Fujinon MK Series Review

Today we are looking at a pair of the MK series Fujinon lenses. They’ve been available for a while now but they deserve your attention. These are Cine Zoom lenses which cover a huge range. One lens does 18-55mm and the other one covers 50-135mm. So they are very flexible. Both lenses are super light and considering what they are capable of, compared to similar lenses on the market, they’re not priced too bad either considering what you get. Each lens goes for approximately 3.999,- euros. This is not cheap, but again keep in mind compared to a similar specced set of cine lenses in the same category, they aren’t really that expensive at all.


Let’s look at some of the features. Both lenses have a constant T-stop of 2.9 across the entire zoom range. This is very important for filming, where you are trying to get a consistent exposure when dealing with multiple scenes, shot on different days, from different angles, etc. So if you have both these lenses set to T2.9, then you know that both those lenses are exactly at 2.9.

The lenses are also parfocal, so they stay in focus when the magnification or the focal length is changed. Again, for cinematography, this can be very important. There’s also a built-in macro feature, they are supposed to have great 4K optical performance, a T-Stop of 2.9 giving you a fast aperture for a shallow depth of field, and they’re very well built and compact too and not too heavy.


The macro mode is interesting. There’s a little switch at the bottom of the lens which will set it to Macro mode, if needed. This can be quite convenient if you want to do a quick closeup. No need to take off the lens and swap it for another one and which makes it easy to switch from traditional shooting mode.


All in all we found these Fujinon lenses to be great all-rounders. They offer very good optical quality in a relatively compact, lightweight design. Even though they’re not cheap they’re not that expensive either, for a cine zoom lens with so much flexibility this is quite affordable. Sure, for the entry-level filmmaker it will not be cheap, but in the context of cine zoom lenses there’s nothing quite comparable and I would certainly recommend looking at these lenses.

The lens was also a pleasure to use. Focusing was smooth and easy to do by hand or with a little help from a focus puller. There was also no noticeable breathing when focusing, something which usually tends to be more visible in zoom lenses. Fortunately not here, frame size appeared to remain quite the same to me. As I mentioned before, the zoom is also parfocal and for filming this is a blessing. And of course, the constant aperture is a joy. There’s absolutely NO change in exposure when zooming in. NONE.

Basically these lenses to me are phenomenal.

So to sum it up. I highly recommend both of these lenses, together as a set since they so well complement one another, or on their own. Find more info here.
