Need diagram for old Vivitar teleconverter lens

Can anyone advise me as to where I can get an exploded diagram of a Vivitar 2X telelconverter? There are no numbers on this one but it is a Pentax style screw on, made in Japan.

Thanks,
Ray

    If I got what you intended to send, (just got an "X" in the diagram box, which took me to the generic diagram at FixYa), it was not as specific as I'd like but definitely of benefit. Thanks.

What is T Mount Telephoto Zoom Lens with 2x Teleconverter


The T-mount is a universal thread developed by Tamron which allows various adapters to couple a lens to a wide variety of camera brands. If a lens is listed as having a T-mount, it means that the lens can be coupled to your camera if you have a T-mount adapter for your camera.

A 2X teleconverter (often called a doubler) enables a lens of a specific to be doubled. For example, the lens referenced above actually is a 650-1300 lens but with the 2X teleconverter the focal length can be doubled to a maximum focal length of 2600.

I have an Opteka 600-1200 telephoto lens which I consider to be a decent lens for its very low price. I also have a doubler which came with my camera kit. That means I can increase the focal length of my lens to 2400 but I cannot imagine any reason to do so. At it's full zoom 1200mm focal length, this lens is very difficult to handle and must be used on a tripod with a remote shutter release.

It is extremely time consuming to focus and must be focused very accurately because it has almost no depth of field. At 1200 mm, the slightest breeze or vibration will cause the picture to go fuzzy from movement.

The lens is also large and does not fit conveniently in a camera bag so it rarely goes with me unless I know for sure that I will need it. It is not particularly good for sports action shots because the action will be over before you are ready to shoot the picture. With very bright light (such as the mid-day sun) and pre-planning and pre-focusing you might be able to get some interesting sports action shots. Say you're at an automobile race and you know a car will be coming into view at a certain spot, you can set up for that spot then trip the shutter when the car pops into view.

All that being said, I think this is a good lens to have in my bag without spending $10,000 plus for a really good lens of this size.

Will a quantaray AF LD 55-200mm lense work with a 2X teleconverter?


Well, this teleconverter would act as a magnifier to your lens. If you get a 2x teleconverter, it will double your zoom. so you'd then have a 110mm-400mm lens. The teleconverter is attached to your camera first, then the lens on to the converter. Make sure if you get a teleconverter that it's an autoteleconverter. Which means that it will allow you to still use autofocus. I would also make sure you get a name brand that has good glass because some converters will tint your images to a yellow ish haze that would require a whitebalance adjustment.

Blurry pictuers


First of all, tele-multipliers or tele-converters do not have the greatest optics in the world, and are usually fine for close up images but not much else. Secondly, they do restrict the amount of light coming into the camera which could interfere with the internal metering. Third, you have additional lens surfaces to get dirty. To fix the problem, start with the easy one, and clean all lens surfaces meticulously with a soft lint free cloth. If that doesn't fix it, try shooting non-moving objects in brightly lit areas. If you are still getting blurry pictures, try using the tele-converter on a close-up image within the focal length of the lens combination. If that doesn't work, give the teleconverter to someone you don't like and go buy a good quality 50-135mm zoom lens. Vivitar, Sigma, or other similar lenses are good quality and are very reasonably priced.

Can I use a Kenko Lens with a Nikon D60?


If it's an AF teleconverter you will be able to use it and get proper exposure from the camera, but it will not autofocus with the D60. The D60 requires AF-S lenses and teleconverters for autofocus.

Tele converter option for Tamron 28-75mm f2.8


This is a lens for Sony/Minolta cameras. It is not compatible with the Nikon D90. Hence a Teleconverter for Nikon will not work on this lens to mount it to a Nikon D90.
