RB67 was a studio camera until recently some young photogs like to use it for outdoor shoot really a heavy metal camera.( can use for enlarging your biceps ) Would recommend the Mamiya 7ii , a 6x7 rangefinder camera, very light weight and produces sharp and brilliant images.

The 645 is just slightly bigger than the 135 format( 35mm film ), imo , you don't really get the full impact of a medium format. You can start with 6x6 and go upwards.

The weight of the RB67 and additional lenses is really no joke. You really have to be very determined to use it outdoors. Trust me, I've tried..

Yup...An average weight to carry this monster with 2 lenses is about 5 kg or more. Of course, that include 2/3 (6x7 or 6x4.5 format) film holders too. Have fun....

the Gitzo tripod in this photo here is for mounting the RB when go for location shoot.

the standard outfit for location shoot is three lenses, two bodies, one polaroid back, three 67 roll film holders, two 645 roll film holders, 5 or 6 pieces of filters, bellow lenshood, rubble lenshood for 50mm, at least 20 rolls of film.

in studio, I mount it on a Foba studio stand.

shooting with RB is not for fun.

Item #3 weigh at least 4 to 5 kg w/o the pan & tilt head attach to it (i think). Solid metal construction.

well, need a tripod able to take the RB mounted with 250mm lens.

So, do you need to mount a support holder underneath the 250mm lens that attach to the camera body? Or that only applies to 350mm & above?

[catchlights]

250mm lens don't have to, never try the 350mm lens before, 250mm lens is mainly use for shooting portraits.

Okie dokie...thks.

[flipfreak]

ok. so it seems bringing a rb67 and shooting handheld seems out of the qns then. hw abt the 645 mamiyas? possible to shoot handheld right?

[nmk]

The Mamiya 645 can be shot hand held (though A tripod would really help if you plan to do any outdoor shooting in the evening or twilight).

If you are planning to use th 645 hand held, try and use a waist level finder and a small hand held meter (using a prism finder adds 50% or so to the weight of the body and the 80mm lens).

The Mamiya RB67 is not portable, but if you are willing to lug it around, it is a lot of fun to work with.

Just to share the handling and feel of a 645 camera.
I'm using a Pentax 645N, size is about a pro-slr or slightly bigger, there's also a power-winder grip.
Overall I think weights around 1kg+ the most with 6xAA batteries.
Definitely able to handheld, and Pentax medium format cameras are pretty good for value.
Cons is, you can't interchange backs, if you need this function guess you have to look at Mamiya, not sure Bronica ones are able or not.
But some of their AF lens are rare to come by, in ebay that is.
Still hunting for the AF 150mm f/2.8 for few months already.

Not out of the question, just very tedious and bulky. I've brought it overseas to shoot street photography before. No joke.

1) AF lenses for Medium Format cameras are not as good as AF on your average 35mm (my experience with the Mamiya 645AF. Please correct me if I am wrong).
2) Medium Format photography is largely a manual focus space and some of the best lenses and cameras will be available in manual focus only.

Well you are most probably right I guess, since I only have and use Pentax 645N before only, so no experience with other system and lens.
Just a beginner and learning from others and surfing the net.
But I read review for the AF 150mm f/2.8 lens, most people say it's the same or even better than the MF 150mm f/3.5 version, and I like a bigger aperture, since I use this camera mainly for handheld outdoor/street shoots, not for studio currently.

i'm actually pretty confused by the variants of the mamiya 645 and 67 around. the price seems to differ so much. seems like one can't get the 645 afd ii just for shooting film right? cos cathay is offering it free with a purchase of the digital back.
