Aetna Rokunar lens model number 527895?
Is there anyone that can give me some information on a lens that I have...The rim of the lens says Aetna Rokunar / 1:3.8 / 80-250mm /No.527895 /made in Japan...I have searched everywhere and can't seem to find anything on this lens...Any help pointing me in the right direction would be greatly appreciated.
I tried to attach pics but I guess Y Answers won't let me...I guess what I'm trying to find out is what year this lens would have been produced, whether it can be adapted to mount on canon EOS models and is it worth anything or should I just keep for a paperweight...Any info or links you can provide would be great and I'll work on trying to get some pics out...
Answer:
Detailed pics of the rear where it mounts to the camera will tell us the most.
It's an 80-250 f/3.8 lens.
Manual focus
the 527895 is just it's serial number. The license plate if you will but there's no database to look up what camera it attaches too.
Aetna Rokunar was a third party lens maker. They made lenses for other camera makes.

Answers doesn't allow html for anything but a link. Keeps down on the viruses I suppose. http://www.Flickr.com is part of Yahoo, so activating an account there is relatively painless.
But that lens probably won't mount to your EOS camera. It's just a guess but not many manual focus lenses were made for the EOS mount. There are exceptions of course, but that's just my guess.

According To Consumers, What Is The Best DSLR Camera?
Anybody that has recently been shopping for a high-quality camera to purchase, has read or heard the term "DSLR Camera". DSLR is an acronym that basically means Digital Single Lens Reflex. DSLR cameras use a special type of lens that mirrors light to the view finder. DSLR Cameras work in the following fashion: The shutter click will result in the mirror being placed inside, and the light will at that point travel straight to the sensor. From there light goes to the sensor and blocks out the VF.
Features, The good, The Bad, and The Bottom Line
We've given a small description detailing the 2 different kinds/types of DSLR cameras below. Keep in mind that some people have wavering definitions, so we kept things basic and to the point. These points are the standard that everyone agrees with. The interchangeable lens will be our first example. Its one of the more popular DSLR cameras. The latter allows the user to change the lens. Its a great feature because it gives photographers the choice of being able to change the angle for the pictures they are trying to take. Canon and Nikon both have DSLR cameras with interchangeable lenses, but according to consumer reviews, Canon has the best. There is one Canon EOS Rebel T3 Reviews that states that its the best DSLR camera for novices and experts alike. Theres also the fixed lens DSLR camera and as the name suggests, this camera gets its name from having a fixed lens. A cursory glance at any of the best DSLR camera reviews will no doubt unleash the following features:
This kind of DSLR camera utilizes more than one type of lens
Easily padded up by use of powerful external flashlights, custom lenses et al.
Multiple Hi-Res Lenses
Good and Bad
One of the best things about DSLR cameras is the fact that they come packed with the most features, and you cant beat having an interchangeable lens. After reading the Best DSLR Camera Reviews, tests, and reports, we've gathered that some of the best dslr cameras use somewhere around the range of 25-30 different kinds of lens. That's a very high number! The 2nd valued feature dwells in the realm of resolution. Digital Single Lens Reflex cameras have a higher resolution than that of regular digital cameras, and most experts prefer to have this kind of quality. Its also good because not only do you get higher resolution, but that resolution comes coupled with the ability to use a wide variety of lenses. Thirdly, the camera has greater flexibility by way of the accessories that you can pad it up with, remote triggering devices, external flushes et al. Those features above is what you'll be able to expect if you ever plan to buy a DSLR. Those features plus MANY more.
If a bulky camera is a pet peeve for you, then welcome to your most hated camera, the DSLR. How are we defining bulkiness? By weight, size, and portability. The 2nd con that comes with digital single lens reflex cameras are the price. They can make a very substantial dent in your wallet if you don't know what to expect. Contrarily, when weighing in the benefits and rewards that come with these expensive, bulky cameras, you'll quickly understand why they cost what they do, and will be less bothered with the price. If your looking for something less complex/complicated, then chances are a point and shoot camera might be the best option. The changing of lenses during shoots, the expanse of buttons that one has to possibly master, in fact the entire gamut requires a rather steady hand to guide this ship and this could have the possible effect of intimidating many a user of these devices.
