Originally posted by Kunzite But when someone says, "I wish Pentax had a 48mm f/1.03 lens, XXXXX other brand has it" he's likely trolling, and not intending to buy such a product - if it were to suddenly become available. There's no DSLR maker offering such a thing - so that other brand must be a mirrorless (was that supposed to be some Nokton 48mm f/0.95?). Another cue from your example: the D FA* 50mm f/1.4 being deemed as "not cutting it"; and the pattern is complete.
Such is the nature of your example.
OTOH, when someone says "this lens isn't cutting it", it's only natural to ask for examples. It's actually giving that man the benefit of doubt, the occasion to support his claim.
That was merely an example I designed, I wouldn't take it too literally. Yet I'm not sure we can adequately
know someone is really trolling in those matters.
And by trolling, I define that as making comments with the express desire and main purpose to get a rise or reaction out of someone.
People are fickle.. their wants, desires, and even needs are in a constant state of flux. Plus, we are prone to making mistakes or miscalculating.
So I can see the situation where someone says they really want something, then days/weeks/months/years later they decide they really want something else. Plus new items come on the market, they look more enticing.. and sometimes the want is more focused around the non-optical properties of the lens; There is also housing, weather sealing, focus motor, weight, size, feel, filter threading, etc. Photos won't provide any measurement to those, should we have some definitive way to judge a photo to prove one way or the other their need of a product (and we do not).
