Revision as of 13:53, 24 December 2008
The Pearl IV is a 4.5×6cm folder, released by Konica (the later Konica) in December 1958. It succeeded the Pearl III, and was the last of a long line of cameras called "Pearl", inaugurated in 1909. (Other articles deal with the early Pearl for plates and rollfilm, the Pearl No.2, the self-erecting 6×9 Pearl, the Semi Pearl, the Pearl (I), II and III, and the Baby Pearl and Pearlette cameras.)
The camera is a radical redesign of the Pearl III, with a completely different diecast aluminium body and a finder of advanced design with a projected frameline. The finder has additional lines for parallax but there is no automatic parallax correction: the frame does not move when focusing.[1]
The door over the bellows is hinged on the right hand side (as experienced by a photographer holding the camera horizontally), as opposed to all the earlier models; the shutter release is still at the top of the door and near the hinge, it is thus pressed by the right hand whereas the earlier models had a left-handed release button. The diecast body pushes the weight over 700g. The housing for the finders extends almost the whole way across the top, and the accessory shoe is no longer next to it but instead above its centre. The Hexar lens and Seikosha-MXL shutter are inherited from the Pearl IIIL, but the focusing aid is no longer convex but instead a simple tab. There is double exposure prevention as well as auto-stop film advance and an auto-reset exposure counter.
At ¥22,000, the IV was slightly cheaper than the IIIL (¥24,800). However, interest in folding cameras was waning fast, and production of this camera stopped after about six months and after only about five thousand had been made.[2]
The Pearl IV is now regarded as one of the finest cameras of this format. Konishiroku would never again attempt anything like it (or reuse the name "Pearl"). The closest thing to a successor is probably the Fujica GS645 of 1983.
The Pearl IV is often referred to as a rarity. This is an exaggeration: five thousand is not so few, and it is not the kind of device that even the ignorant will unhesitatingly throw into the trash. Examples are not particularly hard to find in the Japanese market; however, they are expensive by folder standards, now (2006) costing around three times as much as examples of the Pearl III in similar condition.
Konishiroku's next medium-format rangefinder would be the Koni-Omega Rapid of 1964; Konishiroku also made an abortive attempt at another 4.5×6 camera with the Konica SF SLR.
Notes
- ↑ The finder is sometimes described as having a frameline whose position adjusts to compensate for parallax. This is untrue: hold the camera steady, focus from the closest distance to infinity, and the view is unchanged and the frameline stays where it was. The frameline does have extra lines to indicate the variation caused by parallax: in this it is similar to some of the better accessory viewfinders (for 35mm rangefinder cameras, etc.) that lack an adjustment for distance.
