Panasonic Lumix DMC-G1 SLR Review

4/3 Lens Mount
Here's the DMC-G1's lens mount system. This is the first model we have seen that uses the Olympus/Panasonic Micro Four Thirds Specification. Because this is a mirror-less system, they have been able to reduce the distance between the mount and the image sensor from 40 mm (Four Thirds System) to approximately 20 mm. This allows for a much smaller body as well as lenses.
For those of you who are concerned with the fact that dust might fall on your image sensor, Panasonic has included a Supersonic Wave Filter Dust Reduction System. This system is designed to prevent dust from adhering to the image sensor by vibrating 50,000 times per second, helping the filter repel dust and other particles.
On top is the focus control switch with options for AFS (Single), AFC (Continuous), and MF (Manual). You can also see the flash pop-up release.
To use some of your existing 4/3 system lenses, Panasonic does offer the DMW-MA1 is a mount adapter. However, continuous autofocus can not be used as well as some other functions. Hopefully, more Micro 4/3 lenses will be released in the near future.
The DMC-G1 comes as a body/lens outfit, which includes the very nice LUMIX G VARIO 14-45mm/F3.5-5.6 ASPH/MEGA O.I.S. lens.
The H-FS045200 45-200mm f4.0~5.6 O.I.S. is a Micro 4/3 telephoto zoom interchangeable lens with OIS and metal mount that can be used with a Panasonic Lumix G Micro System Camera or any Micro 4/3 System Camera.
The built-in flash unit has a Guide Number of 11 (ISO 100, m). This manual pop-up flash has modes for Auto, Auto/Red-eye Reduction, Forced On, Forced On/Red-eye Reduction, Slow Sync., Slow Sync./Red-eye Reduction, and Forced Off. You can shoot at synchronized speeds up to 1/160 second.
The 'hot shoe' allows you to extend the effective flash rage with an optional external flash unit, like Panasonic's DMW-FL500 (shown below).
The DMW-FL500 offers a motorized zoom head and powerful AF-assist beam. This dedicated flash unit has a guide number of 50, with a angle zoom function which covers a lens range of 24-85mm (35mm camera equivalent). Using the built-in wide panel further extends coverage to a viewing angle of 18mm. The firing angle can also be automatically changed to create a bounce lighting effect.
Much like several prosumer and super-zoom models, the G1 offers an electronic viewfinder or 'LVF' (Live View Finder). This is a tiny high-resolution LCD in a magnified eye piece (1.4x) that offers 1.4 million dots. Unlike optical viewfinders, this unit provides 100% field of view coverage, a 17.5mm eye point, comfortable rubber eye cup, and -4.0 ~ +4.0 diopter adjustment. To the right of the LVF is a sensor that turns this display on when you put your eye up to it.
To the left you can see the LVF/LCD button to switch between monitors, and on the right is the Play and AF/AE Lock buttons.
