today we look at the Olympus om 50 millimeter F one point eight lens and see how it performs in modern cameras such as the aps-c sony a6000 and the full-frame sony a7 mark two oh emmalin says that this era are very well built indeed with all metal construction however these lenses are also very compact which make them an attractive choice when pairing with modern mirrorless cameras which are also small the OEM to e-mount adapter adds a

better size but it's still overall a small package and a good match for these cameras the focus ring is smooth and precise which should be good news for those interested in video making the aperture ring moves in one stop increments starting from a minimum FF 1.8 up to f-16 the OEM is capable a very
01:33
sharp in contrast the photos especially when stopped down a little bit to have 5.6 or F a manual focusing can be difficult and slow so this is probably not the lens for street photographers however owing to the F 1.8 aperture you can actually get some very decent Boca with this lens I measure sharpness in a controlled live environment with artificial lights and
02:08
the solid support for both the camera and the target this target is a special design target for sharpness measurements using the slanted edge technique I use the excellent free software MTF mapper developed by dr. Franz Vandenberg to process the data this is a great tool that dr. Franz made available to anyone through sauce forge and it's a software that I highly recommend to better visualize the results I developed custom
02:40
software that produces 3d plots showing the sharpness across the frame at each aperture these graphs are very easy to interpret the x and y axis corresponds to the sensor area which in the 24 megapixel cameras i'm using are 6,000 by 4000 pixel grid it's on the other hand the z-axis color in height is proportional to sharpness higher Z values correspond to sharper areas and lower Z values to softer ones in this
03:12
example which is typical for many lenses we see that the center area is substantially sharper in the edges we start our evaluation with the 24 megapixel aps-c sensor found in the sony a6000 most lenses are softer wide open and this lens is no exception being actually quite soft at F 1.8 things do we improve sharply at F 2.8 with center sharpness being quite good already this
03:46
will be a good setting to use for portraits where you want the eyes and face in focus while blurring the corners by F 5.6 and f/8 the performance seems to peak though the corners never really get very sharp in this lens moving on now to the full-frame sensor in a 24 megapixel Sony a7 Mark 2 at f11 8 the story is identical to what we saw with ApS that was expected the large sensor does reveal more of the optical
05:03
imperfections in the corners thankfully things get much better left to pronate and beyond where the lens actually delivers a very respectful performance even slightly better than what we saw using the aps-c sensor flaring resistance is usually a function of the lens coatings with modern coatings having made much progress in this run surprisingly for a lens this old the OM 50 millimeter delivers a very respectful performance here flaring does

occur but is relatively mild and well controlled one of the advantages of a fast f1 point influence is the ability to render smooth out of focus background or bokeh at the maximum aperture we can see that the bokeh is smooth indeed even though it takes a somewhat oval shape I have two point eight one starts to see the shape of the aperture blades six of them in this case a fine bokeh is a very subjective topic for the most part and
07:15
it seems to me that the bokeh here is quite pleasant it's smooth enough and it's not distracting when it comes to chromatic aberration this lens is an average performer with some purple fringing visible at F 1.8 and F 2.8 though the issue is mostly gone at f/4 and Beyond 15 millimeter prime lenses
07:46
tend to perform quite well in this area than my experience so in this case I do find the barrel distortion to be a bit higher than expected in any case this is easily corrected in either Photoshop or Adobe Lightroom vignetting is also quite high especially at f12 innate in a full-frame camera where the corners are quite dark once again this is not a big issue nowadays in Photoshop and Lightroom can easily correct the exposure
08:19
being a fully manual lens the OEM 50f 1.8 does not include any optical stabilization however the beauty of modern mirrorless cameras within sensor image civilizations such as the a7 mark to set this feature will work with any lens that you attach to it to enable this feature on their a seven mark to go to the main menu and move to the seventh submenu page containing the steady shot settings be sure that steady shot is on
08:52
under the sellers shot settings select the correct focal length or fifty millimeter in this case and you are all set in this handheld test shot you can clearly see that the is help stabilize the lens quite effectively so now you have a 50 millimeter f-18 stabilized lens the Olympus om 50 f 1.8 foot is a very common lens in its days many copies were produced and shipped as kit lenses with Olympus om bodies because of this
09:25
the 50 mil is they're actually a very affordable S this histogram shows the prices this lens sold for online over the last three months as you can see the average price is only $30 or so while the om 50 ref 1.8 won't break any performance records when it comes to corner to corner sharpness for example it's still a very good choice for aspiring video makers or portrait photographers on a budget it's very well built and it's a very fun lass to use

with modern mirrorless cameras such as this Sony a7 mark 2 thanks for watching and if you enjoyed this video please support the channel by subscribing liking it and sharing with your friends
