Minolta DiMAGE 5 Review
A very similar performance to the DiMAGE 7, fairly good flash metering if a little bright on occasions (you can adjust the flash power output through the record menu). The DiMAGE 5's flash unit has a rated range of; at wide angle: 0.5 - 3.8 m (1.6 - 12.5 ft), telephoto: 0.5 - 3 m (1.6 - 9.8 ft).

The DiMAGE 5 allows a maximum exposure of 4 seconds in manual exposure mode, this can be extended to up to 60 seconds in Bulb mode, but of course that means holding the shutter release button down without wobbling the camera. The DiMAGE 5 does seem to be capable of exposures at least up to 16 seconds, I really don't know why Minolta didn't include them. Add a simple dark frame subtraction routine and you'd have fairly nice noiseless night shots straight from the camera.

Barrel and Pincushion Distortion
The DiMAGE 7 faired well, considering you were getting 28 mm equiv. However, 1.3% distortion at wide angle at 35 mm will be noticeable. That said telephoto pincushion distortion is a very respectable 0.5%, considering it's the equivalent of 250 mm on a 35 mm camera.
|Barrel Distortion, 1.3% @ Wide Angle||Pincushion Distortion, 0.5% @ Full Tele|
Purple Fringing (Chromatic Aberrations)
We noted in our review of the DiMAGE 7 that this lens exhibited very few chromatic aberrations, and of course the same applies to the DiMAGE 5. For a lens with this much focal length range (zoom) it performed very well, I had to hunt through our collection of sample images to find an example of chromatic aberrations in a 'every day' shot.

Overall Image Quality / Specific Issues
On the whole (working around the camera's caveats) the DiMAGE 5 worked fairly well. Colour balance was on the whole good (after being run through the Image Viewer application), as was its tonal (grayscale) balance and usable dynamic range. Resolution was around the average (or a little less) for a three megapixel, which is a shame because I'm convinced that this is not a problem with the lens. Metering tended to be a little too center weighted so judicious use of exposure compensation (normally negative EV) would sometimes be required.
Samples below are straight from the camera and HAVE NOT been run through the Minolta Image Viewer application.
Just like the DiMAGE 7 and to a certain degree the DiMAGE S304 the DiMAGE 5's AF system wasn't the best, quickest or most accurate I've ever used. On several occasions the camera would insist it had a good AF lock (showing a solid black dot on the LCD monitor) which later turns out to be a bad AF. Examples below are crops from a larger image.
Flat Area / Shadow Noise
Unfortunately the DiMAGE 5 turned out to be a fairly 'noisy' performer, for well exposed 'bright' image areas the detail (signal) generally outweighed the noise and so wasn't as visible, but delve into the shadows or look at an area of blue sky and you'll soon see more noise than I would like (or expect) of a three megapixel prosumer digital camera (certainly at this price point). Below are three 100% crops from the image shown in the first thumbnail.

Fujifilm has announced its GFX 50R, a rangefinder-styled version of the company's GFX 50S medium-format camera. The 'guts' of the two cameras are the same, with the difference being the design, weight and Bluetooth, all at a considerably lower price.
In this episode of DPReview TV, we get our hands on Fujifilm's GFX 50R which hides a medium-format sensor in a new, more compact body. Watch to get Chris and Jordan's first impressions on image quality, video and more.
Fujifilm is adding a trio of new medium-format lenses to its G-mount roadmap. GFX owners will soon be able to get their hands on 100-200mm F5.6, 45-100mm F4 and compact 50mm F3.5 lenses. Pricing and availability have not been announced.
Micro Four Thirds users will soon get a super fast, constant aperture wide angle zoom.
Panasonic has announced it is developing two full frame mirrorless cameras: the 47MP S1R and the 24MP S1. We've been shown fairly advanced-looking but non-functional prototype cameras, and have been able to squeeze a few details from Panasonic.
Panasonic is developing a pair of full-frame mirrorless cameras that use Leica's L-mount. The S1R will feature a 47MP sensor, while the S1 will be 24MP. Both cameras will support Dual IS shake reduction 4K/60p video capture and will have XQD and SD card slots.
Leica, Panasonic and Sigma are teaming up. Expect L-mount cameras from Panasonic as well as L-mount glass from Sigma.
