2.) To be optimally used this tripod head against it for compact cameras and flash units of all kinds etc. 'ie in a weight range of up to about 500 g. For precisely this application I purchased this tripod head. The workmanship is very good, fasteners are made of only metal. High diversity of connection options: System hotshoe or 3/8 "- or 1/4" -Systemstativanschluss. In addition, the tripod head can be tilted at a point at 90 ° in order to realize for example portrait shooting. And for the last 2. Application is appeal for this tripod head a strong buy recommendations with 5 stars.
3.) On customer request (24.06.2015): The hot shoe mount (silver) is made entirely of metal probably aluminum, and the outer locking screw. The screw for locking the ball head is made of steel and is covered on the outside with resistant plastic. The vendors (Photecs) speaks in his offer of a carrying capacity of up to 2 kg. As a permanent load these 2 kg seem to me, however, clearly too much, especially when the load (Photo accessory) is not fastened vertically or horizontally on this ball head.
4) The delivery from the order task (in the evening) in only 1 'days by PHOTECS (standard delivery). This is well below my average observed at amazon. Sometimes a standard delivery may take about 4 '7 days at amazon. So if you urgently need a product, then you have just purchased via Express or select a different mail order. But what counts is the quality and range of applications of a product and not the delivery time. The delivery time does not flow into my review.
