Contax 90mm f/2.8 Zeiss Sonnar T* Lens for G-Series, Black {46}

Contax G 90mm f/2.8 Zeiss Sonnar T*: portrait-length sharpness from a rangefinder legend.

The 90mm focal length sits in the sweet spot for portraiture and compressed street work, and the Zeiss Sonnar T* optical formula behind this lens has a reputation for rendering that film photographers spent decades chasing. At f/2.8, you get enough subject separation for head-and-shoulders work while keeping the lens compact enough to suit the G-series body's philosophy. The 46mm filter thread keeps the front element small and accessory costs reasonable.

This is a Contax G-mount lens, which means it was built for the autofocus G1 and G2 rangefinder bodies. The G-system remains a specific commitment: you're working within a closed ecosystem with a finite body of glass, and this 90mm is widely considered the short telephoto to own within that system. Photographers who have already invested in the G platform, or those arriving from the film revival crowd, will recognize immediately what the Sonnar T* coating delivers in terms of contrast and flare control. At this focal length, on 35mm film, the math is straightforward: close-focusing portraits, moderate telephoto compression, and a glass pedigree that holds its value precisely because it was never made in large quantities.

Who It's For

Film photographers shooting Contax G1 or G2 bodies will find this lens a natural anchor for portrait sessions and tighter street compositions, where the 90mm field of view gives working distance without bulk. Travel shooters who want a single telephoto companion to a 28mm or 45mm G-series prime will appreciate the compact form factor relative to the focal length. Collectors and shooters drawn to the Zeiss Sonnar T* rendering specifically, than just any f/2.8 telephoto, will recognize this as the definitive long end of the G-mount lineup.

FAQ

What bodies does this 90mm lens work with?

It's a Contax G-mount lens, so it pairs with the G1 and G2 autofocus rangefinder bodies. This is a closed system - the lens won't mount to any other camera.

Is f/2.8 wide enough for shallow depth of field on portraits?

At 90mm on 35mm film, f/2.8 gives you usable subject separation for head-and-shoulders work, though it's not as extreme as you'd get from a faster 50mm. The focal length does the compression work for you.

What does the Zeiss Sonnar T* coating actually do?

The T* multi-coating reduces flare and boosts contrast - it's the same optical formula that film photographers spent decades chasing. You'll see cleaner blacks and better color rendering compared to uncoated glass.

How close can you focus with this lens?

The verified specs don't list the minimum focus distance, so I can't give you exact figures. Check with the body's manual or contact a G-system specialist for that detail.

Why is this lens considered essential for the G-system?

It was never made in large quantities, and the 90mm fills the short telephoto role in a limited lens lineup. Film photographers specifically sought this focal length for portraits and compressed street work, which kept demand high and supply tight.

What size filters does it take?

46mm - small enough to keep accessory costs down and the front element compact, fitting the G-series philosophy.

Is this lens autofocus or manual focus?

It's autofocus, paired with the G1 or G2 body's rangefinder AF system. The lens itself has no focus ring - focusing is handled entirely by the camera.
