Lensmate Sigma DP2/DP1 Adapter 52mm
price: $22.95
The Lensmate DP2/DP1 lens adapter features a 52m filter thread which provides a much greater selection of filter options than the OEM 46mm thread.
Additionally, the larger size allows the stacking of filters and hoods with less likelihood of vignetting. Each is precisely machined from solid Delrin™ rod, checked for fit, then laser engraved. Besides protecting the lens, the adapter improves handling by providing a secure place to grip the camera.
Sigma DP2 and DP1 FAQ
- Does the adapter itself create a flash shadow?
At the wide zoom setting, the adapters will cast a shadow when using the onboard flash. The shadow gradually diminishes and disappears as you zoom toward telephoto. It only takes a second to remove the adapter for a flash shot. For best flash results when using the adapter with a conversion lens, a hotshoe mounted flash is recommended.
- How do I attach the Lensmate adapter to the Sigma DP2/DP1?
To attach, remove OEM lenscap. Place adapter over bayonet mount and twist clockwise until it locks.
- I find it difficult to thread the converter onto the adapter, what am I doing wrong?
You'll find that it's much easier to thread the converter onto the adapter before mounting the assembly onto the camera. It's also a good idea to turn the camera off so the lens retracts before attaching the adapter to avoid the possibility of damaging the zoom lens. If you have more than one converter, you might want to get an adapter for each so they'll always be ready to bayonet onto the camera quickly.
- Will adding any kind of compatable conversion lens affect the DP2/DP1s auto focus?
No because the LCD shows exactly what the camera is seeing with or without the conversion lens.
- Why do I need a polarizer? do I need a linear or a circular polarizer?
A polarizer deepens blue skies and takes the glare off water and glass. For an excellent comparison see below. You can use either a linear or a circular polarizer with the LX3/DLUX4. We sell the circular polarizer because it is available in a HMC multicoated filter where the linear polarizer is only available in black in a double coated.
Place your cursor over the image to see what it looks like when a polarizer is used. The two images were taken a few seconds apart, no post processing.
- What is the difference between a double coated filter and a HMC?
HMC means multi-coated or six layers of a coating (three per side). The HMC multi-coat greatly reduces flares when shooting into the sun or when the sun strikes the filter compared to the double coated (single coating per side).

DP1 and Infrared
When I found myself with an extra DP1, it occurred to me that it might just make a dandy infrared camera. So against my better judgement, I immediately proceeded to disassemble it to remove its IR block filter. The most difficult part of the process is actually removing that filter since it's attached with adhesive film to the sensor mounting plate and mask. So it needs to be carefully excised without damaging the mask. No doubt someone will be offering this conversion so you won't have to do it yourself. Of course with an external filter, there's the possibility of using one camera for both visible and IR photography with the appropriate IR block filter.
The DP1 focuses perfectly even without the IR block filter, though AF is hit or miss - I just leave it at infinity MF and focus is excellent, even at f4 or with a wide conversion lens. Image quality is excellent, and with an R72 filter (haven't tested other filters yet) there's no dreaded hot spot at any aperture.
Dynamic range is just as impressive in IR as it is in visible light, and negative fill light judiciously applied in SPP creates a halation effect not unlike HIE film. There isn't room inside the camera for an internal filter (not where the IR block filter was anyway - it's only about .018" thick). I use an R72 filter either on the lens adapter, or one that fits inside the Nikon WC-E75 .75x.
