Simple_Form and Simple_Fields_For and working in Form_Tag, Fields_For

I have this form and i got it working as i want:

<%= form_tag(update_individual_photos_path, :method => "put") do %>

<%= fields_for "photos", @photo do |f| %>        ................. <% end -%> <%= submit_tag("Post") %> <% end %>

But i would like to move to doing this with simple_form_for and simple_fields_for but i cant get it working. Looks like simple_fields_for cant work with "photos", @photo ?

Is it possible to call Simple_Fields_For with the same syntax as Fields_For ?
