MiNT just releases InstantFlex TL70 2.0, their second generation of twin lens instant camera, together with a lens set particularly for TL70. The set includes three ND Filters – ND2, ND4 & ND8, Close-up Lens and Lens Hood. We are pleased to get the set before it has officially released and now we can’t wait to share our experience with you!


CLOSE-UP LENSinstant-university_yellow-border

For InstantFlex TL70, the closest shooting distance is 48cm. With applying the Close-up Lens, you can shoot as close as 18cm.

You can take a close-up shot without leaving much background, at the same time, create a shallow depth of view image (by using a big aperture like f/5.6).


NEUTRAL DENSITY FILTERS – ND2, ND4, ND8 ✮instant-university_yellow-border

The set includes three ND filters and you may wonder when and which you are required to use them.

The use of ND Filter is to speed up the shutter. Actually, the difference among three ND filters is their intensity to reduce the amount of incoming light entering the camera. ND8 can block the most of light while ND2 block the least.

Fuji mini film has high ISO of 800 while it has high sensitivity to light. Especially when you shoot in outdoor, the sunny/ bright condition will easily lead to an over-exposed photo. Under this circumstance, you have to decide which ND Filter to use in order to obtain a satisfactory image.

When there is a red light shown in viewfinder, it means the shutter speed of camera is now 1/500. The relatively slow shutter speed allows excess amount of light entering the camera, tends to create over-exposure image.

The solution is easy. You can download a smartphone light meter to assist, it helps to achieve a correct exposure. For ISO, set it as 800 (default ISO of Fuji mini film). For aperture, set it the same as which you set on your TL70. Then you will get a number of time automatically.

If the time shows “1/1000”, you need to apply ND2 for shooting. If the time shows “1/2000”, use ND4. If the time shows “1/4000”, use ND8.


LENS HOODinstant-university_yellow-border

As long as protecting the lens, the hood can avoid glare and lens flare. So basically you can apply the hood always.

Since last lecture, you have known an important element in Photography: the Exposure Triangle. You learn that the aperture value controls depth of field. In fact, there are
2 more critical factors affecting depth of field.


FACTOR 1: THE FOCUS DISTANCEinstant-university_yellow-border


Focus distance is a calculation from the subject to lens. By changing the focus distance, you will get different depth of field of an image. If you are closer to the subject you are focusing on, you will have an image with shallower depth of field, and vice versa.


FACTOR 2: THE FOCAL LENGTHinstant-university_yellow-border


Focal length (usually measured in mm) is a calculation of an optical distance from the convergence point in the lens to the sensor or film inside the camera, but IS NOT the actual length of a lens. Basically, the longer the focal length, the narrower the angle of view and the more magnifying effect in your picture with shallower the depth of field, and vice versa.

**Shallower lens (e.g. 200mm) → longer focal length→ shallower view captured + shallower depth of field → telephoto effect
**Wider lens (e.g. 28mm) → shorter focal length → wider view captured + deeper depth of field
