Sensor cleaners<br />

Sensor cleaning can be daunting, but there<br />

are plenty of products that’ll make it painless<br />

Y<br />

ou’d be forgiven<br />

for thinking that<br />

modern<br />

interchangeable lens<br />

cameras can keep dust<br />

at bay using their<br />

integrated sensor<br />

cleaning systems. But<br />

shoot in dusty environments<br />

or change lenses frequently<br />

and it’s only a matter of time<br />

before your sensor will need<br />

to be cleaned manually.<br />

You’ll know when to break<br />

out the cleaning products as<br />

images of clear blue skies or<br />

plain backdrops will begin to<br />

feature unwelcome dark<br />

spots, especially obvious at<br />

narrow apertures. But don’t<br />

despair, as with a steady hand<br />

and the right cleaning kit you<br />

can restore your sensor to its<br />

former glory. DSLRs are<br />

slightly trickier to clean than<br />

mirrorless cameras, as you’ll<br />

need to first lock the mirror<br />

up to access the sensor, and<br />

don’t forget to fully charge<br />

your camera’s battery<br />

beforehand. Then it’s just<br />

a matter of using a squeezy<br />

blower, brush, or a sticky pad<br />

to remove loose dust, while<br />

more stubborn dirt can be<br />

dislodged using swabs and<br />

cleaning solution.<br />

Of course it helps to have<br />

a decent view of what you’re<br />

doing, and though a good old<br />

head torch and magnifying<br />

glass will do the job, a<br />

cleaning kit with a dedicated<br />

LED magnification loupe will<br />

reveal even the smallest speck<br />

or stain.<br />

FIVE THINGS TO LOOK OUT For<br />

Keep these tips in mind and you’ll be able to banish that<br />

pesky dust from your sensor quickly, effectively and safely<br />

01 Wet or dry?<br />

If carefully used, specially designed swabs and solution will remove<br />

most gunk from your sensor, whilst a simple air blower puffs dust<br />

and debris away for a quick clean.<br />

02 The perfect view<br />

A kit with a magnifying loupe and light will really help you see where<br />

needs cleaning. Some ingenious designs also allow you to clean while<br />

the loupe rests on the lens mount.<br />

03 Plan ahead<br />

A basic blower will never run out of puff, but if you plump for a wet<br />

cleaning kit, the included swabs and solution will only go so far. Make<br />

sure replacements are readily available and don’t cost a fortune.<br />

04 Fit for purpose<br />

Camera sensors are delicate, so only use swabs and solution designed<br />

specifically for cleaning imaging sensors, not just optical glass.<br />

05 Less is more<br />

Squeezy blowers may be safe for a sensor, but don’t be tempted to up<br />

the ante with a compressed air canister. Their high pressure and<br />

freezing propellant can cause serious damage.<br />

LensPen<br />

SensorKlear<br />

Loupe Kit<br />

£50/$60<br />

www.lenspen.com<br />

LensPen proudly asserts that<br />

its cleaning equipment is used<br />

by NASA on the International<br />

Space Station. This kit includes<br />

a range of gadgets for<br />

performing a dry sensor clean.<br />

Identifying any dust is a cinch<br />

thank to the SensorKlear Loupe<br />

with LED illumination. Its focus is<br />

adjustable to cover different<br />

sensor sizes and it rests<br />

securely on the lens mount.<br />

There’s also a very useful<br />

opening on the side so you can<br />

clean with the loupe in place.<br />

But while you get a great view,<br />

cleaning performance is hardly<br />

out of this world. The included<br />

Hurricane Blower will dislodge<br />

loose particles, however simply<br />

blasting air like this can result in<br />

dust being blown onto the<br />

sensor. A better tactic is to use<br />

the SensorKlear II cleaning pen.<br />

Its hinged tip ensures a good<br />

contact with the sensor, though<br />

it doesn’t attract debris quite as<br />

effectively as the SpeckGrabber<br />

or Dust-Aid Platinum tools.<br />

VERDICT<br />

Pros: Decent loupe gives a perfect<br />

view for cleaning<br />

Cons: Blower isn’t always effective;<br />

won’t remove oil or stains<br />

We say: A reasonable kit for the<br />

money, but you can do better<br />

VisibleDust<br />

Arctic Butterfly<br />

724 Super Bright<br />

£100/$100<br />

www.visibledust.com<br />

Here’s an electric brush<br />

designed to attract dust away<br />

from your sensor via the<br />

wonders of static charge.<br />

The brush’s ultra-fine bristles<br />

are attached to a rotating shaft<br />

driven by a pair of AAA batteries<br />

in the handle. Ten seconds of<br />

spinning prior to cleaning<br />

causes a centrifugal force that<br />

both ejects dust from the brush,<br />

and, with the help of the fibres’<br />

nano-coating, recharges the<br />

bristles’ static attraction. Then<br />

with the brush stationary again,<br />

lightly drag it across your sensor<br />

to pick up any loose particles.<br />

A pair of LEDs light your way,<br />

which is especially important as<br />

you don’t want the bristles to<br />

contact areas surrounding the<br />

sensor, due to the risk of debris<br />

or mirror lubricant getting<br />

dragged onto the sensor.<br />

Loose dust is picked up pretty<br />

well, but the brush doesn’t hold<br />

on to particles as reliably as the<br />

SpeckGrabber, making the high<br />

price hard to justify.<br />

VERDICT<br />

Pros: Easy and fun to use; fairly<br />

effective for removing dust<br />

Cons: Premium price, yet will only<br />

clean dry debris; no loupe included<br />

We say: It’s a novel concept, but<br />

the cost is high for limited versatility<br />
