Interesting what One Finds Among the Forgotten

I'm getting ready to trade/sell some camera stuff I haven't used for a while -- in some cases -- not for years.

In a canvas bag with filters, a flash unit and some other accessories, I came across a Diopter +2 lens ; in jargon-speak, a diopter is

a unit of refractive power that is equal to the reciprocal of the focal length (in meters) of a given lens.

In plain English, a diopter lens works like a filter; it screws onto the front of a regular lens and modifies in some way, images taken with that lens. In this case, it allows the lens to get literally within inches of a subject and enables that lens to focus within inches of the subject. For that reason, generically it's referred to as a "close up" filter.

It looks like this.

'Course, I just had to try my old friend filter and after doing so, decided not to part ways with it. Here's one reason why not.

755_discussions.jpg This is actually slightly cropped for compositional purposes; it will still print razor sharp as an 8"x10" @ 300dpi -- pretty good enlargement when one considers the actual size of the depicted objects. That makes the lens a "macro" when the filters attached.

For the record MACRO PHOTOGRAPHY is

photography producing photographs of small items larger than life size.

Stay tuned, I'm just beginning to get reacquainted with my long lost filter; you might say, like old times, "we're again getting close".

Close relationship re-kindled.

It's interesting that the filter was able to fit your new lens. They vary so much in size and thread.

However, it did a magnificent job. The photo is exceptionally sharp. You probably had to get really close to that bee.

Buzz,

The lens slides into a bracket the diameter of which corresponds to the lens to which it is attached (screwed onto the thread). The brackets come in sizes (diameters).

In order to focus with the diopter on my 80-400mm lens, I had to get within 4-6 inches of the bee; using an external flash, I was able to use an aperture of f22 which put the bee and flower in good focus while keeping the background soft and blurred.

My idea of fun!

My mother gave away almost all of my father's photographic tools, including his Nikon with the hunga gunga lens. I'm really glad that you found yours, because old friends are sometimes the best-- if only because we're used to them...

Great picture, dear A. Mac! As always!!!

Really fine detail of the bee with that lens. Still, you had to get closer to that bee than I would have been comfortable with.

I may have some reservation regarding the Timber Rattlesnakes and Black Bears in the Poconos.

'Course, "getting the shot" tends to motivate me.

Is it just me or are columnist pieces no longer part of the FP sequence ?

Perhaps it is a manifestation of the "will of the people," Petey.

Ain't it grand when something you had forgotten about shows up?
