Any teleconverters that work with Canon M series?

Maybe a stupid or easy question but I know in the EF line there are teleconverters that you can buy.

I am talking about teleconverters that go in-between the camera and the lens (not those that go at the end of the lens which are more aptly named as "tele conversion lenses" or "auxiliary lenses").

If they are could you help recommending me some for the Canon EOS M series?

In the past I have tested many auxiliary lenses and I enjoy testing them out seeing the difference. I now hope to try these "in-between" teleconverters instead.

Thank you!

Thank you appreciate this and any other recommendations for a "in-between" teleconverter for the Canon M series. Even if it means using a EF-EOS M adapter and adapting EF or EF-S lenses.

Jack, I've shot quite a bit with the EF 100-400ii + EF 1.4x iii TC (and adapter on the M6ii). It's definitely the king of the hill for the M System. I'd recommend starting there and then working your way down the food chain to get to what's affordable.

Large image. Click on "original size." The close-focusing ability of this combo is fantastic!

ps. The EF-S 55-250 + 1.5x TC "Larry Rexley Special" doesn't do too bad either (for a really cheap setup)...

2160 px image (uncropped). Good IQ if you don't need to go too big.

I'm just wondering, do these type of set ups require some "modification" or "do it yourself hacking" to get them to work or are they as simple as just putting the parts together and voila, they just work?

As in EOS M camera + EF-M to EF adapter + TC + EF lens?

Personally I've got a Canon M3, and I'm just looking for something that just works out of the box without modification

There is a Kenko HD DGX 1.4x TC for Canon Ef AND EF-S mount which may be not as good as the LR hack but I find it ok to use.

Just checked the price of this where I am at and it cost as much as a new lens.

Might have to drop the idea.

Not sure if you noticed, but you just linked to an old thread started by the same person who started this current thread.

In general, any teleconverter that works on a DSLR will work on the M system. The advantage of the M system with teleconverters is there are generally no limits on effective aperture. With DSLRs, some would disable AF if the effective aperture (TC + Lens) was slower than f/5.6 or f/8.

The "officially" supported Canon lens and Canon teleconverter combinations are any prime lens that is 135mm, or longer, as well as most of the TS-E lenses. For zooms, it is any zoom that is painted white. The 70-300mm L is on some official lists and not on others. This is because the teleconverter can only be mounted to the 70-300mm L when the lens is zoomed out to 280mm, or further. Canon lenses that are designed for teleconverter use all have recessed rear elements with large openings at the rear of the lens to make room for the extended front elements of the teleconverters.

Going beyond the "official" Canon combinations, there are numerous third party teleconverters. Some of these mimic the dimension of the Canon versions with extended front elements and others that have a recessed front element to fit any lens. Electronically, some of these third party lens will report their presence to the camera and display the correct effective aperture while others are wired straight through and are invisible to the camera. Third party options are too numerous to list and would need to be considered on a case by case basis.

Aside from some creative handiwork by Larry Rexley, there are no teleconverters available for EF-M mount lenses.

One last broad generalization... 1.4X teleconverters tend to have a minimal impact on image quality while 2X teleconverters tend to have major impacts on image quality.  In many cases, cropping and then upscaling a 1.4X image tends to look no worse than a 2X image.

Been meaning to update that thread, quite happy with that TC, but that is what I meant by "tele conversion lens" or "auxiliary lens", those go at the end of the lens.
This thread was more about knowing those teleconverters that go "in-between" the camera and the lens.

But seeing the prices of these "in-between" teleconverters, I don't think I will pursue it. I rather spend money on longer lenses like the 55-250mm STM or the Tamron 100-400mm or even the Sigma 150-600mm

Hahahah. Brilliant!

LOL, I thought that you had done this on purpose, which I thought was indeed brilliant!

If only it were so. I simply didn't realise it was another thread started by the same OP, largely because I'm an idiot.

I have actually use a picture owned by the same OP, when discussing something here with that OP, so not surprised it happens. I am sure this is quite common on DPreview because it's a small world after all.

Here's a shot I took today with the home-made 'Rexlar' 1.43x EOS M teleconverter I made, described in that thread.

Shot with the M200, EF-M 55-200 IS STM at 200mm: final focal length 286mm at f13, 1/400s at ISO 400. Image was cropped to 75% of original width, then downsized to 4k monitor resolution. A usable result, I think.

The rear of the train was more than a half mile away and quite distorted due to the 'heat shimmering' that hurt resolution in the more distant parts of the image.

Heritage 40-year anniversary Amtrak engine #130 at Tampa Union Station. Canon M200, Canon EF-M 55-200 IS STM lens, 'Rexlar' DIY 1.43x teleconverter, 286mm, f13, 1/400s, ISO 400, DxO PL5 cropped to 75% of frame width and downsampled to 2160 pixels high

Firstly I have to say it's an honour for "the" (the "the" here is pronounced as "d" as in D-Day) Larry Rexley to comment here.

I have to admit, I would one day love to try this method. Just waiting for someone to sell off his/her teleconverter on the low.

For the time being I have two tele conversion lenses (that go at the end of the lens) that I've been meaning to post up soon. I find it amazing that you can get these cheap nowadays (if you can find them that is), it's as if nobody wants them.
