In these Canon F-1 vs Nikon F2 discussions, the importance of the well-heeled amateur market to sales and popular awareness of nominally "pro" cameras in the '70s always seems to get overlooked. The simple fact is, the (original) Canon F-1 had absolutely zero sex appeal to the amateur with enough money to afford it. Prior to its AE-1 swinging a wrecking ball that destabilized the entire camera market, Canon was spinning its wheels with well-built but basically ho-hum (to amateurs) SLRs like the FTb, TX, and EF. These were competitive with Minolta SRTs, Pentax Spotmatics and Nikon's Nikkormat line, but didn't particularly stand out on the camera shop shelf and scream "kewl kid". This is the crux of why the original F-1 sometimes seems to be forgotten, while there's a rabid cult-like following for the Nikon F2. Sales numbers = awareness, awareness + larger number of available surviving examples boosts cult status decades later.
Photographers who weren't around in that era and old enough to be interested in cameras really have no conception of the emotional headlock Nikon's F and esp F2 had on the imaginations of 35mm SLR buyers: they were THE aspirational SLR cameras of the early to mid 1970s, period, no credible competitors whatsoever. Amateurs were so desperate to be associated with Nikon, even their idiotic strategy of naming their non-pro cameras "Nikkormat" (WTH?) saddled with severely cropped off-center viewfinders succeeded wildly. The only thing more common than protests on college campuses in the '70s were the student-wielded Nikkormats documenting them.
That is not to say the original mechanical Canon F-1 (and F-1n revision) wasn't a worthy option for professionals vs the Nikon F2: it most definitely was. To a certain degree, Nikon was trapped by its runaway success with original F, which constrained how imaginative they could get with a followup F2. I love the F2, its my favorite camera of all time, but it was forced to carry on some quirks from the original F instead of being entirely clean-sheet. Canon cleverly seized on this, "correcting" several of the glaring deficiencies inherent in the F/F2 design, and boy did they promote these improvements. Unfortunately, it wasn't enough to sell the F-1 in quantities that would enable cult status on par with the Nikon F2 decades later. The Canon F-1 sold successfully into the pro market to photographers who recognized and exploited its advantages over the Nikon, but stalled there. Nikon, OTOH, easily sold a few hundred thousand F2s to amateurs, while virtually owning the pro market.
Part of the problem was amateurs didn't care about features so much as they cared about status, so the excellent solutions and updates embodied in the F-1 didn't grab their attention. For example, most would never interchange their prism for another viewfinder, so Canon's beautifully-engineered slide-off finder system and in-body meter that retained metering with all possible finders was met with crickets. Ditto the advanced F-1 motor drive with more versatile power and grip options, and integral sync with the camera shutter cycle: most amateurs were never gonna buy a motor that cost more than their camera did, so this too sailed right over their heads. Canon also bet the farm on a semi-spot selective area metering pattern in the F-1, a boon for pros but fatal for amateur usability in those days
Canon launched some nifty F-1 ad campaigns in Popular Photography etc, featuring younger hipper pros doing super-cool work like shooting album covers for The Who, but it didn't increase sales to non-pros by much. And Nikon somehow kept making lemonade out of lemons with the F2, keeping it evergreen and ever popular. You say the F2 sucks because it can't meter with all its viewfinders? True, buuuttt... have you seen our snazzy new meter prism with two big red LED meter lights that reads down to available darkness without a huge clumsy booster? Bang... zoom... F2S sales soared. A couple years later: have you seen our newer smaller LED meter prism with 3 count 'em 3 LEDs and (wait for it) memory-free silicon cells? Usher in the legend of the Nikon F2SB and F2AS.
Canon couldn't even get status traction from its F-1 FD lenses being engineered from scratch for shutter priority automation when used on the F-1 with its AE finder, because Nikon offered the most PT Barnum sideshow attraction ever seen before or since: the DS EE accessory, a little motor that attached to the F2 lens mount and physically turned the aperture ring of all Nikon lenses according to the meter reading. Slow as hell AE, burned thru its battery within 40 mins, but golly gee was it trippy and fun to play with (and looked hella better than the gigantic Frankenstein-esque AE finder attached to the Canon F-1).
History repeated itself somewhat when Canon replaced the all-mechanical F-1 with the more advanced electromechanical F-1 New. Compared to the Nikon F3, the Canon F-1 New was so much more advanced and versatile it wasn't even funny. But Nikon managed to get their F3 to market a few months earlier, soaking up all the attention for "first professional electronic AE SLR". The F3 was as much a sensation with amateurs as the F2 was, if not more so: it sold faster than Nikon could make it. Personally, I can't stand the F3: the dismal meter display alone is enough to make me want to take up another hobby, but everybody who could afford one wanted it in 1980 (and its still one of the hottest second hand film cameras). Poor Canon was once again shunted aside into also-ran lane: existing Canon pros loved the F-1 New, some pros on the fence about the F3 jumped ship to it, and it picked up much greater amateur appeal from association with the AE-1.
But it didn't sell in crazy numbers like the F3. Maybe because once again Canon made a camera pitched fully at pros with no glamorous compromises to entice amateurs. It had multiple AE modes, but some required an optional prism or buying a motor drive. You could choose among three meter patterns, but doing so required changing the focus screen. Meter display in all modes was far more informative and readable than the F3, but the F3 could be used by a clueless dentist to make passable exposures every time without pre-configuring a particular F-1 kit. More crucially, the clueless dentist could swing the F3 boastfully off his shoulder on his friend's yacht and get an awed reaction, while few of his cronies would have recognized an F-1 New (they might have mistaken it for an A-1 tho, and applauded that).
It took the rise of autofocus for Canon to finally free itself from Nikon's shadow in the pro as well as amateur markets with its entire camera lineup. It also took a lot of guts, and a lot of luck with their bet that the future lay in fully electronic lens couplings, but they ended up dominating the camera field and reducing proud Nikon to seemingly permanent catch up mode (Nikon sometimes has the edge in technology and a few lenses, but it never shifts their market position anywhere close to Canon's). So Canon got its revenge after all, eh?
