Hi guys, Im looking for some help from MF experts such as yourselves. Im looking at a Bronica SQ-A or EC-TL on eBay. One question I have - that I cannot find anywhere is in regards to the Depth of Field. When focussing using the WLF, does either the SQ-A or EC-TL viewfinder show depth of field? As in, does the view finder show the background blurry, when focussed on something close? example: I read that there is a depth of field preview button on the lens of the SQ-A? Does ths mean by default you cannot see depth of field through the view finder, with these two models? Apologies if this is a basic / nub question. Im new to MF equipment!
