I am tempted to sell my a7r3 and buy the a6600 and 10-18 lens. I would also add the 16-55 2.8 Sony. I like the idea of a smaller kit that will include the a7r4 and 24-105 Sony. I do not like to change lenses and have always liked using one camera with a mid range walk around zoom and another with an ultra wide zoom. Replacing the a7r3 and 16-35 4.0 Sony with the a6600 and 10-18 allows me to use a smaller bag I like to use when traveling.

Most of my photos will be used to post on the web. I am planning two trips to Europe next year. My goal is to come up with at least one large 6'x4' canvas print and several 36"x24" canvas prints for my home. I want to do a lot more video for this trip. I will be bring a monopod that is easy to travel with along with a small mini tripod I attach at the bottom. It is fairly sturdy if I do not extend monopod all the way. I use this set up for panos or for shots I know I will make a large print of.

My guess is for video the a6600 and 10-18 could be a good combo and in general good for most ultra wide shots. My hope is would also be good for fairly large canvas prints (up to 40"). I would most likely be shooting stopped down a bit with the 10-18, the more depth of field the better for filming and shooting in those narrow European streets.

I am curious if 10-18 owners are very satisfied with this lens? I love the size of this lens. From what I read corners are not good shooting wide open. I think for the vast majority of what I would shoot, including video, this will not be a problem. My guess is if stopped down to 5.6 or 8.0 even corners would be good enough for larger canvas prints. Correct me if I am wrong.

I have the 10-18 lens. I am noticing that its not so sharp at the edges. In fact if you look at the far right hand edge, I actually see some smearing.

This 11mm shot was taken with an A6300 which has been converted into a mono sensor by scraping off the CFA and this was taken through a red filter. The lens was set to f4.

The center is sharp, but I am not happy with the edges, especially the right. There is also some vignetting visible. This didn't come from the lens. It came from me not rolling back far enough a rubber lens hood I was using.

For comparison, here is the Sony 18-200 taken at 18mm and f8. I wasn't expecting to see this broad zoom do as good at the edges as it actually did. But then again, I was stopped down to f8. A green filter was used.

Adding another taken with the Sigma 10-20mm f3.5-5.6.  This shot was taken as a test shot.  And I am just beginning to see how I like wide angle images from this lens.  It is shot at 20mm and f5.6, so it is not being taken at it's widest angle.  But the edges are better than the 10-18 so far.

FYI: A mono sensor is able to show more detail than an equivalent sensor with the CFA since there is no need to demosaic the B&W image. I use SW to read the RAW file and convert it into a mono DNG file which can then be loaded into other applications without demosaicing.
