The Sony 55mm 1.8 Zeiss clocks in around a whopping 1000$ new. If you’re lucky and can wait for a great opportunity, you can find it selling for around 600$ – 800$ used on Facebook marketplace or offer up, just be sure to inspect the lens first. I purchased mine for 600 and it was in perfect condition.
What are you paying for?
The reason this lens is so pricey is simple, in a lot of cases you get what you pay for, this is one of those times. While this lens might not be needed for everyone, those working professionally will appreciate the extreme sharpness and build quality of this lens.

A lens around the 50mm focal range is needed in all camera bags, its the most versatile lens a photographer can own. So, if you could only afford one professional lens, it would make sense to go with the 55mm Zeiss; especially if you’re working professionally.
How’s the low light?
The 55mm 1.8 Zeiss holds up nicely in low light as you expect given its stats. Personally this is one of my favorite lenses for low light shooting and street photography. Previously, the 85mm 1.8 from Sony was my most cherished lens and it still holds a place in my heart for portrait work but recently i have had the 55mm stuck to my a7iii.

55mm 1.8 or the 50mm 1.8?
The big question for most of you is will it be worth it choosing the 55mm over the 50mm, the honest answer is no. Most people can not handle this much power, i mean um, sharpness. If you’re focused on videography the smarter choice would be the 50mm. My photographers will have to weigh out the options.
Are you a hobbyist? Do you want to have at least one high quality lens? Do you work professionally for clients? Do you need a competitive edge?
For most, you will not need this lens. I suggest you rent and try this lens out and decide if you actually need it, if you do head over to the My Gear page and purchase it using my link if you’d like, be sure to check offer up and other used local places first though, we’re all about saving money here.
