Hello folks,

I'm about to get the SD1 Merrill for portrait work only and I was wondering about which lenses I should get for it.

Not necessarily Sigma ones!

I have a Canon 5dII setup (if interested see my gear list) which will take the back up role now but I can't decide between the 30 1.4 or 50 1.4 for my first lens with it. I really want a "normal" lens first off but I've been seeing conflicting reviews on the net for the 30 1.4. Some tests show it is great and some show it's kinda "meh". What are you guys using for a "standard lens"?

Something like a 28mm equivalent on FF? I'm definitely gonna get the 50 1.4. Are there any good wides available?

Depends what you call a standard/normal lens on 1.5x crop...My Carl Zeiss 28mm f2.8 Distagon T* is about 48mm equivalent on my SD14, pretty close to a classic 50mm normal but on the SD1/SD1M its only 42mm equivalent..An odd focal length.

A Sigma 30mm would give 51mm equivalent on my SD14, extremely close to a 50mm normal but on the SD1/SD1M it becomes 45mm equivalent, another odd focal length.

A 35mm lens like my Nikon 35mm f1.4 Ai-S is about 60mm equivalent on my SD14 but on the SD1/SD1M its about 53mm equivalent, pretty close to a 50mm normal.

So you should really give 28mm and 30mm lenses a wide berth with the SD1/SD1M, if you want a 50mm normal FOV.

To get a FOV equivalent to a classic 28mm wide angle you will need to look for a 19mm prime...The Leica 19mm f2.8 Elmarit R being a very good example.

A 16mm will be exactly equivalent to a classic 24mm wide angle, unfortunately, 16mm primes are very few and far between, and the few 16mm lenses that are available are usually fish-eye lenses, like the Zenitar 16mm f2.8 fish-eye.

The widest rectalinear prime lens options are the Sigma 14mm f3.5 or the 14mm f2.8 EX, both giving 21mm equivalent on the SD1/SD1M.

You can only go wider, and stay rectalinear, if you get the Sigma 8-16mm EX or one of the 2 versions of the Sigma 10-20mm EX.
