This ad-free website's biggest source of support is when you use those or any of these links to approved sources when you get anything, regardless of the country in which you live. Sony and Zeiss do not seal any of their boxes, so never buy at retail or any source not on my personally approved list since you'll have no way of knowing if you're missing accessories, getting a defective, dropped, damaged or used lens, a customer return or if the warranty has already been registered to someone else online! The approved sources I use ship from secure, remote automated warehouses where salespeople or other customers never, ever get to touch your lens before you do, and they have the best prices, selection, service and return policies.

The Sony Zeiss Sonnar T✻ 24mm f/1.8 is the world's best normal lens for Sony's APS-C NEX cameras like the A6000.

This lens excels because of its perfect normal focal length (equivalent to 39mm on a full-frame 35mm camera), great speed, super-close focussing, great sharpness and superb bokeh. Its bokeh is always soft and smooth, easily superior to the bokeh of the $4,500 LEICA SUMMILUX-M 35mm f/1.4 ASPH FLE.

It's so sharp and its out-of-focus backgrounds (bokeh) so soft that sharp subjects pop out from their backgrounds, making photos three-dimensional.

It has an electronic manual focus ring, that if activated in a camera's menu system, can allow manual focus.

 

Compatibility & Format

Top   Sample Images   Intro   Compatibility & Format

Specs   Performance   Recommendations   More

It only works on Sony's NEX series of mirrorless cameras, which are all their mirrorless cameras like the A6000 and A7 series like the A7R Mk II.

It's only an APS-C, not full-frame, lens.

While ideal on an APS-C camera, it's also wonderful on any of Sony's full-frame NEX cameras like the A7, A7R II and A7S II, which automatically self-crop and use the APS-C central parts of their sensors. The only silliness here is that you're wasting half the camera, but you are using all of the lens.

It does not work on DSLRs and DSLR-style cameras like the A99.

Overall

The Sony Zeiss 24mm f/1.8 is the only native choice for a fast wide-normal lens for Sony's NEX full-frame system, and it's excellent.

 

Focus

Autofocus

Autofocus is fast and accurate, no worries here.

 

Manual Focus

It focuses by wire, and since autofocus is so great, I don't know why I'd use manual focus for anything other than to keep the focus locked.

 

Bokeh

Bokeh is superb. It's one of the main reasons to spend $1,100 on this lens.

It's so sharp, and backgrounds are so smooth, that it makes photos look three dimensional when a sharp subject pops against a soft background.

Ergonomics

Sony Zeiss 24mm f/1.8 E

Sony Zeiss Sonnar T✻ 24mm f/1.8. bigger.

It feels like a thin metal vanity shell over a plastic lens.

Ergonomics are easy: the back half of the lens is an easy grab for mounting, and the front half is the electronic focus ring.

The dinky focus ring turns well, but it only does something if you set your camera just right.

Manual focus isn't as nice as a real focus ring; presuming you set your memories correctly, turning the ring simple tells the camera's computer how to move the autofocus motors.

 

Falloff

Falloff is completely invisible as shot on the Sony cameras which correct it by default.

It's not a problem even in this extreme case of exaggerating it by shooting a gray field and showing it on a gray background.

You have to go out of your way to turn the camera's compensation OFF to see anything, and even then it's only mild wide-open and goes away a stop down:

Filters, use with

Filters work GREAT. 49mm is much bigger than needed, so I can stack a few normal 49mm filters with no vignetting.

Go ahead and use all your standard rotating grad filters and polarizers; there's certainly no need for expensive thin filters here.

 

Flare & Ghosts

There are no ghosts and no flare — even with a Hoya HD filter on the front.

See samples under Sunstars.

 

Lateral Color Fringes

There are some green/magenta fringes if you turn off the default in-camera correction, but even if you do, it's not that bad.

With the camera at its default corrections, it's not a problem.

This isn't bad, except that lenses this expensive shouldn't have any at all. This is clearly inferior to Canon's 35/1.4 II as shot on a 5DS R, for instance.

 

Macro

Macro gets very close:

Sharpness

Image sharpness depends more on you than your lens, and lens sharpness doesn't mean much to good photographers.

It's the least skilled hobbyists who worry about this and waste the most time blaming fuzzy pictures on their lenses, while real shooters know that few photos ever use all the sharpness of which their lenses are capable due to subject motion and the fact that real subjects are rarely perfectly flat.

This Sony Zeiss 24mm f/1.8 is super-sharp, right out to the corners, even wide open.

We get our money's worth with this lens; sharpness is exemplary.

MTF at f/1.8 at 10 cyc, 20 cyc and 40 cyc/mm. MTF at f/8 at 10 cyc, 20 cyc and 40 cyc/mm.

 

Spherochromatism

This Zeiss has very minor spherochromatism; much less than other similar lenses. For instance, it's much, much better than the Sony Zeiss FE 35mm f/1.4!

Spherochromatism causes slight color fringes on slightly out-of-focus highlights, usually seen as green fringes on backgrounds and magenta fringes on foregrounds. I doubt you'll ever see any with this lens, and if you do, no one recognizes it anyway.

 

Sunstars

There are no sunstars at moderate apertures; they are softer due to the curved blades.

We get pretty good sunstars by f/22:

Image Stabilization

There is no optical image stabilization.

With the sensor-based stabilization in the Sony A7S II, I get good results down to about 1/4 or 1/2.

 

Recommendations

Top   Sample Images   Intro   Compatibility & Format

Specs   Performance   Recommendations   More

This Zeiss 24mm f/1.8 offers near perfect optical and ergonomic performance on the Sony cameras. It's ultra sharp at every aperture, has smooth bokeh that makes images look 3D, focuses fast and super close, it's fast for low-light, and it has the perfect focal length for use on APS-C as the only lens you'd need. Remember, fixed lenses take better pictures.

It's always better to get a great lens regardless of the price; economize on your camera, but never on your lenses.

The very best protective filter is the Hoya multicoated HD3 49mm UV which uses hardened glass and repels dirt and fingerprints, and is also multicoated.

For less money, the B+W 49mm 010 is an excellent filter, as is its multicoated version and the basic multicoated Hoya, but the Hoya HD3 is the toughest and the best.

 

Where to Get Yours

I got mine at Adorama. I'd also get it at Amazon or at B&H.

Don't ever buy an exotic lens like this at a local, retail or chain store since it will have been played with by everyone before you pay full price for it as "new." Sony and Zeiss do not seal their boxes in any way, so never buy at retail or any source not on my personally approved list since you'll have no way of knowing if you're missing accessories, getting a defective, dropped, damaged, demo or otherwise used product, a customer return or if the warranty has already been registered to someone else online. The approved sources I use ship from secure, remote automated warehouses where salespeople or other customers never, ever get to touch your lens before you do, and they have the best prices, selection, service and return policies.

Thanks!

Ken, Mrs. Rockwell, Ryan and Katie.
