Telephoto 48mm Tetraprism LensUpdated 20 days ago

Slide your iPhone into the included SANDMARC case — sleek, matte black, and ultra-slim with a soft rubberized texture for grip. Press firmly at each corner until it clicks into place. Make sure your case matches your exact iPhone model, as each one is precision-cut to fit.

Take off the front and rear protective caps before mounting. Store them in the included lens pouch when not in use — and if you ever forget your cleaning cloth, that pouch doubles as a great lens wipe.

Pair the 48mm with the free SANDMARC app, designed specifically for our lens ecosystem. Full manual control over focus, exposure, and shutter speed. Select your lens directly in the app and start shooting.

Locate the telephoto camera — the center lens in your iPhone's rear cluster. Hold the 48mm over the telephoto opening on the case, carefully align the threading, then twist clockwise with a couple of smooth turns. The aluminum threading is built for repeated use, so you can attach and remove it often without wear.

Open the SANDMARC Camera app, select the 48mm from the lens menu, and set zoom to 4× (or 5× on iPhone 16 Pro / 15 Pro Max models) to activate the telephoto sensor. From there, use the app's manual controls to dial in your focus, exposure, and shutter speed.

The SANDMARC case features aluminum threading that matches the lens barrel precisely. Secure, stable, and built to handle frequent attachment and removal without wearing down.

Screw the lens into the clip mount, then slide it over your iPhone's telephoto camera. No case needed — ideal when you want to move fast and keep it minimal.

Threads onto the front of the 48mm, opening up SANDMARC's full filter lineup — ND, Polarizer, Diffusion, and more for extra creative control.

Set zoom to 5× (or 4× on iPhone 17 Pro) before composing. This locks you onto the telephoto sensor the 48mm is built for.

The 48mm adds genuine optical reach — no pixelation, no distortion. Your images stay crisp at full zoom, unlike cropping in post or using digital zoom.

The 48mm produces natural background blur through optical compression. No Portrait Mode needed — subject separation happens organically at this focal length.

Even at 2× added magnification, minor movement gets amplified. Use both hands, brace your elbows, or mount to a tripod for the sharpest results.

Autofocus can drift at telephoto distances. Tap your subject on screen to lock focus and exposure before you shoot.

Wipe the front element with the included lens pouch before shooting. The multi-coating reduces flare, but a clean surface ensures maximum contrast and sharpness.
