As pointed out in the specifications, the aperture ring is stepless, this again rotates smoothly. Used wide open the Zhongyi Mitakon with it’s amazing f0.95 and focused to minimum distance has a depth of field of several millimetres whereas the Andoer wide open has a depth of field of 15 millimetres, both are very useful.<\/p>\n What are the lenses like in use?<\/p>\n We took them outside to find out!<\/p>\n The test set up.<\/strong><\/p>\n Fuji X-T1 fitted with Andoer 25mm f1.8 The tests<\/strong><\/p>\n Our first test was to check for vignetting, for this both cameras were pointed at an even blue sky and exposures were made with the lens set to infinity with aperture wide open, f4 and f16.<\/p>\n Secondly we tested for sharpness, again both lenses were a sharp in the center but a little soft at full aperture, by f4 both lenses were sharp across the frame and remained consistent through to f16.<\/p>\n For our third test we set both cameras on a building in the distance (infinity). The lenses were focused visually and an exposure was made at f16, we then fitted the relevant adapter and Nikkor lens to each setup again visually focusing and using an aperture of f16. It is worth pointing out that the Nikkor lens has seen better days, but since it was a fixed focal length, closest focal length and similar element grouping, rather than a zoom lens with twice the number of elements and more complex lens groups.<\/p>\n Conclusions<\/strong><\/p>\n The images from both camera setups were viewed on a colour balanced and profiled monitor.<\/p>\n Both lenses displayed vignetting in the corners when used wide open, the Zhongyi Mitakon improving at f4, whilst the Andoer took to f5,6 to achieve the same result and both lenses were clear of vignetting by f16.<\/p>\n <\/p>\n Compared against the Nikkor lens, both the Andoer and the Zhongyi Mitakon lenses appeared a little cooler in colour rendition but certainly nothing to worry about.<\/p>\n Image appeared darker with the Zhongyi Mitakon\u00a0 on Panasonic, however this could be due to in camera image processing<\/p>\n Sharpness wise the Nikkor showed it’s age being slightly softer against the other two lenses.<\/p>\n Contrast, again the two new lenses had better contrast than the Nikkor, although strangely the Nikkor image reproduced flatter on the Fuji.<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 \u00a0 \u00a0 \u00a0 Andoer 25mm<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n Nikkor 24mm on Fuji<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n Andoer 25mm crop<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n Nikkor 24mm crop on Fuji<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n Zhongyi Mitakon 25mm<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n Nikkor 24mm on Panasonic<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n Zhongyi Mitakon 25mm crop<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n Nikkor 24mm crop on Panasonic<\/p>\n A handy hint, since both lenses have manual aperture rings, focus with the aperture wide open then stop down to take the photograph<\/p>\n As an aside at a later date we will do some additional tests with the Andoer and Zhongyi Mitakon comparing them with zoom lenses at the same focal length.<\/p>\n Which lens to buy?<\/strong><\/p>\n Both lenses are a delight to use and and give great results.

\nDespite the extra number of lens elements in the Zhongyi Mitakon lens the weight difference is barely noticeable.
\nFilter thread is 43mm on both lenses.
\nWhere the lenses differ is in their optical arrangement, the Zhongyi Mitakon has a lot more glass – 11 elements in 9 groups (and some of these elements extra low and low dispersion glass) plus a maximum aperture of f0.95, as opposed to 5 elements in 3 groups and no mention of low dispersion glass and a maximum aperture of f1.8. Both lenses however have multicoated optics. Another difference worth noting is that the Andoer lens has the aperture ring at the back\u00a0 (a fairly standard arrangement) and the focus ring which is nicely scalloped at the front. The Zhongyi Mitakon lens however has a ribbed focus ring towards the middle of the lens – Mark has fitted a zip clip to the focus ring to aid focusing. Whilst the aperture ring is set at the front of the lens.<\/p>\n
