While I have been a "budget" buyer for some time, steadfastly claiming that the esteemed Sony/Zeiss 24mm f/1.8 APS-C E-mount lens was way too rich for my blood, I've come to like the focal length, often gravitating to it on my SEL1855. And while I like my Sigma 30/2.8 Art well enough, at f/2.8 there are times (like in dimly lit rooms at Christmastime with family) where I long for the faster speed of an f/2 or f/1.8 lens. That being said, I've been actually thinking about splurging on an SEL24F18Z, which is currently US$200 off at Amazon and B&H, etc. However, the still hefty $900 price tag is... scary. And then I look over and see the Sony FE 28mm f/2 sitting there for $450. I know that at 28mm it is the equivalent of 42mm on APS-C, a bit narrower than the 36mm equivalent SEL24F18Z, but it is half the price AND is an FE lens that would carry value over for the time when I (inevitably?) move up to an FE body. So, my question to the forum, particularly those who have or have used both lenses on APS-C, is whether you feel that the 28/2 might be a suitable replacement for the more expensive APS-C-only Sony/Zeiss 24/1.8? Thoughts everyone?
