THIS IS WHERE THINGS GET
INTERESTING! IT'S OVER TWO YEARS SINCE SONY SHOOK UP THE COMPACT CAMERA MARKET
BY PUTTING A 1"-TYPE SENSOR INTO A GENUINELY POCKETABLE COMPACT. THE CYBER-SHOT RX100 LOOKED A LOT LIKE ONE OF
CANON'S S-SERIES OF HIGH-END COMPACTS BUT USED A SENSOR 2.8 TIMES LARGER TO
OFFER A SUBSTANTIAL INCREASE IN IMAGE QUALITY.
AMAZINGLY, SONY HAS REMAINED
UNCHALLENGED IN THIS FIELD FOR OVER TWO YEARS, IN WHICH TIME IT'S MANAGED TO
INTRODUCE TWO MORE GENERATIONS OF RX100. THE RX100 III BROUGHT
AN ELECTRONIC VIEWFINDER AND A MORE CONSISTENTLY BRIGHT (ALBEIT SHORTER) ZOOM,
HELPING IT CLIMB EVEN FURTHER BEYOND THE COMPETITION. THAT ESSENTIALLY
UNCHALLENGED SUPREMACY ENDS WITH THE ARRIVAL OF CANON'S POWERSHOT G7 X.
LIKE THE RX100 III, THE G7 X OFFERS
A 1"-TYPE, 20MP BSI SENSOR MATED TO AN F1.8-2.8 ZOOM STARTING AT 24MM
EQUIVALENT. THE TWO CAMERAS ARE ALSO SIMILAR IN SIZE AND OFFER BROADLY SIMILAR
FEATURE SETS. WHICH IS GREAT FOR PHOTOGRAPHERS, BECAUSE IT MEANS THE SONY
FINALLY HAS SOME PROPER COMPETITION.
POWERSHOT
G7 X KEY FEATURES
- 20MP 1"-TYPE BSI CMOS SENSOR (13.2 X 8.8MM)
- 24-100MM EQUIV. F1.8-2.8 LENS
- CLICKING CONTROL DIAL AROUND LENS
- FLIP-UP REAR TOUCHSCREEN
- DEDICATED EXPOSURE COMPENSATION DIAL
- 3.0" 1.04M DOT LCD (720 X 480 PIXELS)
- BUILT-IN ND FILTER
- WI-FI WITH NFC
·
CANON IS ONE OF THE ONLY MANUFACTURERS TO
HAVE CONSISTENTLY OFFERED A DEDICATED ENTHUSIAST COMPACT CAMERA IN ITS LINEUP,
AND THE ARRIVAL OF THE G7 X MEANS IT NOW OFFERS FOUR: THE S120, G16, G7 X AND
G1 X MARK II, EACH OFFERING A DIFFERENT BALANCE OF SIZE, PRICE AND CAPABILITY.
THE STYLING AND SIZE OF THE G7 X MAKE IT LOOK LIKE AN S-SERIES, BUT THE DEGREE
OF DIRECT CONTROL JUSTIFIES ITS G-SERIES MONIKER.
·
THE CAMERA'S COMBINATION OF TOUCH SCREEN,
DEDICATED EXPOSURE COMPENSATION DIAL AND CLICKING CONTROL DIAL AROUND THE LENS
GIVE A HIGH DEGREE OF DIRECT CONTROL FOR SUCH A SMALL CAMERA AND CANON'S
ITERATIVE, EVOLUTIONARY APPROACH TO CAMERA INTERFACES, ALONG WITH A LITTLE TIME
SPEND PLAYING WITH THE CAMERA SUGGESTS IT SHOULD WORK PRETTY WELL.
·
MEANWHILE, THE DETAILS OF THE SENSOR STRONGLY SUGGEST IT
USES SONY'S IMX183CQJ SENSOR,
SO COULD WELL BE ABLE TO MATCH THE LATEST RX100 SERIES IN TERMS OF IMAGE
QUALITY. THAT ALONE WOULD MAKE IT A SIGNIFICANT ADDITION TO THE MARKET. THE G7
X IS JUST AS SMALL AS THE SONY BUT OFFERS MUCH MORE IN TERNS OF DIRECT CONTROL.
·
THEN, OF COURSE, THERE'S THE LENS:
·
THE LENS
·
GIVEN THAT IMAGE QUALITY IS ALL ABOUT LIGHT
CAPTURE, THE BEST WAY OF MAKING THE MOST OF A LARGE SENSOR IS TO MATE IT WITH A
BRIGHT LENS. ONE OF THE THINGS THAT HELPED THE RX100 III EARN ITS GOLD AWARD
WAS THE INCLUSION OF AN F1.8-2.8 ZOOM WHICH MEANT THE CAMERA MAINTAINED MUCH
MORE OF ITS LARGE SENSOR ADVANTAGE AS YOU ZOOMED IN (RATHER THAN STIFLING IT
WITH THE F4.9 MAXIMUM APERTURE AT TELEPHOTO ON THE FIRST TWO RX100S). HOWEVER,
THIS SPEED BOOST CAME AT THE COST OF THE LENS' RANGE, WITH SONY RESTRICTING THE
ZOOM TO A 24-70MM EQUIVALENT RANGE TO KEEP THE CAMERA SMALL.
·
CONSEQUENTLY, IT'S INTERESTING TO SEE CANON
FIT A 24-100MM EQUIVALENT LENS INTO THE G7 X WHILE ALSO OFFERING A F1.8-2.8
MAXIMUM APERTURE RANGE.
·
CLEARLY CANON HAS FOUND SOME WEIRD TRICK THAT
HAS LET IT COMBINE A FAST MAXIMUM APERTURE RANGE WITH A USEFULLY BROAD ZOOM
RANGE, WHILE KEEPING THE CAMERA SIZE DOWN. NOTE, ON THE GRAPH ABOVE, HOW THE G7
X'S MAXIMUM APERTURE STAYS BRIGHT FOR MUCH LONGER THAN THE RX100 III'S. THEY
MAY OFFER THE SAME RANGE ON PAPER, BUT AT ANY POINT FROM 24-50MM EQUIVALENT, THE
CANON'S LENS CAN BE KEPT WIDER-OPEN THAN THE SONY'S, WITH THE DIFFERENCE
REACHING OVER 2/3EV AT 30MM EQUIV.
·
WHAT THE ABOVE GRAPH SHOULD MAKE CLEAR IS
THAT THE G7 X IS AMONGST THE MOST CONSISTENTLY BRIGHT COMPACTS ON THE MARKET,
ONCE SENSOR SIZE HAS BEEN TAKEN INTO ACCOUNT, WHICH SHOULD GIVE EXCELLENT
CONTROL OVER DEPTH-OF-FIELD (INCLUDING AT FOCAL LENGTHS USEFUL FOR CLASSIC
PORTRAITURE) AND LOW LIGHT PERFORMANCE. GIVEN THE VERY HIGH LIKELIHOOD
THAT BOTH CAMERAS USE THE SAME (EXCELLENT) SENSOR, IT'S REASONABLE TO EXPECT
THE CANON'S IMAGE QUALITY TO BE PRETTY COMPETITIVE, IF ITS LENS IS ANY GOOD.
·
ONLY PANASONIC'S DMC-LX100 IS ABLE TO OFFER
MORE LIGHT CAPTURING ABILITY AND THAT'S A BIGGER CAMERA WITH A MORE RESTRICTIVE
ZOOM RANGE (THOUGH WE ALSO THINK THAT'S HUGELY APPEALING, DEPENDING ON YOUR
EXACT NEEDS AND TASTES).
OUR VERDICT
CANON DIDN'T NEED TO DELIVER A MAJOR OVERHAUL
OF ITS EXCELLENT G7 X, AND THE UPGRADES IN THE G7 X II BUILD ON THE ORIGINAL
CAMERA'S REPUTATION, PARTICULARLY THE PERFORMANCE-BOOSTING DIGIC 7 PROCESSOR.
THE ONLY DISAPPOINTMENT IS THE CONTINUED ABSENCE OF A VIEWFINDER.

CAPTURE
CAMERAS WITH A ONE-INCH TYPE SENSOR ARE POPULAR RIGHT
NOW, WITH SONY AND PANASONIC INCLUDING THEM IN THEIR PREMIUM COMPACT CAMERAS
ALONG WITH CANON, WHOSE POWERSHOT G7 X MARK II IS ITS LATEST CAMERA TO FEATURE
ONE. A ONE-INCH SENSOR IS LARGER THAN THE SENSOR IN A TYPICAL COMPACT, AND THE
MAIN BENEFIT IS IMPROVED IMAGE QUALITY, ESPECIALLY IN LOW LIGHT CONDITIONS.

1080P VIDEO CAPTURE
THE G7 X MARK II
SUCCEEDS THE G7 X IN THE MIDDLE OF CANON'S HIGH-END G SERIES RANGE OF
COMPACT CAMERAS. NOT A HUGE AMOUNT HAS CHANGED FROM THE PREVIOUS VERSION, BUT
THERE ARE SOME SIGNIFICANT, IF INCREMENTAL, UPDATES.
THERE'S STILL THE SAME 20.1 MILLION-PIXEL CMOS SENSOR,
AND A 4X OPTICAL ZOOM LENS THAT OFFERS AN EQUIVALENT FOCAL LENGTH OF 24-100MM
AND COVERS AN APERTURE RANGE OF F/1.8-F/2.8.
A COUPLE OF
MINOR CHANGES HAVE BEEN MADE TO THE EXTERIOR OF THE CAMERA, BUT PERHAPS THE
BIGGEST UPGRADE OF NOTE IS THE ADDITION OF A DIGIC 7 PROCESSOR, THE NEWEST
AVAILABLE IN ANY CANON CAMERA. THIS BRINGS WITH IT UPGRADES TO SHOOTING
PERFORMANCE, INCLUDING A FASTER BURST SHOOTING RATE.
FULL HD VIDEO RECORDING IS AVAILABLE, ALTHOUGH THERE'S
SADLY NO SIGN OF 4K YET FOR CANON'S COMPACT CAMERAS. WI-FI AND NFC CONNECTIVITY
IS PRESENT, WHILE THE TOUCH-SENSITIVE SCREEN TILTS TO ENABLE SHOOTING AT
AWKWARD ANGLES; HOWEVER THERE'S NO BUILT-IN VIEWFINDER, AND, WITH NO HOTSHOE OR
ACCESSORY PORT, NO OPTION TO ADD ONE EITHER.
