Some customers have reported issues with Fotodiox brand adapter rings. For this reason, we recommend
avoiding these adapter rings.
If you're unsure if your lens is compatible, please send us a link to the technical specs of the lens at
[email protected] and we will do our best to find out for you.
Maintenance
The DOF MK2 is mostly maintenance-free. The sensitive focusing screen is fully enclosed for protection from
dust and damages. Due to the nature of this technology, there may still be microscopic imperfections or specs
on the diffuser surface of the focusing screen - which is normal.
ATTENTION: Disassembling the DOF MK2 will void the warranty and likely damage the internal optical
components.
Limitations
The DOF Adapter MK2 is an amazing tool for creating unique and artistic film-style looks, but there are some
limitations worth mentioning:
The image is flipped upside down
- as we mentioned in the recommended apps section, the DOF
Adapter MK2 flips your image upside down. Visit the recommended apps section above for more
information on third-party apps that correct this for you.
Edges of the focusing screen
- On phones with a focal length equivalent of 28mm or wider, you will need
to zoom in slightly to remove the edges of the focusing screen and fill the frame.
Light reduction
- the DOF Adapter MK2 reduces light by around 20%. You’ll also want to take your lens' f-
stop value into consideration, which also reduces light. For the best results, we recommend shooting in
well-lit environments. Visible textures - the focusing screen has microscopic indentations that diffuse light
and micro engravings on the other side (Fresnel lens), which are both necessary for the adapter to function.
In some cases you may see some of these textures in your image. These textures are more apparent in
certain lighting conditions and with smaller apertures (larger f numbers). For the best results, we
recommend using fast lenses, shooting in well-lit environments and always keeping your aperture wide
open.
Dust/Microscopic particles
- the DOF Adapter MK2 works differently than other optical systems. Since it
projects the image onto a small focusing screen, which your phone then records by looking through a
macro lens, it's very important to keep the focusing screen dust-free to prevent imperfections from getting
on your image. For this reason, we assemble the DOF Adapter MK2 in a clean, dust-free room and enclose
it on both sides with multi-coated glass to eliminate the chance of dust from getting on the focusing screen.
However, there's a slight chance that a microscopic-sized imperfection/particle/piece of dust that's naked to
the human eye could get on the screen during the manufacturing process and show up on your image.
