The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Leica 60mm f2.8 ASPH and the Leica APO 75mm 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 60mm f2.8 ASPH is the longer of the two lenses at 89mm. The Leica APO 75mm f2 ASPH with a length of 67mm, is 22mm shorter. Besides being longer, the Leica 60mm f2.8 ASPH also has a larger diameter of 68mm compared to the Leica APO 75mm f2 ASPH's 58mm 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 60mm f2.8 ASPH weighs 320g, which means it is 110g (25%) lighter than the Leica APO 75mm f2 ASPH which has a weight of 430g.
Filter Threads
The Leica 60mm f2.8 ASPH has a filter size of 60mm whereas the Leica APO 75mm f2 ASPH has a 49mm 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 60mm f2.8 ASPH:
And these are the 49mm filters that we recommend for the Leica APO 75mm f2 ASPH:
Lens Mounts
The Leica 60mm f2.8 ASPH has the Leica TL lens mount whereas the Leica APO 75mm 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 60mm f2.8 ASPH is a prime lens with fixed focal lenght of 60mm which has an effective (full-frame 35mm equivalent) focal range of
90mm when used on a APS-C / DX format camera.
On the other hand, the Leica APO 75mm f2 ASPH is a prime lens with fixed focal lenght of 75mm.
