The MINT InstantKon RF70 camera
fills finally a gap that Fuji didn't want close. Fuji makes wonderful
film that could be professionally used, but only makes crappy cameras
with very limited specifications. The Mint camera has many features that other Instax
cameras do not have, as: rangefinder, extended automatic mode, manual mode, B mode,
long exposure times, built-in flash,
flash socket, multiple exposure.

some difficulties to get the
parcel, first it was stuck at the customs, then in a severe delivery
problem by the transport company. I had to drive a long way to get my
parcel. So unpacking was done in the boot of my car on a parking of the

opened, but can be shut off via the dial. There is a green LED if
exposure is o.k., red in all othe cases. The LED lamp flashes if the
flash is charged. In case of over-exposure, the LCD screen
indicates the ND filter value (2, 4 or 8), a very handy feature.

Size comparison again.
The camera is small as you can see from the pictures. If you ever had
Fujifilm GA645 or a GF670 (or a Voigtländer Bessa III), all made by
Cosina, you will love the camera, it seems to be enspired by these
models. It feels solid. Handling is easy if you are used to big
rangefinders, it's a big step forward for
Just to give you an idea, some first photos taken with this camera, all automatic mode (A):
∞, first photo on the motorway..
∞, Cassel, very sunny day.
∞, Cassel, severe backlight.
A, F22, 3m, Cassel.
A, F22, 4m, Cassel, beautiful car.
A, F22, 0.75m.
A, F16, 0.75m, R-sync flash with ambient lamplight.
A, F5.6. 2m, focus on the first candle, veranda on a very dull day. Shallow depth of field, as promised.
A+1, F16, 2m, very dull light in veranda.
A, F16, 2m with flash. The flash can help a lot and the exposure system gets it right.
There are more photos, more testing and a continued review on a second page here. And there is a new third page, an accessory page for tinkerers, but also for more information how to handle the camera.
My personal conclusion:
camera is much better than any other Instax camera I have (and I have
quite some...), much better than the Fuji AF500 as well. It can make
the photos Instax film deserves. Automatic mode gets it right in an
astonishing high percentage of cases. Manual mode gives you all the
possibilities you may want.
is easy, fluid and logic. All settings are easy. The ejection lever is
a good idea. If you take photos in quiet places, you can eject under
your coat or even outside. It also makes double or multiple exposure as
easy as possible.
The exposure system is fine. The automatic
exposure is very good, when you touch the shutter button, it lights a
green lamp if it's fine, red in all other cases. The lamp can't be
overlooked as it's next to the viewer. In case of over-exposure risk,
the camera gives the ND filter value (2, 4 or 8) on the LCD screen when
you touch the shutter button. That's a marvellous help. You can also
measure the important part of your picture by pointing the camera
towards it, half press the shutter and then frame your picture and
In manual mode you can use the exposure system as a light
meter. Half press the shutter and ajust speed or aperture until the
lamp is green. The error margin of the sytem wasn't bigger than that of
my Gossen DigiSix. Instax film has a strange sensivity behavior: in
strong sunlight it's 1600 ISO, in low light 400 ISO and only in between
it's 800 ISO. If you take this into account when metering, you get
perfect results. The camera compensates this behavior automatically, to
my taste it sometimes overcompensates a bit, which can be overridden with A+ and
The manual focussing is fine as well. The
separate rangefinder is less cumbersome than I
feared, its position just under the viewfinder makes it easy to use. I
have no problems with this rangefinder, it's big enough, easy to use
and gives good results.
camera powers up when unfolded. The struts do not fall into place, you
have to straighten them. There is an "Off" setting on the setting dial l if you
want to leave it open. To fold it again, you have to set the lens to
infinity and push the button under the lens, it folds as any folding
camera. You can leave a filter on the lens when folding, but I would
not recommend to do so, it's easily forgotten when you use it again.
camera feels solid for a camera with a plastic body. And then there is
the question of the price. Is it expensive? In my opinion, it's not.
This is a small series of hand-assembled cameras, nearly all parts had
to be custom made. Compare it to the few modern medium format folders
that are still on the (second hand) market. A Bessa III is about 3
times the price. The Fuji GF670 doesn`t count, as it can no longer be
repaired. A Makina? Twice the price at least. And this is a new camera,
it has a 5 years warranty. So no, seen what you get it's not expensive.
point to their advantage: Mint does deliver serious customer service.
As I was in the first bunch of delivery and as I was really waiting for
a serious Fuji Instax Wide Film camera, I did extensive testing with
the new camera. When I had some minor problems with it, Mint was easy
to access and give further advice. As my camera had some
inconsistencies with exposure or diaphragm, they immediately proposed a
replacement camera. And they kept their promise: they sent the
replacement as soon as possible. They even sent me 2 filter holders to
be able to build accessory holders! (see new accessory page.)
The new camera is an improvement. The dial has firm clicks that will
not move inadadvertently. The closing mechanism has improved. And, most
important, the exposure system is more reliable. They really did a good
there will be a cheaper, automatic only version in the future. Why do I
think so? In the manual, there are 2 versions, the one I have and an
all automatic one. So maybe....
There are a few things which I would like to see:
- a lens shade, as the lens is prone to flare. EDIT: solved, see accessory page - a threaded adapter for stardard lens accessories. EDIT: solved, see accessory page -
a tripod socket centered between front and back. It's very close to the
front. As I use Rapid Connect plates, these are not as solidly fixed as
they could be. - an automatic night mode like the Lomo Wide - firmer clicks on the setting dial, it can be moved inadvertently. EDIT: solved, better on my replacement camera - a longer course of the shutter button - a strap lug on the top of the left side to be able to attach a grip - a less fiddely button to close the camera. EDIT: solved, much better on my replacement camera - a standard PC flash socket or a hot shoe.
make it clear: these are just minor concerns which could be taken
into account if the camera evolves. As you can see, between the first
series and my replacement camera, it already evolved. There is no
perfect camera. This
one is already extremly fine as it is.
