The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica TL 35mm F1.4 ASPH and the Leica Summicron-M 28mm f2 ASPH for their suitability to various photography scenarios:
Size and Weight Comparison
The size of a lens is a crucial factor to consider when comparing two lenses. Leica TL 35mm F1.4 ASPH is the longer of the two lenses at 77mm. The Leica Summicron-M 28mm f2 ASPH with a length of 41mm, is 36mm shorter. Besides being longer, the Leica TL 35mm F1.4 ASPH also has a larger diameter of 70mm compared to the Leica Summicron-M 28mm f2 ASPH's 53mm diameter.
The weight of a lens is equally significant as its external dimensions, particularly if you intend to handhold your camera and lens combination for extended periods. Leica TL 35mm F1.4 ASPH weighs 128g, which means it is 142g (52%) lighter than the Leica Summicron-M 28mm f2 ASPH which has a weight of 270g.
Filter Threads
The Leica TL 35mm F1.4 ASPH has a filter size of 60mm whereas the Leica Summicron-M 28mm f2 ASPH has a 46mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 60mm filters that we recommend you to consider for the Leica TL 35mm F1.4 ASPH:
And these are the 46mm filters that we recommend for the Leica Summicron-M 28mm f2 ASPH:
Lens Mounts
The Leica TL 35mm F1.4 ASPH has the Leica TL lens mount whereas the Leica Summicron-M 28mm f2 ASPH has the Leica M lens mount. Some of the latest released cameras that are compatible with these mounts are , and for the Leica TL Mount and Leica M11 Monochrome, Leica M11 and Leica M10 for the Leica M Mount.
Focal Range
Leica TL 35mm F1.4 ASPH is a prime lens with fixed focal lenght of 35mm which has an effective (full-frame 35mm equivalent) focal range of
52.5mm when used on a APS-C / DX format camera.
On the other hand, the Leica Summicron-M 28mm f2 ASPH is a prime lens with fixed focal lenght of 28mm.
