Telephoto 10x LensUpdated 3 months ago

The 10× Lens threads into the precision aluminium mount on a SANDMARC case. This is the only mounting option — no clip mount is included or compatible. At 310g, the lens is too heavy for a clip to hold securely. Cases are sold separately.

A tripod is essential for usable results at 10×. At a 10° field of view, the slightest movement throws the subject out of frame entirely. Use the SANDMARC Tripod or any tripod with a compatible phone mount. For combined zoom beyond 10×, a tripod is mandatory.

SANDMARC recommends keeping Camera at 1× or 2× for maximum optical quality — both use the main 48MP sensor. Combining with the iPhone's built-in telephoto camera gives more reach, but is best suited for subjects that absolutely require it, and always on a tripod.

At 240mm and a 10° field of view, the depth of field is extremely shallow — background and foreground blur quickly on either side of the focal plane. Always use the manual focus wheel rather than relying on autofocus. Small adjustments have a large effect; dial slowly and check the screen before shooting.

Tap and hold to lock focus and exposure, then fire with the volume button or a Bluetooth remote. Even a gentle tap on the screen at 10× will blur the shot on a tripod. Using a remote shutter eliminates the last source of vibration entirely.

At 240mm, backgrounds blur naturally and optically — not through software processing. This produces a smooth, accurate bokeh that digital zoom and portrait mode cannot replicate. Position your subject against a background with texture or depth, and let the optical compression do the work.

The included filter mount lets you attach SANDMARC's ND, CPL, Drama PL, and Scape ND filters. An ND filter is especially useful at 10× for slowing shutter speed in bright conditions — useful for smooth video panning shots or long-exposure landscapes at distance.

Multi-coated glass maximises light transmission and the lens performs in low-light conditions without the chromatic aberration or noise that iPhone's digital zoom produces at night. On a tripod with a longer exposure, the 10× Lens can capture city lights, stadium shots, and night landscapes at distance with excellent clarity.
