The Heag II cameras are prepared for ground glass focusing but have also a metre scale for the focusing position of the lens panel. So it is possible to try snapshots without groundglass procedure in good light situations. The lens panel holder is mounted on a slide that can be pulled and pushed forward and backward on the rails of the folding bed. The slide's grip is also the unlocking facility to unlock the slide from its actual position. The lens panel's immediate focusing after pulling it along the rails into operating position is infinity. The lever which locks the slide at that position can be moved aside so that focusing smaller distances by further expanding the bellows becomes possible. A scale helps to find focusing positions for 2 metres to infinity. For near object photography further bellows extension is possible. Therefore the rails can be shifted forward with help of a knurl. That allows lens panel positions at the end of the folding bed (Ser. I) or even beyond (Ser. II). This makes the cameras versatile enough for macro photography or usage of other lenses. Further versatily is given by the facilities for upward movements and sidewards movements of the lens panel. The Series I camera offers additional comfort since its lens/shutter unit is turnable. The cameras don't need shutter cocking for speeds upto 1/100 sec..

The Heag II folding plate cameras belonged to Ernemann's products for ambitious amateurs. The name "Heag" was an abbreviation of the company's name Heinrich Ernemann Aktien-Gesellschaft and was used for a broad variety of folding camera types, numbered I, II, III, IV, etc., the different sizes distinguished by the series numbers I, II, III or other numbers.

The Heag II cameras are prepared for ground glass focusing but have also a metre scale for the focusing position of the lens panel. So it is possible to try snapshots without groundglass procedure in good light situations. The lens panel holder is mounted on a slide that can be pulled and pushed forward and backward on the rails of the folding bed. The slide's grip is also the unlocking facility to unlock the slide from its actual position. The lens panel's immediate focusing after pulling it along the rails into operating position is infinity. The lever which locks the slide at that position can be moved aside so that focusing smaller distances by further expanding the bellows becomes possible. A scale helps to find focusing positions for 2 metres to infinity. For near object photography further bellows extension is possible. Therefore the rails can be shifted forward with help of a knurl. That allows lens panel positions at the end of the folding bed (Ser. I) or even beyond (Ser. II). This makes the cameras versatile enough for macro photography or usage of other lenses. Further versatily is given by the facilities for upward movements and sidewards movements of the lens panel. The Series I camera offers additional comfort since its lens/shutter unit is turnable. The cameras don't need shutter cocking for speeds upto 1/100 sec..

The older variant had the advantage of an additional Newton type viewfinder. The early vertical variant allowed no horizontal lens movements. The early vertical variant had a special spiral gear for focusing.
