Before things get too hot here in the northern hemisphere, Fuji will debut cool firmware for their X-Pro 1 and X-E1 cameras. Several of the improvements may be worth the wait.

FUJIFILM X-Pro1 Ver.3.00, FUJIFILM X-E1 Ver.2.00

1. Improvement of AF speed. Improves AF speed on all existing XF lenses, thanks to the updated algorithm throughout the full range of focal length. Lenses covered:

XF14mm F2.8 R

XF18mmF2 R

XF35mmF1.4 R

XF60mmF2.4 R Macro

XF18-55mmF2.8-4 R LM OIS

NOTES:

The AF Speed on the XF55-200mmF3.5-4.8 R MS OIS lens has been already optimised.

For all lenses other than the XF55-200mmF3.5-4.8 R MS OIS, the firmware for each lens must be also updated.

2. ‘Focus Peak Highlight’ function for manual focusing

A ‘Focus Peak Highlight’ function, which features on the X100S and X20 cameras, can be added via this firmware update. It assists accurate and sensitive manual focusing by enhancing the outline of your subject in high contrast.

3. Improvement in ‘Checking Focus’ operation: how to change magnification ratio in manual focusing

The process to check focus by selecting manual focus magnification has improved. Just press and rotate the dial right or left and the camera will alternate magnification between 3x and then 10x , whichever way you continue to turn it.

In related, and almost equally exciting news, DPReview reader, David McGaughey, unearthed a much-skipped feature of the new X-M1 camera. That feature is minimum shutter speed in auto ISO. If you're shrugging a "so what?" into your computer screen, you probably don't shoot Fuji's X series of interchangeable lens cameras.

The lack of minimum shutter speed setting in auto ISO has been the most vociferous detractor's cry since the first X cameras got into public hands. Pshaaawh! Flickr users, wedding togs, and X-Forum geeks certainly carry more weight than us former rangefinder camera users.

Our biggest complaint: no manual focus check capability from the OVF- ignored by even the least tractored among Fuji's growing fan base.

Well, if David is right (and I know he hopes so), the nifty feature on page 4 of the X-M1 press page, will change the lives of a large number of X owners.

Go minimum shutter speed in auto ISO!
