Canon EOS 1NHS

Marketed November 1994

I'd always hankered after an EOS 1n and eventually took the plunge and bought a 1nHS. I love the weight and feel of this camera, even when loaded up with a L lens and flash. It feels very solid and reliable. After we sold the two websites and I'd moved to digital I didn't have much need for it and I did try to sell it, but as it wasn't moving at the dealers I gladly took it back and still own it. I now use it for the occasional roll of slide film.

From Wikipedia, the free encyclopedia

The EOS-1N is a 35mm single lens reflex (SLR) camera body produced by Canon. The EOS-1N was announced by Canon in 1994, and was the professional model in the range, superceding the original EOS-1. This camera has now been superceded by the EOS-1V.

The original EOS-1 marked Canon's new entry into the professional autofocus area of camera design and building. They had the F-1 models during their FD-lens period but these, while well resected, never managed to topple Nikon from the top spot. However, following their bold decision to change lens mounts, Canon did manage to convince many professionals to swap to their system with the EOS-1. The EOS-1N model followed on from the original EOS-1, retaining the same design concept but introducing many improvements and honing the design. The original EOS-1 was strongly influenced by the Canon T-90, which was designed by Luigi Colani. This same basic form has been used by Canon in all their professional SLR and many DSLR cameras.

One feature the EOS-1N (and previous/subsequent '1' models) lacks which does feature in lower models in the range is built-in flash, presumably omitted on the basis that professionals did not want such a 'gimmick', although it may also have to do with weather sealing, which is a feature of the EOS-1N. Other examples of this are the eye-control feature of the EOS 5 and the bar code reader of the EOS 10, neither of which appeared in the '1' models.

Another feature of the EOS-1N, and other models in the range, is the provision for a proper viewfinder indication of exposure in manual mode. This had previously been provided in fully manual cameras such as the F-1, but older Canons with automatic exposure modes merely provided a recommended exposure reading in manual mode, leaving the user to make the offered settings or not as they saw fit. The EOS-1N provides a viewfinder readout similar to the old F-1's needle display, but in electronic LCD form.

The optional Power Booster Drive E1 or Battery Pack BP-E1 attach to the bottom of the camera. The booster (PB-E1) holds more batteries and has a Ni-Cad option, and provides more power to run the wind-on faster giving a greater frames-per-second rate. It also has an extra shutter release and input dial for use when shooting in upright format. The battery pack (BP-E1) is a somewhat simpler device. It holds 4 AA cells and a lithium battery, and you can select one or the other with a switch. It provides a grip for vetical shots but no extra controls. It is lighter and less expensive than the booster.

The 1N was the successor to the EOS-1 and was then the new top-of-the-line EOS camera. It was later superseded in 2001 by the Canon 1V.

The camera works well with the longer telephoto lenses as the weight of it, especially with the attached booster, makes if feel more balances and less front heavy.

The INHS is basically an EOS-1N with Power Drive Booster E1 attached. This also provides power for the camera as the booster holds 8 AA batteries and enables it to operate in high speed wind mode at 5 frames per second.
