There’s a lot of “grass is always greener on the other side of the fence” going on in people’s minds these days. It seems that every other email I get has some variation of the theme in it.
We used to play this grass is greener game between Nikon and Canon brands, first with film SLRs then later with DSLRs. Now many are playing it between DSLRs and mirrorless. In some cases, I’m seeing it between two companies because of customer support appearances (e.g. “Fujifilm came clean on the X-T1 light leak and is going to fix everything, but it took Nikon forever to acknowledge D600 issues, thus Fujifilm is the better company.”)
The reality is that if any camera company had paid more attention to the customer and their needs/wants, and then seriously tuned their camera and lens offerings to accomplish those things, one side of the fence would have really green grass, the other side of the fence would house a parking lot.
Meanwhile, we also have a lot of folk who are more excited about the birds in the bush than the bird in the hand. An example of this came up today when someone asked me about whether they should wait to see what the rumored 120-400mm Fujifilm lens was like before choosing between an X-T1 and an E-M1. Hmm. 600mm effective. Let’s see, a D7100 with the excellent and fast focusing 80-400mm does that just fine. Even the E-M1 with the Panasonic 100-300mm gets you there, though I’d rate that option lower than the Nikon DSLR/lens. But a rumored lens gets you nowhere.
Short answer to both syndromes: shoot what you’ve got until it’s exceedingly clear there is something better and your provider isn’t going to give you something similar soon.
