Converter Help Needed

**Wayne Brown** · September 17th, 2011

I bought my Canon 400mm lens and some times I need to get closer in and the problem is that the canon TC's don't work with the lens is there any other TC that would work with the lens.

I had the same problem when I was using Canon, and there was one out there that worked very well, but I don't know if they make it any longer and I cannot seem to think of the name of it now. But it did auto focus very well when use, but you need good lighting.

Will Kenko not make one? They make them for most fittings and the 2x that I have for my Nikon 300mm is very good when used on a tripod

Yes they do make one, as I was looking into this and the one that might work is the DGX model, from what I found this will report the lens settings propery in the EXIF data. They other one thast does not seem to do this well is the Tamron.

Wayne,

You need to Google these both and make sure that you will be able to auto focus with either check out the reviews from others as well.

Thanks Guys for the advice on this. I will google it and make sure that I read all the reviews and as you pointed out to make sure that they will AF with the lens to bad that canon TC will not AF would make it better.

Wayne I noticed that you are from Sarnia, which means that you might have a hard time getting the converter here and may need to go to the USA for it? I have not checked any Canadian sites for this so someting that you might want to do.

Thanks, I did a search on the stores in Canada and they don't carry all the brands but some, but more selections in the states. Still looking at some reviews to see what works with AF

Does any here use third party TC converters?

I did some searching and some say that it may auto focus and no guarantee. Was doing some reading and some say tape the 3 pins down and others report that it works with out the tape man this is not going to be easy.
I want to order ths converter next week. It would be cool if I can find some one that has done this.

Wayne this is common practice to get the converters to work by taping the pins. Now you might get away with it with out the tape, and I know that the Tamron converter I had worked with ou the tape and in fact it worked very well and reported the f/stops fine. I think that the tape helps in correcting the right f/stop used for the camera. I would suggest before you buy the converter that you do a search for your camera and lens and third party converters and see if there is one that will work with out taping the pins, I'm not a fan of doing this sort of thing.
