Today I used a lens I also bought in Holland at he store I talked about before. I was really exited by this lens because it feels really good in the hand. It is nice and heavy and it zooms from 35 to a 105mm which I like for walking around in a city for instance. It also has a dedicated zoom setting that lets you get close with a 1:3 magnification, also nice for a city walk because now you can take some nice closeups of random details. I tried to find out some more details about this lens and Revuenon but besides some reviews of other lenses from the same manufacturer I found little about the brand itself. I wanted to know more about Revuenon because the lens feels good and seems to be of some good quality mechanically but optically it is terrible, at least my lens is. There is a small crack in the front lens, something you can see on some of the photos. Maybe this lens fell down once and shifted some lens elements internally. The problem is that you can not get a sharp focus on 35mm, you have to go to 40-45mm to get something in focus. If you are at 35mm you can “turn on” the macro setting and get focus that way but it is strange. This might be caused by a lens that is shifted internally but there are other problems, the amounts of chromatic aberration, specially at 3.8 is something you don’t see anymore at even the cheapest lenses made today. The glare is also noticeable and the lens is soft overall but specially in the corners and it has low contrast. There is also a lot of barrel distortion even at a 105 mm.
I bought a cheap reflector for my large flash on 
the best I ever felt. Today I used it meanly at an aperture of 1.4 to see the results. You cannot focus really close, around 45 cm from the sensor but at that distance there is not much depth of field. Tomorrow I will try it at other f-stops and from longer distances from the subject.
Today I used my 300mm Nikon lens on my X-t1 to try out manual focus with this kind of lens. The X-t1 has this focus aid that shows you a small zoomed in part of the screen besides the main screen and this works great. All the pictures are taken hand held with a shutter time of 500. The pictures of the flower give a nice mood and because of the aperture of f4 only a small sliver is sharp. The picture of Darth, our cat, shows a good sharpness in the eyes and the bridge is sharp to, at least part of it because the aperture was also f4. The butterfly was more difficult to get sharp but that was because of the wind, I shot a burst of pictures and prayed for the best, something a normally never do. Overall manual focusing works fine with this kind of lens.When I use this lens, made between 1987 and 2000, on my Nikon D7100 you can use the autofocus but it is slow, there is no motor in the lens like you have with modern lenses, it’s all mechanical and you notice, and hear it. As long as the subject is not moving to mush and you are not in a hurry it works great. .
