The User's Rewivw: Sun Opt. 38-90mm 3.5 Macro Zoom Lens, with 5 turning rings

This lens catches my eyes with its five (5) turning rings on its barrel, probably the lens with the most rings I have ever seen. The focus and macro rings, but not the zoom ring, change the lens length when turned while only the macro ring when turned moves the rear element. The highest macro rate is 1:4 on this lens.

 

 There is a hood (67mm) on the lens as showed in the last image. However, I am not sure if the hood is original.

 

The User's Review: Pentax ZX-M 35mm Film Camera

 

The light-weight and auto-film-advance body with LCD displays (one on should and the other on the right side of viewfinder) needs a Pentax-A lens in order to use the A/Programed shutter function.

The User's Review: Vivitar V2000 35mm Film Camera

A simple and easy-to-use body, similar but better than Pentax K1000 in terms of specs. The body also has a Pentax K mount.

The front and back body surfaces are covered by a rubber layer, comfortable to hold.

On the left side of viewfinder, from top to bottom, there are +(red), o(green) and -(red) LCDs to indicate the light meter measurements.

V2000 might indicates the highest shutter speed, 1/2k sec.

V2000 might indicate the highest shutter speed, 1/2000 sec.

Good is the metal tripod screw hole, strong and durable to use. Bad is the thin plastic battery, easy to fall apart.

The User's Review: Fujica AX-3 35mm Film Camera and Auto Winder X, released in 1980

This was my first time to hold a Fujica camera although I had known this brand for many years. Without its instruction, I took a few minutes to figure out the power-on/off switch and the self-timer. Its battery cover can be taken off and its rewind button is located by the film advance lever. In the viewfinder, the shutter speed scale and aperture window are placed on left and top, respectively.

I saw two color versions (chrome and all black) of AX-3 

The User's Review: Sigma sa-1 35mm SLR Camera with Quartz Control

This Sigma model is closely related to Ricoh XR-7 and Sears KS-2. They all have a Pentax K mount. SA-1 has two handle pads for your right hand, and has the AE lock on the front right hand pad (easier to use with right hand only). However, SA-1 has no multiple exposure although the DOF levers. on the three models are the same.

Its build quality is very good.
