Having had a few micro four third lenses over the past few years and been asked what is your all time best lens, I could not answer this question till now.

The answer has to be the 12-100 f4 Olympus PRO lens which gives stunning optical performance and the best news for GH5S owners is it also comes with image stabilisation (IS) built into the lens.

I bought this lens specifically for my documentary on Arran in July this year as I wanted a lens that would sit on the camera without the need to keep transferring from one focal length to another, this helps the sensor, keeping dust to a minimum.

This is a cracking lens for any micro four third mount camera and converting it to an equivelant 35mm its a 24-200mm constant f4 lens.

• Professional 8.3x travel zoom lens
• Constant 1:4.0 aperture
• Dust-, splash- and freezeproof
• 1.5cm minimum working distance for extreme close-up performance
• Combines up to 6.5 EV steps** compensation when used with compatible Olympus camera and built-in 5-axis Sync IS
• Z Coating Nano to significantly reduce flaring
• High-precision, very fast AF
• L-Fn button and focus clutch
• Weight: only 561g

The JVC LS300 has been missing a good all round zoom lens and onto the super 35mm sensor this 12-100 f4 Olympus PRO lens is perfect. Please remember the JVC LS300 has a super 35mm sensor with a micro four third mount and you use the VSM (Variable scan mapping) to adjust for the MFT lens.

Using the lens with the LS300 you get all autofocus and image stabilisation functions, though the great design of this lens lets you quickly move from AF to manual focus at the touch of the front lens flange by pulling it back.

Its also not very front heavy as I was first expecting and remember you also get the ability to zoom into the 4K sensor using the camera in HD mode as if you had a servo zoom, great feature with no loss in picture quality or “f” stops.
