Contax g2 digital back manual#
If the camera fails to find focus in this mode, the shutter cannot be released.Ĭomparison of selected parameters, Contax G1 and G2Īperture priority, Manual, TTL flash, Manual flash The G2 auto-focus also has two focusing modes: continuous, which constantly adjusts focus as the camera is moved and single, which is a safety mode, focussing as the focus button is pressed (or shutter release half-pressed), and maintaining this reading until the shutter is released. Ī new active auto-focus system has been added to the G2, which uses near-infrared beams to set the range. In addition, the G2 was made available in a black finish along with black versions of the TLA200 flash and 28 mm, 45 mm, and 90 mm lenses. The manual focus wheel was moved from the top deck to the front, to about the same position as where the focusing wheel was located on classic Dresden and Stuttgart Contax rangefinders. The focus dial on the G1 is the dial marked with distances on the far right side of the body, and is also used to select the autofocus mode on the G2, the focus dial was separated from the focus mode control and moved to the top front edge of the body.Ĭompared with the original G1, the G2 has improved autofocus performance and higher top shutter speeds of 1⁄ 4000 sec in manual mode and 1⁄ 6000 sec in aperture priority mode. While there is an electronic connection between camera and lens to transmit data, the lenses have no AF motor and no means to adjust focus on the lens itself both autofocus and manual focus are driven by a motor in the camera through a mechanical "screwdriver" coupling. The viewfinder uses molded aspherical lens elements to reduce size. The in-body finder shows 90% of the captured frame at 0.59× magnification when the "normal" 45 mm lens is used. The viewfinder covers the field of view for lenses of focal lengths between 28 and 90 mm through an optical zoom, and automatically compensates for parallax error and field when focusing closer. However, the AF mechanism in the G-series does indeed use a twin-window system much like that of the older mechanical rangefinders - only in electronic form. Ĭritics were quick to accuse the G1 of not being a "true" (mechanical) rangefinder, since it used autofocus and electronically linked mechanisms.
The Contax G2 listed for US$2,250 (equivalent to $3,500 in 2020) with the 45 mm Planar lens in 1999.
The 45 mm Planar was listed separately at US$420 (equivalent to $710 in 2020). When tested in 1995, the Contax G1 cost US$2,210 (equivalent to $3,800 in 2020) with the 45 mm Planar lens the 28 mm Biogon and 90 mm Sonnar lenses were each US$660 (equivalent to $1,120 in 2020), and the list price for the 16 mm Hologon was US$3,000 (equivalent to $5,100 in 2020). The two G-series cameras have titanium-clad bodies and use the Contax G-mount, an electronic autofocus mount.
