but I would like you to understand

Thank you

This is the fourth eye-level finder design of Asahi Optics’s film SLR cameras!

This time we will look at the eye-level finder design of this film SLR camera released in 1973, comparing it with the SV released in 1962.

ASAHI PENTAX SPOTMATIC F  (Reference product)

This is a steel-bodied film SLR camera released in 1973.


Comparison with SV. 
The part where the maker’s logo is placed is very similar but slightly different in shape.
The maker’s mark and the maker’s logo are the same.


An angle from an angle. 
An accessory shoe is attached.

Comparison with SV.
There is a difference in the shape of the rear end of the side surface and the presence or absence of anaccessory shoe .


View from the side.
An accessory shoe will be attached.

SV, but the angle toward the rear edge of the top surface is almost the same.

Top surface.

From the top, there is a difference in the shape of the apex and the surface going backward due to the accessory shoe.


This is the back side. You can clearly see that the shape is quite different.
The viewfinder frame is almost the same.


In this article, we compare the old and new eye-level finders of Asahi Optics’s film SLR cameras.

The 1973 release SPOTMATIC F compares very well with the 1962 SV.
The design of the apex of the eye-level finder has changed to accommodate an external strobe terminal. This is the same for all manufacturers, so I think it is an evolution of the times.

We will continue to introduce eye-level finder designs in the future.

Thank you for reading to the end!
