The Schneider 35mm Componon is a classic professional enlarging lens. It is a 6-element, 4-group lens that is corrected for flat field, high contrast transfer, and excellent definition over the whole field. The high performance of the Componon is maintained even at high magnifications.

Mechanically, the Schneider Componon's also match the latest state of the art with illuminated aperture scales, click stops as well as stop-less aperture adjustments and with preset aperture controls.

Disengaging the click stop system permits precise fine adjustment of the aperture when working with color analyzers and other meter systems.

Once the lens is stopped down to the desired aperture, the preset control allows it to be reopened fully for cropping and/or refocusing, and then stopped down again to the working aperture shown on the luminous scale.

The Componon 35 f/4 lens is fitted in a barrel with lighted click stops and a 25mm rear mount.

Q: 1. is this a full frame lens? I have the Sony a7.

A: Yes, it's a full frame lens and will work on a Sony a7.

Q: 2. This lens is listed as an 35mm but also states 56mm in the information; what is the deal??

A: The lens focal length is stated in relation to a full frame sensor. This lens is 35 mm when used on a full frame camera. This lens can also be used on cameras with APS-C sensors.

Q: 7. Thinking of doing some astrophotography, and have a Nikon D3300, will this lens work for me?

A: This would not be ideal. 35mm on your D3300 wouldn't be wide enough for astro skies. I would recommend something like this instead. https://www.bhphotovideo.com/c/product/859173-REG/Samyang_SY14MAE_N_14mm_f_2_8_Super_Wide.html
