Whilst Looking Though,

a Russian based web site,

 called LiveJournal, I came across the site of Andrew Qzmn, who has taken some wonderful photographs of abandoned Russian farms,

 he uses a variety of cameras, 

including a mirrorless full frame camera Sony A7r, lenses, zeiss 35mm f2. 8, zeiss 24-70 f4, you can read about it here, he also uses a Canon 7d mark2 which is old but works fine, a Canon 5d with a set of lenses: 16-35 2,8L; 24-70 2,8L; 70-200IS 2,8L;100-400IS L; 100 Macro 2.8. sometimes also using a Linhof MT 4x5, in the pre-digital era of film, he used amongst others a Canon EOS 50, Horizon 202, Kiev 60, for more of his pictures have a look here, 

 keeping to abandoned building this one caught my eye, 

a floating house/farm building, it is located 1 km from Krasnosilka, Odes'ka Oblast (Ukraine), but it is not a house, it is a building that is a part of a potato sorting station, the metal bottom cones used for loading potatoes into trucks, usually they look like this, it appears that it is a common construction in agricultural regions of Ukraine, I wonder how many more unusual abandoned buildings there are out there?
