Manual Lenses on the Sony a7/a7II/a7III
Why should I use manual lenses?
- They can be very cheap, you can get a great 1.4/50 lens for $50. For most applications such a lens will give you 90% of the performance of a $1000 Zeiss 1.8/55 FE. For the $1000 you would have to pay for that Zeiss you can buy an excellent set of five lenses from 20 to 300mm.
- You have a huge choice between thousands of lenses ranging from exotic ones with lots of “character” to some of the very best lenses available.
- There are 30-year-old primes with better image quality than many modern lenses. Of course progress has happened in recent years but still affordable primes are often sharper than very expensive modern zooms.
- Old lenses are usually beautifully built from nothing but metal and glass which makes it a joy to handle them. They can last a lot longer than modern lenses which are full of electronics and very complex designs, both of which make them more likely to fail.
- They also hold their value much better than modern lenses. With some patience you can sell most manual lenses without a loss but with new lenses you can expect to lose 30% in the first year.
- Manual focusing can be very enjoyable. This certainly depends on application but personally I enjoy working with fully manual lenses a lot more than with any AF lens and I would choose a good manual focus lens over an AF lens (almost) any time.
