I think it's the best way to go for you :-) They are adapter rings but try searching without the word 'rings' and you might get more choice. For example: Canon EF to C/Y adapters (not including EOS-M)

Canon EF is probably the most versatile mount to adapt to other mounts - C/Y and M42 are no problem but Canon FD won't work without using an adapter with optical correction to retain infinity ...

Ahh - I get where you're coming from a little more now! Having read a few of your posts in the past I'd sort of formed an impression of you constantly and fruitlessly searching for optical ...

An interesting approach but I'm wondering what purpose is served by it outside of academic research purposes, or maybe that is the point? I used to be an obsessive pixel peeper but, personally ...

If you get the FD mount version, you can get an FD to M42 adapter and use all your lenses. You cannot adapt from M42 to FD. You can use a focal reducer on a full frame camera but it will vignette ...

In Aperture Priority mode (A) the camera will meter the scene and (assuming you're not using Auto ISO) set a shutter speed which you can then adjust to your liking using exposure compensation if ...

That's annoying, but you can't really tell at this display size! Maybe you need some larger (or more) memory cards ;-) - assuming the only reason for the reduced res was to save space...

Well said

You've done a pretty good job at focusing on details with that shot :-)

It's a shame you've had problems sourcing a good Canon LTM 50/1.8 - I find it to be an excellent lens. I have a preference for silver lenses so have an early chrome version whereas I believe you ...

If it looks like a 2 (preset) then it can't be a 7; if it's not a preset then it can't be a 2; if it has an auto aperture, an a/m switch and 8 blades then it's probably an M ;-) Doesn't really ...

Lovely hint of sunshine breaking through! I'd leave it alone - the elements that should be vertical (fence, trees, houses etc) are straight and the landscape is sloping. No problem ;-)

I had to clean some elements on mine but it was some time ago so memory is a bit hazy... I do remember that the front group (including aperture mechanism I think) was very easy to separate from the ...

I would suspect the adapter is just a little bit too long. It's more likely than the lens being faulty assuming your lens is in good condition with no obvious damage. The vast majority of adapters ...

Small :-) On the relative behemoth that is the A7II, it would look even smaller. Even this is massive next to that Yashica T4  lens Mathieu18 has adapted, but this is much faster and has helicoid ...

It seems amazing that such a tiny pancake inc. helicoid can do that. Makes me wonder (again) why so many modern lenses have to be quite so bloated even bearing in mind all the corrective elements ...

A lovely atmospheric image. Great B&W conversion :-) In terms of IQ, looks like good detail across the frame. As you know, I'm tempted to get one of these to try and see if it covers FF. Failing ...

In my opinion, just choose the lens that's in the best condition for the most reasonable cost :-) On the Sony A7, there's no real disadvantage in using either mount - you will get the same result ...

Surprised nobody's mentioned the Tokina RMC/Vivitar 17mm f/3.5. Bit wider than you asked for but well within budget and really not a bad lens (stopped down a bit) if you find a good one. Nikon AI ...

Assume nothing on eBay. Many experienced sellers will specifically list faults (or lack of faults) and show good quality images of the actual lens. Try to only buy from sellers with 100% positive ...
