agree with where you are headedLots of good advice to ponder. As for grandchildren, our son likes to move around a lot. Since college (Syracuse), he's lived for about two years each in Istanbul, Brooklyn, Malmo, Taiwan, Colorado (Boulder and Denver), Bethesda, and now he's in London. We suspect that, if he does settle somewhere, it will be far enough away from Boulder that we will be traveling to see any grandchildren. That 50 F1.2 is definitely not a lens to take on long plane journeys. I've pretty much decided to sell my 85 F2. The two advantages over my 85 F1.4 are IS and close focusing (the size and weight are close enough). The IS doesn't affect me, because I have IBIS in all my bodies, and I'm shooting the 85 at fairly fast shutter speeds anyway. The close focusing is nice, but if I really need to get close with an 85, I can use my 100 macro instead. The close focusing on my 35 F1.8 is more relevant to me, so I probably won't sell that. While I'm getting a quote from MPB for my 85 F2, I might see what they would give me for my 50 F1.2.Great points!I agree. If the 1.4 is working to the point where 1.2 stops getting any usage, I would say the difference will likely not be enough to unmoth it for that once in a blue moontoo many ifs to bring the heavier f1.2 out of mothballs imoIf you would ever do a posed portrait you also have that great RF 135mm f/1.8.According to Toothwalker further down this thread, the patent shows it to be F1.24, which agrees with most reviewers who describe the difference between the two lenses as 1/3 stop (though, to be even more pedantic than most of us are already being, that would put it in between 1/3 and 1/2 stop). In any case, the difference between 1/3 and 1/2 stop is imperceptible. The difference between F1.2 and F1.4 on my 50 F1.2 is just about imperceptible as it is. I would never pay twice the price and accept twice the weight and size just for that difference. There would have to be other differences too. Which there are, but some of them work in favor of the cheaper lens (like lightning fast AF). I bought my RF 50 F1.2 before the F1.4 VCM version was available. I still have the F1.2, but I have barely used it since getting the F1.4. thunder storm predicted I would sell it, and I said I'd still keep it for dedicated portrait sessions. The thing is that I don't do many of those. Most of my portrait style shooting is event shooting, where the weight of the kit is pretty important to me. So, I'm still pondering whether to sell my 50 F1.2.f1.4 is 1.414 to be precise, down 1/3 stop is 1.26 or f1.3 cannot be qualify as true f1.2. Judging f1.2's size, weight and price, I tend to believe it is true f1.2I used to think that, but learned recently that F1.2 is actually only 1/3 stop faster than F1.4. The actual number is probably a little over 1.2.
However,
If there's any chance you will get grandchildren you could just mothball it. Before kids start walking (fast) the 50mm f/1.2 would be my ideal RF lens. The focal length is flexible enough for indoor shots, the light gathering is as good as it gets and colors and rendering are beautiful.
Just my 2 cents.
eg, removal of backdrop clutter is just a tad better with the f1.2 but depends on separation and character of backdrop to begin with
enjoy the lighter vcm instead
use the sale of the f1.2 to buy something that will get use!
Besides, it keeps losing resale value while it is sitting unused. Better to cash out now and use the money for something that excites you today
do you think you'd ever go for the great 10-20?
