So with all my used FE lens acquisitions of late, I'm wondering if I can downsize my lens collection. I'm thinking I can start with many of the APS-C lenses I still have for the A6000. SEL18200 - Pretty much have to keep this, as it's the lens my wife uses most. I might consider trying to get her to use the SEL24240 instead, but there will be times when 24mm on APS-C just isn't wide enough, so the SEL18200 seems to be a reluctant keeper. SEL24F18Z - A nice lens, although she doesn't use it all that much. I have her take it if she's meeting the girls for dinner, and might need to take some indoor low-light pictures. It's small enough that it doesn't get in the way if she has to use the pop-up flash. An alternative would be to let her use the SEL28F20. That would also be okay when using the pop-up flash. But it's not quite as wide as the 24, and if you need the UWC, then the flash is definitely blocked. SEL50F18 - Least used of all the lenses. And the SEL55F18Z should work just as well. SEL1018 - Rarely used, and with the acquisition of the SEL1224G, I wonder. Then we get to the FE lenses... SEL24240 - I pretty much am convinced that I no longer have a need for this beast. I would much rather be using the SEL24105G and SEL70200G, but sometimes switching lenses is inconvenient. Is it really worth keeping for the off chance I need an all-in-one for some occasion? SEL28F20 + SEL075UWC - A nice compact lens if I want to carry something small, and know I will be needing wide angle. Shot most of the day at a state park with just the 28 (No converter) for a surprise birthday party. Painful to add/remove the converter though... Well, a pain if you want to put the rear cap back on, or need to put the lens hood back on the 28. SEL55F18Z - Great little lens. But do I need it since I acquired the SEL2470GM? SEL90F28M - Chose it over the SEL85F18 to have to chance to do macro, or product photography. SEL24105G - Great walkaround lens. Obvious keeper. SEL70200G - Much sharper than the SEL24240. Obvious keeper. SEL2470GM - Got it only a week before the SEL24105G. Debating on keeping it, but really like it for indoor portraits. Perhaps even better than the SEL55F18Z, mostly because the zoom makes it a much more flexible option. I keep flipping between it being a must keep, to thinking it might be a maybe. SEL1224G - Just got it, and haven't really had the chance to use it, but I know there are times when I would like something wider than 24. Seems like an obvious keeper. So if I'm just going for a walk, the A7RM3 with the SEL24105G is great. For a bigger hike, the sling/backpack with the SEL1224G, SEL24105G, and SEL70200G should work, although there is no room in the sling for the filters to be used with the SEL1224G. I could go full backpack and do it, though. And of course, the lenses I'm fairly sure I could part with (SEL50F18, SEL1018, SEL24240), are not going to get much money back. But I gotta start saving somewhere for the SEL100400GM, right?
