The 1.1 DOF is just too narrow. I stick with 1.5 or 1.4 at the most, and use sparingly.

Is that a 35mm f/1.4 or a 50mm f/1.4? That makes a lot of difference. Fast 50mm lenses are (much) more difficult to focus. An 50mm f/1.1 is really demanding. It would be wise to try a 50mm f/1.1 on your R2 before you buy it.

I never sold my 1.1, btw 😎

This is where the 1.1 shines: fast speeds. Stopping down (these are not the best shots overall, but should give a good idea of performance)

In short, the 1.1 is adequate stopped down, I suspect the 1.5 may be sharper on the edges at F/8, because the 1.1 def looses it a bit.
Both the 50 cron v4+ and ZM50/2, and of course the lux asph, are much better on the edges than either of these very nice lenses.
Much worse on the edges at all apertures is the Sonnetar, but it goes with me evenings more often than my 1.1. Why? Tiny and delightful 🙂 My main daylight 50 is the cron v4.
Between these two as my only 50 I would take the 1.5, with biggest issue being size and weight.
I was very surprised at the size, but moreso at the weight. You can't really compare it with a modern SLR lens--at least I can't, since any Nikon lens I have of similar size has a large percentage of plastic, and MUCH less weight. Ultimately, size just takes up more air; weight is what you feel.
By the way, that's a picture of my wife, who's an artist but not a photographer, so she has no particular bokeh opinions or even recognition that it's something people think about. When she saw that shot, the first thing she commented on was how much she liked the way the background looked. Some people have commented on other threads about how the lens seems to have more depth of field than it should, and I think that's due to aberrations similar to what many old lenses have that tend to spread the focus out in front and especially back, giving a bit of 'glow' in the process. But this lens is needle sharp stopped down, not a disappointment at all in that respect.
I have never used a CV 50/1.1, but from what I have seen posted online, I am staying with my CV 50/1.5 ltm and I do not think about buying a CV 50/1.1. Instead, I bought a Zeiss Biogon 35/2 to complement my CV 50/1.5. Having a larger max aperture is not always the decisive factor.
Food for thought.
I see, I find it so hard to gauge the size of lenses without ever having seen them, I think I've been underestimating the 1.1!\
This is why you need to complete your personal profile info: for all we know, you live right next to me, and in five minutes you could be trying mine on your camera. Or maybe you live next to someone else with one, but you'll never know! 🙂
Yes I agree, it's not the larger aperture I'm really bothered about, it's the lens's characteristics and performance. I've got the 1.5 and the 1.1 available to me at the moment at about the same price, but I cannot decide :bang:
If the market values for both lenses are roughly equal, go with what your instinct tells you to do. If the 50/1.1 sells for more money, buy it. Use it. If you like it, keep it. If you do not like it, sell it and get the 50/1.5.
B&H new price for the 50/1.1 black: $899 ......................................... CV 50/1.5 black : $799
It is a $100 difference only.
Yes there is only £50 between the 1.5 and the 1.1. I think I'm headed towards the 1.5 now, just because I know the lens and I don't think I want the size of the 1.1. Thanks for your input! 🙂
What are your other 50's ?
That could swing the decision one way or the other 🙂
From cameraquest.com:
"Rangefinder Base length of 37mm: This translates to an effective rangefinder base length of 37mm for the 1.0x magnification R3A, and 25.6 mm(37mm x .68 magnification) for the R2A. In other words, the R3A's rangefinder is 74% as long as the standard .72 Leica M finder, while the R2A's rangefinder is 51% as long as the standard .72 Leica M finder with EBL of 49.32."
it would be really difficult to hit focus at 1.1 with an R2a. As the specs above show, the R3a would be the Bessa to use for this. There is a big difference with dof between 40mm lens at 1.4, and a 50mm at 1.1.
Also, the 1.1 will block an awful lot of your VF.
