The Premista 28-100mm (shown below) has a consistence speed of  T2.9 throughout the zoom range, but FUJINON says the 80-250mm stays at T2.9 until about 200mm and then slowly ramps to T3.5. While a constant aperture would certainly be preferred, the wide range of 80-250mm is a bonus. Consistent with past FUJINON zooms, both lenses will be available in PL mount. In the past, companies like Duclos Lenses have converted PL FUJINON zooms to an EF mount, so that may be possible again here in the future.

FUJINON lists both lenses as supporting up-to a 46.3mm image circle (diagonal) without vignetting. This covers all current large format digital cameras such as the RED Monstro with the exception of the ARRI Alexa 65 (54.12 mm x 25.58).
