The TT Signature lens is a single-element meniscus design by Tri Tran that has a custom-turned barrel system that allows you to exchange elements from 9″ to 30″ in the same barrel. 

Literally, one lens barrel with various single elements is all you need as you can see from the photos below.

The unique optical characteristics of this lens are what sets it apart from other soft focus lenses. This lens has an even soft focus glow across the entire focal plane, and the contrast with this lens is unlike any other ULF soft focus lens I am aware of.

I consider this lens and its various elements that I use from 4×5 to 16×20 as my secret weapon for creating ethereal Pictorialist style handmade prints.

With the ability to control the degree of soft focus effect with the integrated aperture control, I can create images that range from dreamlike to slightly soft and emotional.

There is no other lens ever made that offers the ability to use a single lens barrel with variable aperture that accepts lens elements that will cover from 4×5 to 20×24.

I currently own the 9″, 10.5″, 18″, 24″, and 30″ elements. You can check out my YouTube review of this lens.

If you are a photographer or interested in learning about analog photography, I have an Analog Photography Membership Community that is the only community of its kind where you can learn and explore analog photography in depth. I also have an extensive training library of video workshops and guidebooks if you prefer to download the videos and books for offline use.
