Can I change my aperture when using this lens mount adapter?
Yes, you can.
Because this lens mount adapter is electronic, most electronic lens functions – aperture, exposure, autofocus, AE metering and image stabilisation work as normal. This means you can use a Canon EF lens fully automatically with your Micro Four Thirds (M4/3) camera.
What is a lens mount adapter?
A lens adapter allows you to attach a different brand of lens to your camera body, letting you use an otherwise incompatible lens with your camera.
How do I find the right lens adapter for my lens and camera?
Find your lens mount and your camera mount.
The easiest way to find and confirm your lens mount is to know the mount of the camera it was used on originally. A quick internet search of the camera model followed by lens mount is a sure way to confirm what lens mount you need. For example if you have an old Nikon lens and you know it was used on a Nikon FM2, you can easily find that the lens has a Nikon F-mount. This is particularly useful for lenses that are made for different mounts i.e Sigma and Tamron bring out the same lens with different mounts including EF, F, E so knowing the camera the lens was used on is a good shortcut.
If you have an old second hand lens and you are unsure of the camera it was made for, take all the known details of the lens and search the web.
Why buy a lens mount adapter?
To utilise quality old lenses with your new camera, or match a different make of lens to your camera.
There are countless creative experiments to be explored by mixing different brands of lenses with your camera body. Lens adapters can also help your existing collection of lenses go further with any new cameras you collect. So you can invest in a new camera and make the most of your favourite lenses.
How do you use a lens mount adapter?
Find a detailed how to for each filter at the base of its product page.
In summary, attach your lens to the adapter, and then your adapter to your camera body. Put all settings on your lens and camera into manual mode, and select ‘shoot without lens’ in your camera settings.
When should I use a lens mount adapter?
Whenever you want to use a different make of lens with your camera body.
Because you need to use your camera in full manual mode, you may need to familiarise yourself with this before shooting. You’ll soon work out which lenses you enjoy using with your camera. Analogue lenses can provide professional quality glass at a fraction of the cost of modern lenses so lens adapters can help you shoot with better lenses for less.
So far looks like it will meet my requirements. Plan to use it in a couple of weeks to shoot the solar eclipse.
I’m pretty happy with this adapter- frankly ordered it because of the aesthetics of Urth!
I am using it with an Olympus OM mark ii mirrorless camera and wanted to take advantage of using my husbands canon EF lens. Since this was a sometimes use, I couldn’t justify the meta bones adapter for 700. I’m very happy with how this works but there is a bit of tweaking of settings to get it to function properly. Lens stabilization needs to be turned off (lens) and some minor tweaking of focus may be required; I’d say it gets you 95% of where you want to be focus wise and then you need to manually adjust.
