As a boy, I grew up in the shadow of The Eastman Kodak Company. Photography was always an interest, from the first time my father and I developed film and printed it in our basement darkroom. After completing university with a business degree, I pursued commercial photography for over 20 years, during film's heydey.

The just-released Sigma 24mm f/3.5 DG DN is the newest member of the L-Mount Alliance. It joins their 35mm and 65mm DG DN compact prime lenses and the older 45mm DG DN (previously reviewed here). Besides the new Sigma 24mm, I happen to own the Leica Elmar-M 24mm f/3.8 ASPH lens and both the Leica SL (601) and Leica CL bodies (both 24MP).

However, when it rolled-out here in the US, it was not compatible with my mobile phone carrier, so I quickly moved it to the back of my mind. Well, those clever marketers at B&H Photo in NYC kept reminding me that I once had an interest in it, so I recently acquired one for $119 USD. For that kind of money I just had to try it!

Metering for Film, Understanding the Basics of Exposure – By JK Lockwood

Shooting film is a challenging process for many new photographers, especially those used to the instant feedback of digital cameras. Modern DSLRs are precision instruments that quite scientifically gather light. Film however is a bit more mysterious. The complete lack of feedback from film, plus multiple film stocks (which all respond differently to light) only adds to the complexity.
