The User's Review: Quantaray 2X (4 elements) vs. Kenko 2X MC7 (7 elements) Extenders, both with Minolta/Sony A Mount and 8 pins

1. The Quantaray 2X with 4 elements is more compact/smaller.
2. The Kenko 2X with 7 elements provides higher resolution (see the last image)
3. However, the longer tub and more glass in the Kenko 2X may need more light compensation.

The test devices used were a Minolta Maxxum 50mm F2.8 Macro Lens and a Sony A230 camera.

The User's Review: Yashica YEM35 Super Light Meter, 1967

This is a battery-powered meter, well made, with metal top cover and plastic bottom.Behind the shoe, there is a zero adjust screw. The required PX625 mercury battery is not manufactured today.
