Thanks Ray. I shoot due north, but I am hemmed in by the die cast table, masonry chimney, & 1-3 cats. In the summer a huge 10 x 14 foot red umbrella, and a large tulip tree on the left further constrict shooting. Direct lighting in that area is a short lived affair. The cats always like helping by rubbing the 600mm lens shade, and eeeeeekking at the birds. Two or more cats and I put the neck strap on as they jockey for position.

James, after seeing your BTS post a couple of pages back, I can now also appreciate the lighting that you get there.

After the 28mm 3.5 PC was questioned I looked at some of my old photos and they did not look critically sharp, now that the doubt is cast I will have to do a quick backyard compare - present will be the rangefinder 2.8cm 3.5, F mount 28mm 3.5 NKJ, 28mm 2.0 N.C, 28mm 2.0 ais, 28mm 2.8 ais, and the 28mm 3.5 PC - centered - off center it is what it is, not the best but gets the perspective work done, and others can't do it.
This one here is shifted, probably 1:8 or 11. seems sharp enough to me, except for the very top of a very high tower. focusing was for the bottom corners. 100% on Flickr.
Rafael, I learned the hard way a while ago that the near the top of the frame the sharpness and distortion are impossible to deal with after a significant shift. I had someone's face in that part of the frame. Needless to say that photo got summarily deleted.
Wide open, I think the OOF highlights have more defined outlining with the f1.8H. I think I also see a little more swirly to the bokeh with the 1.8H. I agree, stopped down to f4 they seem really similar.
This next comparison is with the 105 f2.5 AIS vs 105 f2.8 AIS Micro.
Once again both are excellent, and through my glasses I honestly can't tell the difference. IMO the 105 2.5 and 2.8 micro were among the finest lenses of their generation. I use the successor 105 2.8 VR on the Z5 for focus stacking of flower close ups and have had superb results.
Saph - That tree at f/2.8 is wonderful! The H in HC must stand for hex.
I hope this isn't too repetitious.
Although the lighthouse is small, approaching it pre-dawn involves a 1/2 mile walk down a dark path periodically lit by blinding beams, and it's like nearing a fantastic huge silent helicopter!

I need to explain these tree ornaments. My son got a 3D printer, and for his first print - he printed a bust of president Obama. The printer got stuck and didn't finish. He says "dad, I got something for ya", and I said, "where is the top of his head?". He promised to make me a complete bust, but on the day of gifts he gave me these. We laughed, and then he did give me a complete one.
