Lately I'm having fun exploring the 'classic glass' characteristics of older manual lenses. I prefer to use them on my X-E3 as these lenses perfectly match and balance with the rangefinder body style.
Introduced in 1957, the Canon 50mm f/1.4 LTM is a ‘classic fast fifty’, aka 'The Japanese Summilux'. It's sharp, it has character, it has nice and smooth bokeh and it's built from all metal and glass. And it looks so amazing! Not that strong as on the Helios 44M-4, but the Canon also shows a little bit of ‘swirly bokeh’ which I like.
Classic lenses are not cheap, I found a type 2 in mint condition from Japan on eBay for $349. For sure good value for this gorgeous piece of gear! As it has the Leica 39mm screw mount, I bought the Fotodiox M39 to FX adapter to use it on my Fujifilm X-E3. The 50mm focus length on a Fujifilm X body turns into a 75mm equivalent.
