The 'hard truth' of photography is that the exposure triangle MUST be 'satisfied' to get the shots one wants to get. In some shots, 'satisfying' the exposure triangle can only be accomplished with higher-end gear. However, getting a satisfactory exposure is more about ones knowledge of the exposure triangle, DOF, shutter speed limitations, lighting, etc, and having the
skill to make the appropriate choices in the time available.
I've always been fascinated by no-flash, nighttime photography. I quickly learned that the 'fast film' of the day...Kodachrome 64 and later Ektachrome 100 and later still, 200, was the limiting factor to my nighttime photography. Knowing the limitations (and having a light meter in my pocket), I managed to work within those constraints and restricted my night work to non-moving subjects where I could use shutter speeds measured in seconds, or even minutes, with the camera fully stabilized.
Fortunately, in the intervening 40 years or so, the ISO speeds achievable by todays cameras allows far more flexibility in low light work. I recently pushed my gear to its very limits shooting handheld at ISO 25600, 1/160th to stop subject motion blur, and at f4, because that was wide open with the lens I had mounted. Would those shots have been possible with entry level gear? No. So, score one for "it's the gear". But for those not trying to get a near impossible photograph in a dark room, my level of gear is not necessary. Similarly, I don't have a fast 400mm prime lens as I don't do bird photography. Nor does 'frames per second' matter to me as I don't shoot sports.
So, in the end, I have to agree with fjrabon about what's needed to consistently take great photographs:
"1) Ability. I'll stop short of saying natural talent, because I'm not convinced that it can't be completely learned, it may just take some people more lessons to get it.
2) the appropriate gear for the task at hand.
3) the right opportunity."
Although I would rather use the term: "knowledge and skill to use it" than "ability" in #1 above. Regardless of the word(s) chosen, it's a combination of experience and learning.
