Version 2 is released with vastly improved perspective compression.
Now works best up to 1.0 strength.

I'm a pro photographer and programmer of 20 years and I've used a lot of lenses. I love using AI models but the lack of real lens control frustrates me. To that end I'm releasing my first lens lora. If people want more I'll make more. It is best used at .50 strength , with the tag 600mm in your prompt. this first release is for Z-image Turbo, but if there is interest I'll make it for WAN also. I've a huge photo archive to train on with dozens of lens over the years, but I'm also open to training specific lenses if provided the necessary samples to train with if needed.

To attain a full 600mm vibe, promoting for full length for a person can help greatly, especially if using a vertical image, in this scenario you will get a full on 600mm perspective very regularly. Equally so for shots that often have long lenses associated.
For shots where a 600mm is rarely used its harder and you may end up with something more like a 150mm etc, but can be done, just work on the prompt to push it more to the 600mm look.
