Hi everyone,

Need some opinions on what lens to buy next.
Currently have:
Body: Canon R6
EF-S 10-18 mm f/4.5-5.6
EF 70-200 mm f/2.8L
RF 50 mm f/1.8

Considering:
EF 24-70 f/4L IS USM
EF 24-105 f/4L IS II USM
RF 24-105 f/4L IS USM

Which one would you buy? Looking for an all-around zoom lens that fits my budget (<$1000).

Unless you have a special use-case that needs EF, go for the RF24-105L, it's a great lens. The copies I rented all performed well. I didn't buy it because in that range I'd most likely be traveling and then I'd rather use my EOS M :)

FWIW, my thinking is:

Get RF 24-105 f/4L IS unless you would really value the (semi) macro mode of the EF 24-70 f/4L IS, in which case get the EF 24-70 f/4L IS. (Once you add the EF/RF adapter, the EF 24-70 f/4L IS wouldn't really save you much, if any, size or weight, so I have ignored size and weight differences.) Since you own an R camera, I wouldn't even think about the EF 24-105 f/4L IS II.

To try to explain my thinking ... I have the EF 24-70 f/4L IS and I have used the EF 24-105 f/4L (original version). I prefer the IQ of the EF 24-70 f/4L IS, and the macro mode and slgihtly smaller size and lighter weight are nice bonuses. Everything I have read is that the EF 24-105 f/4L IS II is very similar optically to the original version. The mark II is notably bigger and heavier too. I haven't personally used the RF 24-105 f/4L IS, but from what I've read and seen it is at least a bit better than both versions of the EF 24-105L, it's about the same weight as the EF 24-70 f/4L IS, and it gives you the extra zoom range. I really do like my EF 24-70 f/4L IS and it has served me well, but if I was starting now in the R system, and I was happy with an f/4 lens (you could always think about a f/2.8 :)) , I think personally I would go for the RF 24-105 f/4L IS so I didn't need to use an adaper and becasue I would find the extra zoom range over EF 24-70 f/4L IS useful. Anyway, as I've said, I haven't actually used the EF 24-105 f/4L IS II or the RF 24-105 f/4L IS, so probably best to take my views on this with a grain of salt :)

Based on my own experiences with both (EF 24-70 & RF 24-105 f4), the EF 24-70 is visibly sharper, and I often use the macro option.
the RF is a good lens, mechanically certainly better than the EF, so it's basically 105 mm vs. macro+sharpness...
But: if you do not own a DSLR, go for the RF 24-105 plus an RF 35mm macro.
