I dunno. I'm one of those who have had multiple camera systems in the past. In the '80's and '90's...the film years....I had/have Pentax as my go to 35mm SLR system. Then I had/have as my medium format system, my Mamiya 220 Pro F 6X6 and attendant stuff...than my well used, old Leica 11f 35mm...mostly because having a Leica Rangefinder always and still does... appeal to me. The Leica is indeed a fine camera, even my ancient version...but in the end the pictures were no better than my Pentax pix.
The reason I started with Pentax as my key to the SLR world was simple. Back in '68 my publisher boss told me I had to make myself more useful and take pics, in addition to my other duties. He said get a Nikon or a Pentax SLR 35mm...as pictures needed to be 'publishable'. I checked out the cost of a Pentax SLR and a Nikon SLR...there was a $ 30 difference and back then for a young guy...$ 30 was nothing to sneeze at. So I bought the Pentax and stayed with them ever since.
Just imagine thirty bucks ...50 years ago...determined my prime camera system and I've bought plenty of Pentax stuff since then.
Thirty...lousy...bucks !
If it wasn't for the 30 dollars, I might of been a Nikonian rather than a Pentaxian...and I could of been a contender...to quote Marlon Brando form the movie, On the Waterfront.
Not so. I've been more than happy with Pentax and although like many I suspect, I did consider over a number of instances over the past half century...to change...to go from Pentax to completely go to Nikon, Leica RF (used), Canon, Nikon, Fuji then Canon and that last decision was made in 2017.
But I hemmed and hawed, thought about how good Pentax gear has been and how it still is at the top...in my mind and continued with Pentax.
As I often times say, the older and more experienced I get, I have come to the stark realization that good pictures don't (always) result from the latest 85mm F 1.4 lens...it's more dependent on how good the photographer is.
If you spend more time and effort analyzing why Brand A is going to improve your work over your current Brand B...that is not the answer to your problem of taking good pics. The thing that has worked best for me is practice, taking more and more pictures. Getting out there, Taking pics. Looking at those images and seeing where I screwed up (digital monitor is great for this) and making adjustments and trying again.
I've learned more about photography...taking pictures.... than I have reading cross analysis articles about what I need to have (equipment wise),.
I'm no Eisenstadt, no Karsh, no Adams...but my picture quality has improved over the years (I know this for sure as my wife has told me
) from just getting out to some place, some event and clicking away...but not mindless clicking...but thoughtful, self analytical about what is mediocre work or good work...on my part.
Most of us have known those photographers who have gone from Pentax...to Canon..to Nikon...to Fuji...etc.,,in quick succession and in the end...their pics still look the same.
I see these quixotic journeys in search of the ideal camera equipment as expensive and although I hate to use this word as a Pentaxian...'doomed' to failure.
