Photoclub Alpha

My review of the Sony Alpha 550 was supposed to appear at the end of November, allowing one week abroad in good weather with plenty of subject-matter, in Tenerife. Sadly that trip had to be cancelled, and the Nikon D3S arrived for review on the day we were meant to have travelled. So, with far too much work to do on the D3S, I’m “going to press” here with my initial thoughts based on a fairly short time using the Alpha 550. There are 11 pages in this review, please use the Next Page navigation at the end of each page to continue reading.

PLEASE NOTE: this website uses a rating system where readers can rate the posts, like this review. This rating is NOT my ‘rating the camera’! I have read elsewhere that I ‘gave the camera 4.83 out of 5′ – that was the rating readers gave my review… sorry, this is very confusing, I had not realised how easily it could be confused. We have had the post-rating system for a long time and it’s a standard feature on many Wordpress based sites. I do not want to remove it (along with the ratings) so please accept this apology for incorporating a dangerously confusing ’star rating’ here.

Tokyo, Japan, November 10, 2009 — Ricoh Co., Ltd. (president and CEO: Shiro Kondo) today announced the development and release of the GXR interchangeable unit camera system featuring the world’s smallest and lightest* digital camera with the ability to change lenses.

The new GXR is an interchangeable unit camera system in which lenses are changed by using a slide-in mount system to attach camera units to the body. The lens, image sensor, and image processing engine are integrated into the camera units so the body itself does not contain an image sensor.

With world-leading small size and low weight* enabling easy carrying, the GXR interchangeable unit camera system features a highly rigid magnesium alloy body and multiple camera units that can be changed to best fit the scene to be photographed. You can enjoy easy lens changes as well as amazing image quality and shooting flexibility. Concealing infinite possibilities in its small body, the GXR is a revolutionary camera system that pioneers a new realm of photography.

Distinctive characteristics:
1.    Lens, image sensor, and image processing engine comprise an integrated unit which can be changed to match the scene being photographed.
2.    World’s smallest and lightest* digital camera with interchangeable lenses
3.    System potential expanded through use of interchangeable units

Comment from David Kilpatrick:

Though the Ricoh system as revealed through this press release appears to show only a GR-size body with a zoom lens module suitable for a 2/3rds or slightly smaller imaging sensor, Ricoh has said that sensors right up to the size of APS-C will be built in to further lens modules. The ultra-wide angle version would have an APS-C sensor making similar to the Sigma DP-1. For similar reasons, high ISO and fast lens may be combined with a different size of sensor.

This is not the first time a digital camera has been designed with lens-sensor modules that could be changed. The Minolta Dimage EX 1500 accepted either a standard zoom module, or a wide-angle module. These included viewfinders (missing from the Ricoh concept, which relies entirely on the rear screen or electronic viewfinders) and had the unique ability to be removed from the camera on a 1.5m long Cable EX. This allowed users to position the wide-angle module inside scale models, doll’s houses and similar subjects to obtain realistic human-scale perspectives. It was only a 1.5 megapixel camera, and Minolta abandoned the concept before they had a chance to develop it further, whatever dPreview said ten years ago:

The technology behind the Ricoh is not all that different from the way consumer digital cameras are constructed anyway. Lenses are already sold sealed to CCD/CMOS sensors, as a single unit. That is how the OEM sources of the lens-sensor modules market them. At photokina, you can see (every two years) a new crop of such modules with both the technical resolution specs of the optical unit and the megapixel count of the sensor, identifiable to this non-Chinese/Japanese reader in the middle of a description which is usually inb Chinese. In 2006, I tracked such a module from its maker to the first camera I could find which used it – a compact branded as Vivitar. The customisation consisted of building any body the maker chose to design, and putting a ring on the lens front labelling it is a high resolution Vivitar lens; actually, it was just a generic lens-sensor assembly from China.

Ricoh has also pioneered unusual digital designs in the past, including rotatable or detachable lens modules and one of the first viewfinder-less designs, where the viewing screen was intended to be used at waist-level rather than today’s habit of waving the camera in front of your face.

This differs from anything previously done in the power of the CPU unit in each lens module, and the control unit with display and card module in the host body. It should allow any reasonable pixel count and sensor size to be built in to future optical modules. If the accessories do eventually include dedicated APS-C lens-sensor sealed modules, ‘dust on sensor’ will be one clear benefit (or the lack of it will). A supertelephoto module is also planned which will use a sensor smaller than APS-C.

The new Alpha 230, 330 and 380 models are radical ergonomic redesigns of the existing 200, 300 and 350 series. There is a 15% reduction in size (volumetric) and weight, an update to the styling, and a completely revised user interface with graphic representation of setting adjustments – with a built-in ‘handbook’ to accompany the modes and options. They also have mini-HDMI image output, compatible with Bravia TVs and with interactive software inside the camera to allow the Bravia’s own remote control to change, orient and zoom into images (Bravia Sync). Twin card storage is MS ProHG Duo/SD and only one card is usable at a time, with a hardware switch to change slots. A smaller battery type (shared with the HX1 Cyber Shot) is used. A new self-timer drive mode grabs a quick burst of 3 or 5 frames, cutting the chances of spoiled portraits and groups shots when someone blinks at the wrong moment.

The new flashgun HVL-F20AM operates as a wireless flash controller for the full-frame α900. “While Sony’s flagship DSLR does not have its own integrated flash, the HVL-F20AM can be used as an inexpensive trigger for wireless remote flash heads” according to Sony UK.

Tamron Co., Ltd (Mr. Morio Ono, President), a comprehensive manufacturer of optical products with its head office in Saitama City, has announced the development of the SP AF60mm F/2.0 Di II LD (IF) MACRO 1:1 (Model G005), a life-size macro lens designed exclusively for digital SLR cameras with APS-C size image sensors* that offers a fast maximum aperture of F/2.0.

Press release from Sony, March 3rd 2009 – important bits highlighted in bold, uncalled-for comments in italics:

The Cyber-shot HX1 by Sony, teams stunning picture quality, lightning-fast shooting and powerful creative features in a stylish, supremely easy to use camera. The new flagship of the Cyber-shot range showcases a range of sophisticated image sensing, optical and processing technologies that offer unrivalled creative possibilities.

Sony’s new back-illuminated CMOS sensor design makes its first appearance – along with technology borrowed from the Alpha system – in a new HD Handycam video model, the HDR-XR520VE/500VE. Hopefully presaging future DSLR developments, the range also includes models with built-in GPS tracking to record the location of shots as you film.

If you are on the verge of making a decision, I’m here to help your think clearly – even if it means breaking some cherished behaviour patterns. I am going to help you think of the Alpha 900 not as a logical progression from the 700, but as a different camera system entirely.

TEMPORARY Sony website pages on the afternoon (GMT) of September 5th managed to leak the entire specification sheet and several new PR images of the advanced amateur Alpha model, along with its name – the Alpha 700. You wouldn’t pick a wife or husband on the basis of their on-paper specification, so remember, the only way to partner up with a DSLR and be happy is to try it in your hands first.

Weybridge, 22nd August 2007 – For sports, for travel or simply for having fun with friends and family – the Cyber-shot H3 from Sony packs big-camera features into its ultra-compact body at a price that’s irresistible (reads Sony press release).

More work went into this page than you think! While it was possible to get an idea of Sony’s lenses and cameras planned for 2007-8 from the group image, the individual press images have all been shot to different scales.

IN 1998 Minolta published, for their 70th anniversary, a large poster featuring all the landmark cameras from their own museum and employee collections. Many of the cameras shown – all fairly small on the poster – were well used and worn examples. The original image-files for the poster, which we have archived, are of poor quality. They are Japanese inkset CMYK sharpened for pre-press, with very dark gamma. This page re-creates all the information from the original poster, complete with the photographs. This page has been updated so that each period now appears as a separate section – simply select the next page to move on after reading each one. Page 1 is 1928-39, Page 2 1940-1959, Page 3 1960-69, Page 4 1970-79, Page 5 1980-89, and Page 6 is the 1990s. If you know the period of the camera you want to see, go straight to the page.

THE appearance of press-release resolution (14Mb) images of the new Alpha – un-named but thought to be the Alpha 200 or 300 because of the product code earlier assigned to shots of prototypes at PMA – combines with reports on various forums from European Sony executives visiting Japan to suggest that the launch announcement for the new model and a range of full-frame lenses is imminent.

THE NEW Tamron 18-250mm has some importance to Alpha system users. It is almost certainly the optical basis for the forthcoming Sony SAL 18-250mm version, and as a APS-C 13.7X zoom with an equivalent 27-375mm (in full frame terms) range is uniquely suited to the SSS-enabled Dynax 5D, 7D and Sony Alpha 100
