Wrong X2 bought.

sukkie58 — Mon, 29 Aug 2016 16:34:19 GMT

Hi my husband has just bought me a X2, unfortunatly it's for L fit lens, I only have EF fitting lens, can anybody give me any ideas if I can buy anything to make it work. I have a 1200D. Thank you

What is a "X2"? What does it do? Who makes it?

Is it a teleconverter, to double the effective focal length of a your lens? If so, what lens are you trying to use with it? Depending upon the f/stop rating of the lens, it is likely that the AF, auto focus, system will not work with it.

"X2" and "L" make no sense in this context. Please give us exact model numbers. I certainly hope that "X2" does not refer to Fuji!

I think she means that she has a 2X teleconverter, which does, I believe, work only (or at least mostly) with a compatible subset of the "L" group of lenses. I doubt there is anything she can do to "make it work', but maybe she could trade it for a 1.4X TC, which may be a bit more forgiving.

But we really don't know. Since all "L" lenses are "EF Fitting" lenses.

I'm just as confused as others...are you talking about a 2X teleconverter? If so, is it made by Canon?

If it is, there are extrusion on the teleconverter that prevents it to fit with a number of lenses. These are the lenses that will fit:

EF 135mm f/2L USM
EF 180mm f/3.5L Macro USM
EF 200mm f/1.8L USM
EF 200mm f/2L IS USM
EF 200mm f/2.8L II USM
EF 300mm f/2.8L IS USM
EF 300mm f/4L IS USM
EF 400mm f/2.8L IS USM
EF 400mm f/4L DO IS USM
EF 400mm f/5.6L USM
EF 500mm f/4L IS USM
EF 600mm f/4L IS USM
EF 800mm f/5.6L IS USM
EF 1200mm f/5.6L USM
EF 70-200mm f/2.8L USM
EF 70-200mm f/2.8L IS USM
EF 70-200mm f/2.8L IS II USM
EF 70-200mm f/4L USM
EF 70-200mm f/4L IS USM
EF 100-400mm f/4.5-5.6L IS USM

Interestingly enough, they all happen to be L lenses but there are plenty of L lenses that won't fit either.

One temporary solution is to use it with an extension tube in between the two to handle the protrusion. This however, will prevent you from focusing to infinity because of the extension tube.

Thank you yes it is a teleconverter. So its no use to me as I only have EF lenes. Thank you.

You really don't want any help, do you?

Please tell us the model number of the Teleconverter.

Please tell us which EF lenses you have.

We are talking about EF lenses here and nothing else so it's not that "I only have EF lenses" but it should be "I only have the incompatible EF lenses".

Not sure if you know what's an Extension Tube is. It is a hollow tube that can be used to shorten the minimum focus distance of a lens - allowing you to get closer to the objects so you can better take close-up pictures. If you want to use the 2X teleconverter with your incompatible EF lenses, you can use the extension tube in between your 2X and your lens so it will physically fit.

The catch is you need to purchase an extension tube and you will not be able to focus on objects that are far away which probably defeats the purpose of the 2X converter.

Cheers all.

Its a canon 2x extender mark ii that he has bought, which fits the L lens, for which my hubby didnt know as he isnt into photography,

To save any more confusion here I have now bought an L lens to fit onto the extender.

Cheers again.

An effective, though expensive solution!

If you can get a full refund on the extender, get it. It's outdated by a few years. The main issue with it is that AF may not work on many lenses, and you will be forced to use MF.

Focal length multipliers (such as a 2x Extender) not only mutliply the focal length of the lens, they also multiply the focal ratio of the lens. In other words, your camera may no longer be able to use auto-focus with a 2x extender (depending on the lens.)

2x extenders should typically only be used with f/2.8 or lower focal ratio lenses because f/2.8 x 2x = 5.6 and any camera body can still auto-focus at f/5.6. However... suppose you have an f/4 lens and use a 2x extender... it now becomes f/8. Very few cameras (and only the high-end models) are capable of achieving auto-focus at f/8. This has to do with how phase-detect focus systems work.

You will also notice that the images aren't quite as sharp with the 2x extender as they are with no extender. There is a slight degradation of the optics.

This is typical and every tele-extender has this issue ... to some degree.
