* Canon EOS-1N   Basic configuration with option to accept various system accessories.
* Canon EOS-1N DP:   This model combines the BP-E1* AA-size battery pack with the EOS-1N, allowing the user to switch between the standard 2CR5 lithium battery or AA-size batteries depending on the shooting situation.
* Canon EOS-1N HS:   This model combines the Power Drive Booster E1 with the EOS-1N, providing high-speed continuous shooting and increased shooting capacity. The most popular combination among all options.
* Canon EOS-1N RS**:   This model features a nonmoving, hard-coated new pellicle mirror which provides non-interrupted viewing through the viewfinder and rapid-fire continuous shooting at 10 frames/sec. Moreover, the camera’s release time lag (the time between when the shutter button is pressed and when the exposure occurs) is reduced to a mere 0.006 sec. This modified variation of the Canon EOS-1N will be featured separately

What actually are the differences between these models ?

One of the key element in the EOS-1N series was centered around multiple options in permitting the photographers to select the power source. Naturally, each power source in combination with the basic body will deliver variable degree of performance as well. Reliable and high performance power source has become an integrated part of a modern SLR as gone are the days where even a high performance SLR only require button cell(s) to operate. The main factor contribute to such demanding task is the power thirst requirement from servo drive on Autofocusing as well as electronic circuitry internally.

Except for the lack of an option to take AC/DC power source (for an instance, studio fashion and/or product shots etc. which may sometimes be quite demanding and could take hours between assignments). Overall, I would think the various options provided are quite adequate for most and usually, for any important assignments, smart users would think of having back-up packs rather than caught in embarrassing or desperado situations - it is entirely a good personal practice on pre-assignment preparation. Basically, a bare basic Canon EOS-1n has an integrated motor drive ("MD") built-in, meaning you don't have to manually perform film advance each time after an exposure, the MD will, automatically advance to the next frame and ready to fire should you be tripping the shutter release button all the way down again. Naturally, it will also perform power film rewind upon completion of a film roll. One of the advantage of the bare basic camera body is, it is very compact and lightweight - something that where your preference is on mobility or travel light and/or doing some personal photography other than professional assignments. The maximum sustainable auto film advance rate in this case delivers a moderate (professional-class expectation) speed at approx. 3.0* frames per second ("fps") and 2.5 fps in predictive tracking autofocus operation. * Canon official published data. Performance figures based on numerous users feedback suggested 3.5 fps and 3.0 fps respectively.


Canon provides performance or features enhancement with extensions from this basic modular design which has a direct relation with various power sources. The basic configuration of the Canon EOS-1
N uses 2 x CR5 lithium cells which hosted inside the removable hand grip GR-E1handgripsole.JPG


Actually, this electronic beast does not looked particularly very eye-pleasing after being stripped off the skirting...hehe...
battery installation instruction with GR-E1)

The handgrip is not exactly an interchangeable type but rather the alternate power pack in the form of a battery Pack E1 OR Power Drive Booster E1 each has a vertical hand grip in place so as to be able to mount directly onto the empty slot after removing the GR-E1 handgrip.

The Canon Battery Pack BP-E1 looked like conventional motor drive but it is just an accessory for you to use different kind of power sources - mainly switches between four (4) x AA size cells or even lithium. However, it doesn't seemed to improve the film advance rate of the EOS-1N (it doesn't help to boost the camera as in the case of the PDB-E1, note the lack of a motor drive coupling) but it is important as AA alkaline batteries are common throughout the world where in some remote areas, you still can find such power source easily. Basically, you can term this accessory as a battery chamber cum hand grip. One of the unique feature is, the battery pack is, it can simultaneously house a 2CR5 lithium battery (just like the basic EOS-1N) as well as and there is a selector to switch between the alkaline batteries and the lithium battery.

Well, the true capability of the Canon EOS-1N is when the other option of a Power Drive Booster E1 attached to it. In such combination, the EOS-1N can be set to One-shot AF mode and Manual Focus, but the true colors of the EOS-1N show here as it will transform the otherwise so-so performance film advance rate of 3.0 fps* (2.5 fps* in predictive AF tracking) to a blistering shooting speed of about 6 frames per second (fps) and up to 5 frames per second (fps) during predictive AF

<<<-- Canon official published data. Performance figures based on numerous users feedback suggested 3.5 fps and 3 fps respectively.

In addition to this, the Booster Drive E1 can use either eight (8) AA alkaline batteries or eight (8) rechargeable AA Ni-Cd batteries. Also, those Power Drive Booster E1 model that is having an asterisk next to the AE lock button on the vertical grip permit the use of increasingly popular AA lithium batteries. Using these can decrease the equipment's weight by approximately 60g (2 oz). This is essentially why whenever Canon EOS-1N is mentioned, it usually directly associated with the Power Booster Drive E1 because it is not just an accessory to use various power sources, but it is also an independent motor unit unit rather an integrated system component for the camera and the peak film advance rate is simultaneously goes in line with performance of other areas such as AF, film rewind options and overall power efficiency in different operational conditions etc.

That is not all - the overall film winding/rewinding noise level has also significantly reduced as compared to the pervious EOS-1.

Image above: Canon Ni-Cd Battery Pack E-1 can also be used, Canon has a dedicated Ni-Cd Charger E-1 just for this Battery Pack, so the Power Drive Booster E1 has quite a few alternatives.

From here, I guess two questions here may pop up from your mind: First, why wouldn't the Power Pack E1 be able to deliver similar performance as the Booster Drive ? And next, why wasn't it being designed in such a way like the Nikon F5 that followed in 1996 with the Booster Drive made as an integrated unit ? Well, one of the design of the Booster Drive was, making it be able to optimize the power input as well as it will immediately convert the basic EOS-1N camera's 2-motors system into a 3-motors system to achieve such level of performance (mainly confined to increasing the gear ratio of the film transport system but fundamentally, it is the same with EOS-1/PDB-E1 combination), the Power Drive Booster is NOT just an alternate power source accessory like the Power Pack E1, but rather, it is also a high power motor drive unit with a drive shaft (you have to remove the cover of the motor drive coupling at the base of EOS-1N to mount it. (the removed camera's cover can only be store inside the GR-E1 standard hand grip slot for this purpose). In answering the latter, I should say that was one hell of a mistake Nikon made to the F5 because one of the key element of a professional class SLR camera was compromise - modular design to permit photographers to custom setup/decide from bare basic configuration.

You think that is all ? Not quite. In addition as a speed demon, the Booster Drive also provide a few nifty features not found on the Power Pack E1. There is an additional shutter release button at the end of the grip to facilitate vertical format shooting. Further, a vertical AE lock button is also being provided so, you don't have to struggle to stretch your fingers back to activate this commonly used feature in auto-exposure mode. This button functions in the same way as the AE lock button on the camera. Overall, except for the added weight (err . real heavy + bulky ..), but it was designed to improve efficiency and operational ease during shooting.

Use singularly or in combination with the companion power pack, one of the key element in the design of the camera was comfort yet secure hold, with the photographer's fingers easy accessed to two of the main control at the front and rear section. The acceptance of previous EOS-1 (see above) of this design concept was carried forward into the next generation EOS-1N.

Canon EOS-1N HS (Canon EOS-1N when equipped with the POWER DRIVE BOOSTER E1) Equal operability for both horizontal and vertical holding: Single-handed operation is possible. Note: With the Power Drive Booster E1 with modified circuit (can be identified by the AE Lock symbol * on the side of the vertical AE lock button); AA -size lithium batteries can be used on later improved version of the PDB-E1.

Canon BP-E1 Power Pack for Canon EOS-1N
EOS-1N DP (Canon EOS-1N when equipped with the AA BATTERY PACK BP-E1)

Lighter & more compact than the bulkier PDB-E1. Enables the camera to operate with convenient (4x) AA 'alkaline manganese batteries (LR6), 4 x Ni-Cd cells (via BM-E1 Battery Magazine) or lithium battery pack (2 x CR5) which has far superior characteristics in low temperature. Either of the two types of power source can be quickly selected via the base battery source switcher as desired according to the condition. Note: Although Canon officially stated it can not use AA lithium batteries, but many users ignore such recommendation but such combination exist and widely being used. Maximum auto film advance rate: Virtually no difference with basic Canon EOS-1N set up (note the lack of Drive Shaft).

What about the missing featured Canon EOS-1N RS in this section ? The camera, which realizes the world's shortest release time lag and constantly visible viewfinder image, by deploying a hard-coated pellicle mirror is/was designed as a strictly professional AF-SLR camera from ground up. (It will be featured on another section). But we will discussed it briefly on power source. Due to its specific usage, Canon has decided other than the unique feature on no-blackout real time shooting, EOS-1N RS should be made with the highest performance EOS-1N configuration, which means the power source should be an inseparable component. So, it has a fixed Power Drive Booster E-1 attached permanently. As targeted audience for this camera was entirely aiming at working professionals or scientific researchers (Errr... may be the serious amateurs as well); there is no purpose in to be so considerate to serve multi-users market segment as with Canon EOS-1N.
