Another Look at the Air Ministry 5 Inch f4 Lens

The Air Ministry 5 inch f4 lens is one of the more enjoyable lens to use, partly because it shows no haze or white spot in the picture, often associated with old lenses that are uncoated. Of course the lens needs the proper shade (all lenses should have proper shades). This is quite amazing because the lens itself shows some haze when look through it.

More interesting is the optical characters of the lens. I don't know if it's due to the design, or glass, or other reasons, the rendering of the pictures look markedly different the modern lenses, especially when it comes to out of focus area. Maybe this is part of the allure of old lenses that I enjoy so much.

Can't wait to shoot this lens again.

    (and of course i stick to this hobby till now)
    i thank you for that and wish you a nice time.


    1. Hi Michael, thanks for your kind words. I hope you are having as much fun as I have with manual focus lenses.
