Frequently Asked Questions

Can I change my aperture when using this lens mount adapter?

Only if your lens has a manual aperture control ring.

If you use a lens with electronic aperture and no manual control ring, because this lens mount adapter is fully manual, your aperture would remain at its maximum aperture (lowest f-stop).

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.

Quick Shipping and High Quality Product

Product shipped quicker than expected with free shipping as well!

The adapter is made well and fits tightly preventing the lens from wiggling at all. Having not much experience with lens adapters, I thought that I had gotten the wrong adapter (I have already gotten a wrong one before due to a error in the listing for the lens I got), but as it turns out, it was because the adapter was built just perfectly.

This was my first time buying from URTH and I must say I'm very impressed. I highly recommend this to anybody needing a lens adapter.

Excellent Accesory

An extremely well made adapter at a very reasonable cost. Works very well on my LUMIX camera with a selection of Pentax prime lenses. Very impressed as usual with the standard of Urth equipment.

I love this tiny piece of equipment

I recently switched from Pentax to LUMIX but have a few Pentax lenses that I fell in love with. Especially the fa 50mm f1.4. I can now use it on my gx80 and it is absolutely stunning. As long as your lens has an aperture- as well as a focus ring you are golden with this adapter.

Manual handling is no trouble at all with focus peaking and magnification.

In short, with just 23€ my lens collection for MFT has increased significantly in quantity and quality. Thank you Gobe(Urth)

Package arrived today

An odd one, this, supposedly a genuine Carl Zeiss Jena zoom lens. After ordering it from 'Urth', I did a bit more on-line research and found that it was highly unlikely that it was of Zeiss manufacture.

Evidently, it seems some Japanese firm had used the name. The lens looks to be well-made, but for some reason the retractable locking-pin will not lock the adaptor into position. Furthermore, as on commentator pointed out, Zeiss to the best of his knowledge did not produce Zoom lenses, only 'Primes'. To this day they produce mainly primes for manual focussing only. I have set the lens aside (it was supposedly in a Pentax fitting, and I shall keep my eye out for another 'Pentax

K fitting lens. as they are not all that rare. As far as the quality of the adaptor is concerned - excellent.
