========================================

Why Use A Teleconverter?


A teleconverter is a magnifying glass attached between the primary lens and the camera body. It simply works by doubling the focal length of the primary lens attached to it, but it also cuts the maximum aperture in half. It is best to use teleconverters with telephotos lenses (eg. 90mm or longer, but best from 300-500mm).

It was basically the cheapest way for one to get in to super telephoto range, simply by doubling the focal length of the telephoto lens you already have, instead of having to buy a new and expensive lens. If you're a casual shooter, a teleconverter is nice. But you might want to invest in more expensive lenses with those low dispersion glass so you can also get a brighter aperture.

Modern day teleconverters are made specifically for digital cameras with their special coating, and they also support electronic lenses (eg. electronic diaphragm control and autofocusing). Vintage ones come from the era of film, and modern electronic lenses may not work with them.

Some of them are single coated or not even coated, then there are the high quality ones that have multicoated glass elements. If you look at the glass and see only one color (eg. amber, blue, white, clear) then it's likely single coated. Multicoated glass always show a variety of colors like forest green, cobalt blue, ultra violet, and maroon red.

You might also come across "matched teleconverters". How do they differ from "normal teleconverters"? Matched teleconverters are optimized for a specific focal range (eg. for 300mm only, for 500mm only). If you use other focal range, the image quality may not look as optimal.

Teleconverters come in 1.4x, 2x and 3x magnification. The focal length as well as maximum incoming light also doubles and halves respectively. That's why people generally use 1.4x and 2x. I have an upcoming 3x teleconverter in Konica AR mount (identical to Nikon F mount), which I bought specifically for macro use.

TIP: You need to use great lenses with this teleconverter to begin with. Otherwise, if you get poor results, it's not really the teleconverter. I've tried this on several lenses and there is no visible difference in quality with or without the teleconverter.

Unboxing Time!


I'm very grateful to come across this Kenko MC7 2x Tele Plus in mint condition, complete with mint looking box and papers, plus smelling like brand new leather!

The old Nikkor lenses are non-AI and have this rabbit ears attached to the aperture ring for metering. This specific teleconverter was made for the AI lenses, so non-AI cannot be mounted. I made a small compromise and bent the AI coupling pin a bit so that non-AI lenses can also be mounted.

This is a high quality 2x teleconverter with multicoated glass. You can tell by the greenish-purple sheen on the glass.

CONCLUSION


If you're very resourceful and patient, you will always find great stuff at the cost of only CHEAP. This Kenko MC7 2x Tele Plus is absolutely one of them and I was never disappointed even once. The 4 months of hunting for this was well worth it!

This Kenko MC7 2x Tele Plus often finds the Reflex-Nikkor C 500mm f/8 as its frequent companion in capturing monster sunsets and landscape scenes. But it also produces excellent macro results with my Tamron Adaptall 2 SP 90mm f/2.5 Macro (52B) which turns it into a 180mm 1:1 macro lens. With either lens, results have always been superb.

I tried it once with my Nikkor-S 50mm f/1.4 and set it to f/1.4 just to see how well it would perform on wide aperture, but the sharpness is still there and images appear with the same quality just the sameas if it were without the teleconverter.

This model was made for manual lenses so my electronic lenses cannot work with it. If I do mount them, there won't be any electronic aperture control or autofocusing. Kenko still makes them today and the new ones fully support electronic lenses.

This is a high quality teleconverter from Kenko, never failed me once! Have you tried one already? What are your thoughts? Write us a comment below.
