Your thoughts on the EF 28-300mm f/3.5-5.6 L IS USM lens

Does anyone have experience with this lens, owned or used one. I want a full frame in this zoom range and love the of versatility of the lens. I own one in this range but it is APS-C so I'm unable to use it on my 5d M4 and when I go MILC I would like it to crossover if possible. Anyone's experience with this on a MILC would be great.

If the weight and the price are not too much for you, its a decent lens not a great lens. I had the opportunity to get one  about 10 years ago and passed on it. So personally I would not buy one. Today you have better choices.

The lens has a push-pull type zoom mechanism which some feel is not good.

Trevor, thanks for the recommendation on the RF 24-240mm. I went out today and put my hands on both the R6 MII and the R5 with a host of my lenses and a couple of their rentals. I love my Sigma 18-300mm for my APS-C bodies but the 24-240mm was pretty impressive at $900. And it weighs almost nothing compared to some of the lenses I own in the same range.

Most appreciated sir.

And today's road trip pushed me closer to the R6 MII, the AF tracking was incredible compared to my 90D and 5D Mark IV.

Glad you are getting the results that you are aiming for.  The tracking and IBIS were both big reasons for me to move to the R-series platform.

I am a fan of both versions of the R6, I must admit, which is why I kept my first two, even when I got the MkII.  Of course, much depends on what one shoots and produces, but for my own purposes this is absolutely adequate.

I was absolutely taken with the RF 24-240USM, I really only keep the RF 24-105 f/4 for the rare occasions when I need to shoot indoors or in otherwise dim conditions, but I really don't see much difference in the optical quality when both lenses get enough light, and the reach is fantastic.  If I put it on my R5 in 1.6 crop mode I get an equivalent focal range of 38-384 and the images still look OK at just over 17MP.  For me, it's a keeper and I don't regret giving up my legacy 28-300L.
