Thank you all for the answers.
I think Rollei / Agfa Film is for good weathers , nobody does remote sensing-even large percentage of satellites - at bad weather , isnt it ? I visited flickr and low contrast images are bad. But this films color rendition reminds me old kodak films. If I go to Mediterrenean Coast this summer , I will try to buy it.
I dont need to buy Ektar also , its hot and can be made at any internet photo retouching software with cheaper films.
