Greetings again everyone and today I'm Excited to be presenting my first ever Review of a medium format camera lens The Fuji gf80 mm f1.7 Rwr which is only for Fuji's gfx system Cameras the maximum apture of f1.7 makes It one of the brightest lenses available On gfx and for those curious this lens Is the fullframe equivalent of 63 mm With the equivalent depth of field of About 1.3 or so so it's short telephoto With a capacity for beautifully outof Focused backgrounds lending itself Perfectly to Portrait and subject Photography as well as all kinds of Other things the landens costs $2,300 or about £22,000 here in the UK Although at the time of writing it can Often be found for about 20% off so it's Expensive but still potentially one of The most useful and creative lenses on The system I'd like to thank Fugi UK for Learning me this optic for a few weeks Over Christmas for evaluation as well as A 100 megap camera to test it on but This is still a totally independent Review the lens might have a great Reputation but we'll be looking out for Weaknesses now the first thing you Notice about it is that obviously it's a Big lens and at 800 G or approaching 2 It has a bit of weight to it for sure Although the build quality it makes of Plastic and metal feels fantastic in the
Hands the lens is weather sealed in all The relevant places as you'd expect in This price range at the rear we get an Aperture control ring which turns with Nice tactile clicks every third of an F-stop and can be locked in or out of Automatic mode with a button on the side Then comes the rubberized Focus ring it Turns lovely and smoothly but the lens Motor's response is poor being really Quite jerky as as you can see in this Footage which also demonstrates the Focus breathing that jerky Focus Response touches upon this lens's main Weakness slow autofocus the lens's Autofocus motor is slow and noisy in use As you can see here and Here it gets on with its work Begrudgingly with the deflated air of a High school basketball coach whose Professional life hasn't quite gone to Plan it is also not able to keep up with Rapidly moving subjects although slower Subjects should be fine the main thing Though is that the auto focus system is At least accurate when it does catch you There and it is the lens has a front Filter size of 77 mm and it comes with a Nice deep Hood the lens does not feature Image stabilization although the newest Fuji gfx camera is feature it builtin Overall the build quality is quite Lovely here although its size is Consider durable and it's autofocus
Pedestrian let's move on and look at Image quality I'll be testing the lens On a gfx 100 Mark I camera with its 102 Mapel sensor in camera Corrections are Turned on for this test in the middle of The image we see fantastic sharpness and Quite good contrast even at 102 Megapixels but we're also catching a Little purple fringing on contrasting Edges over in the corners we still see a Surprising amount of sharpness here but Contrast is certainly being spoiled by Ghosting on contrasting edges still Considering the resolution we're Shooting at I'm quite pleased here if You sto down to F2 then we notice Slightly better contrast in the corners And back in the middle that purple Fringing is virtually gone stop down to F2.8 and it's totally gone leaving Behind a truly spectacular image over in The corners contrast has increased quite A lot although the resolution lags Behind the middle just a little there's An improvement at F4 but at f5.6 the Lenses razor sharp now from corner to Corner nice f8 and f11 look about the Same but at F16 the effected defraction Rob us of a little resolution still over All it's a great performance from this Lens on such a ridiculously demanding Sensor it's true that you have to stop It down for the best results but really The resolution is more than sharp enough
For most users even at F1.7 okay let's bypass in camera Corrections by processing some war Images with thirdparty software and Looking at Distortion and vignetting the Lens projects just a touch of Bin Cushion Distortion here but quite strong Vignetting at f1.7 at f2 f2.8 and F4 Those Corners gradually brighten up with A minimum Focus distance of a rather Long 70 CM this thing will definitely Not be getting confused for a macro lens Anytime soon soon but thankfully closeup Image quality is virtually as good here As it was at normal distances with Plenty of sharpness at f1.7 willbe it With purple fringing again at f2 that Fringing is virtually gone and at f2.8 We enjoy a perfect close-up image now Let's see how the lens works against Bright lights and it's a performance on The good side of average here I'd say Small amounts of flaring and glaring are Definitely visible but thankfully it's Nothing too intrusive and while we're Working in the dark let's take a look at Coma levels as I suspected from the test Chart pictures coma is definitely Present here with smearing in the Corners at F1.7 but you should remember this is A2 Megapixel image which really emphasizes The issue stopping down to F2 greatly Reduces that smearing and at f2.8 it's
Gone only to be replaced by small Sun Stars stop down to f8 for those Sun Stars to get nice and strong and at f11 And F-16 they get pretty big nice let's Take a look at the quality of this Lens's Baker a real pleasure on a medium Format camera and really that's another Of this optic strengths these Backgrounds look gorgeous and smooth With no real issues apart from the Typical cat ey shape to specular Highlights in the corners I love it and Finally related to to bka comes Longitudinal chromatic aberration at F1.7 it's perfectly apparent here it's Still there at f2.8 and even a little at F4 although at f5.6 it's finally gone Well then what a fascinating Introduction to the world of medium Format Optics the gf80 mm f1.7 rwr is a Truly great optic and one of the most Useful on the gfx system with a couple Of caveats the lens struggles a little With image quality in its Corners at the Brightest aperture but but stop down Just a little for those issues to mostly Clear up leaving behind excellent image Quality from corner to corner longer Tudinal chromatic aberration is also a Little high and that autofocus motor it Autofocuses with the pace and the noise Of a lens from the 1990s although thankfully it does at Least work accurately other than that
The lens is very sharp even when Contending with a 102 map sensor and With very high contrast beautiful bker Nice sunstars honestly if you have Enough money to buy an expensive gfx Camera then a lens like this should Probably be one of the first on your Shopping list to take advantage of sad Camera so despite a few flaws to be Noted it definitely still comes [Music] Recommended I had a fun Christmas with That Medium format camera it was a real Voyage of Discovery for me although Actually trying to get sharp 102 megapix Images is no joke anyway thanks for Watching everyone and if you find these Reviews helpful or even just plain Interesting then check out my patreon Page in the description below where Supporters get all kinds of exclusive Bonus content and make a huge difference To keeping this channel going ciao for Now everyone
