Hi Ken
The 18mm and the 24mm benefit from stopping down, the 50mm and 70mm are a different thing altogether and are fine wide open at f2.8, as is the 20 - 40mm zoom, if you can find one, but they all benefit from f4 or smaller of course. I have seen no trace of CA in any of my 110 lenses, but they all need a lens hood, they all flare easily.
Looking forward to your pics, might do some myself as we have Sun!! For the first time in a few weeks.

You can't stop down a 110 lens as they have no diaphragm mechanism. The aperture is defined by the degree of opening of the Auto 110 shutter.
Best regards, John

Sceptical as I am of home testing lenses, here goes.
As John says the 110 lenses have no diaphragm since this was controlled within the camera mechanism so all shots are fully open at f2.8; as screwdriver notes the 50mm is noticeably better. All shots on a very heavy tripod and the sharpest focus-wise from several. All straight from the camera.
I have included the 01 prime as a reference.

18mm 110

In these the focus is on the nearest tap

Well that was the most boring thing I've done in a while!

Just bought a set on Amazon for £10, worth a try at the price I think

I haven't had a chance to try them yet but a 70mm has arrived to complicate life farther!

The thing that is such a coincidence is that the Lensbaby aperture discs are a perfect fit into the Roxsen adapter. I do mean perfect.
The combination of the Q with adapter, 70mm f2.8 110 lens and even a SMC Takumar 200mm lens hood is beautifully balanced and SR really did a fine job on the few pictures I took.
Why bother with a Q10 when SRS are selling Q's at such low price

I love the look and the colour options! The Q never caught my imagination, however, the Q10 holds my attention like my little 110 does.

You can have any colour options you want on most any camera, the 'leatherette' covering on the front of most cameras can be changed for anything you want, it's only held on with double sided tape apparently, a die cut for the Q snakeskin is what I'm waiting for as I had on my old ME Super.gartmore wrote:

Chromatic aberration, lacking in contrast, soft and diffused highlights. Might be good for portraits though.
I'll take some pictures in controlled condtions tomorrow and post them.
