developing medium format wont cost u any of ya limbs btw... In Seri Kembangan, there is a shop dat charge u RM 5 for processing it, n RM 1 for each exposure (pictures) dat u haf on the film... d real problem is to find which shop that has the capability to develop the medium format... a real challenge for me n my sis earlier on...

suprise that people over here ask about medium format.

it's a nice camera that i have been using for quite sometime before i upgraded to largeformat.
i used to have a seagull, then a hasselblad 503cw, then a mamiya 7II.

i doubt that you can find a hasselblad for rm 1k... well, i might be wrong though... for mamiya, yes... you can find a used RB67, plus one lens plus one film magazine for rm 1k plus.

film wise, slides film is more or less rm 12-15 per roll... i use provia 100F and it cost me rm 12 per roll... colour negatives i get the normal kodak for rm 8.50

depending on format the film will give u different number of shots per roll...

6x4.5 = 16 shots (mamiya 645, pentax AF, contax AF)
6x6 = 12 shots (all hasselblad, all rollei)
6x7 = 10 shots (mamiya RB67, RZ67, pentax67)
6x8, 6x9, 6x12, 6x17 all these format are not really popular and the cameras are really expensive... so no point in telling u.

medium format cameras system can be constructed parts by parts... and therefore, if you want a light meter in there, you can get it and attach it to the camera... if not, the camera is basically without a light meter... and you wont know what exposure to set unless you have a hand light meter with u.

and yes, most of the medium format cameras are mechanical and therefore, no electronic component in it and therefore, no 10FPS, no auto film advance, no auto film rewind... you have to do everything yourself... oppsss... no autofocus as well.

some of the medium format cameras come with the auto features like autofocus and stuffs but i dont think you would like to venture into that category first.

itz my sis's btw.. aint mine, but we share the same interest in lomography cameras.. but i decided to go digital then.. It is Holga 120CFN...

owh, my bad.. it wasnt 4x4.. but 6x6 eh... 
cross processed is wat usually make those lomo pics to come alive, i suppose... pity, the shop dat we went in Seri Kembangan can't do cross processing... finding the shop dat sells d film is a challenge by itself, n finding a shop dat can do cross process nowadays, is even more challenging.. i havent found any shops around here dat carry out such process... i wonder is YS Photo in Seri Serdang is able to do dat... hrmmmm
