Here is a real dilemma.
Decided I needed another 49mm polarizer.
Bought one off e-bay, kinda felt like a bandit picking it up as the only bidder for $.99+ shipping. Came in the mail, opened it up to find a nice leather case, opened that to find 3 lenses. marked Pro 49mm (actually a 0 with a slash) +1 Japan. And a +2 and a +3. And a nice little paper chart Titled Coated Close-up Lens +1 +2 +3
The Bottom of the page has a Blerb....
Filt-up Lens
googled filt-up and it referenced telesor
So did I end up with a set of +1 +2 +3 close-up lenses made by telesor? who ever that was?
my apologies if I am in the wrong place to ask this question.  |

As long as they are clear and you can see the refraction of the lense they are close up lenses, a polarizer would be darker. They are graded in 1,2,3 that is the amount of magnification for each 1 being the lest and 3 higher. 99 cents is still a good price if you can use them. Don |

Telesor is or was a marketer of various relatively generic stuff, but often decent enough. If you're using an SLR, you can easily determine how useful they are by putting one or more on the end of a lens. Diopter lenses tend to distort a little more than an extension tube, but they have the advantage that they do not diminish the light, so they're useful when you need better light, or if you don't want to fuss with meter compensation. And of course, they're also very portable and compact. If you're shooting flowers or bugs, or other subjects that do not have straight lines, and don't go all the way to the frame edge, the distortion is not usually a problem. You can stack them too, to increase magnification. Try them. You may be pleasantly surprised.
A bargain at the price; the little leather case is probably worth a buck anyway! |
