Re: Is Canon EF 75-300mm f/4-5.6 III too heavy for the EOS M100 ?

The Fotodiox is working great -good focus/good IS and very good photos.  That's all I can ask.

 

I can buy 5 of them for the cost of one Canon.  They are not cheaply built (maybe not as well as the Canon), it works very well, and I bet they outlast me (I am 77 years old).

 

Unlike a lens, it is not a very complicated mechanism and $200 is a price only a pro or a truely dedicated amateur can stomach.  Photography is just one of the many hobbies I enjoy, so I think I made the correct choice.

 

I did go with a decent Canon lens, because I can see a bad photo immediately.


When I bought my M3, the adapter was $50.

I would guess it is OK. I doubt it will damage anything no matter how you hold it. The Canon EF 75-300mm f/4-5.6 III Lens is a plastic wonder and weighs in at a pound or so.  That shouldn't be any sort of a problem. Your  EF-M 18-55mm f/3.5-5.6 IS STM Lens is about 1/2 pound. And if you happen to have the Canon EF-M 18-150mm f/3.5-6.3 IS STM Lens it is 3/4 of a pound or so.


The lens doesn't have to damage anything in order to cause a problem. All it has to do is temporarily deflect the top of the lens mount relative to its bottom enough to make the focus points different at the top and bottom of the image. Easily correctible if the 75-300 were a tilt/shift lens. But it isn't.

And neither of us actually think that will happen, do we?  Let's face it, you can damage anything if you don't handle it correctly.

The 75-300 is about a pound. Some of the ef-m lenses come in at half pound.  Not enough to make a big difference.

Now if you wanted to put my big Siggy on it, yeah, the mount probably wouldn't survive.

EOS 1DX and 1D Mk IV, even less and less other stuff.
