to create surreal imagery. Because of the increase in flange-focal distance, this technique is most successful with closeup or macro photography, where Infinity focus is not essential.

The lens used does not necessarily have to be native to the brand of camera, since it is not physically attached to it. In addition, the lens may also be reversed for Macro photography. By shooting through a normal to wide-angle lens backwards, increased magnification can be achieved. One of the by-products of freelensing is the introduction of “light leaks” which can be controlled to some degree and produce toy-camera like effects.

So yesterday (May 16th, 2017) I decided to try it. I grabbed my Pentax K-3II and my SMC Pentax-FA 50mm f:1.4 prime lens. I set the body to AV exposure mode & the lens aperture on manual wide-open at f:1.4 composed using Liveview.

This should only be attempted on a dry dust free location, unless sensor dust is wanted. I may explore this with my retired Pentax ✩istD body.

Going Buggy into Autumn

Today was the first day of Autumn, the thermometer was still hitting 27 degrees. Headed back to the Sunflower patch. Spotted another species of wasp, but it wouldn’t stay still long enough to photograph. Eventually colder mornings will slow many of these insects down. Once again I carried my aged Pentax ✩istD SMC-M 50mm f:4 Macro lens on Pentax T6-2X teleconverter, flash fill. This combination required me to be 2″ from the front of the lens to the subject.

These are very difficult as my macro lens only does 1:2 or half life size on the image plane. It’s also a f:4, so with the T6-2X Rear Converter mounted the effective maximum aperture is f:8. Lens was closed down to f:8-11 so works out to effectively f: 16-22, hand-held. Tripods are pretty much useless with small moving targets.

Went back today, Friday September 23, 2016. It was a more seasonal day weather wise. Lots of Bumblebees, honeybees, wasps, flies, ants and a few moths. I wasn’t able to get close enough to the small moths.

Going buggy!

It was another nice above seasonal, 25 degree late summer day in the Nation’s Capital. I popped my old manual focus SMC-Pentax-M 50mm f:4 macro lens onto my Pentax T6-2X to my aged Pentax ✩istD body.  All these photos required me to be 50mm from the lens front to the subject. Several skillsets are required, one is not to scare the insects away. And in the case of bees, wasps or hornets not to induce a defense reaction.

I went back today, another wonderful sunny day. The last day of summer, we were at 27 degrees today. I spotted my first Green Metallic Bee (gapostemon virescens). This small plot has 4 species of wasps, at least two types of Bumblebee, and as many other bees.

Stingers

Back to the Sunflower patch, breeze was lighter today, than yesterday. I was looking at stinging insects, the blooms were visited by Honeybees, Paper Wasps, mud Daupers and Bumblebees. First is a very abstract image.

IMGP0020Honeybee, Pentax ✩istD SMC-M 50mm f:4 Macro lens, flash fill.

I added my 2X teleconverter and was able to get more magnification on the busy little bee.

I also photographed 3 different species of wasps, first was the Black and yellow mud dauber (Sceliphron caementarium).

Next up is the European paper wasp (Polistes dominula), an introduced species.

I should look into replacing my well worn 50mm f:4 macro lens (1:2) with a 100mm f:2.8 version, as it will increase my working distance and will give me 1:1 or 2:1 with my 2X mounted.

Busy as a Bee

I was checking out the Sunflowers, and saw the Bumblebees hard at work. I mounted my old SMC Pentax-M 50mm f:4 Macro lens (1:2) lens.

I repeated the shoot the very next day, but I added my Pentax T6-2X Teleconverter to the kit giving me an equivalent to a 100mm f:8 (1:1) lens. I used some fill-flash .

One needs patience and luck because at macro ranges the slightest breeze moves the flowers and the bee wanders around. I really should update my Macro lens, as it’s an f:4 and is only a 1:2 macro. A 90 or 100mm f:2.8 would be more useful for this work.
