Which is the 35mm equal fora 2.8 lens

I know theres alot of threads about which lens is the better for

this or the = to, etc.. but my question is a little different. In

35mm , I use a 105 2.8 macro, for portraits and just about anything

with a face, and its perfect for me- Im going to be buyign a Bronica

Etrsi stsyem soon , and Im looking at either a 150 or a 200mm lens,

but Im not sure at what to look for in the Apeture range... 2,8 is

the magic # for 35 mm, whats a good one for MF if i want to achieve

shallow DOF?

You'll find little in MF lenses that are faster then 2.8. Go with a good 200mm.

I think it depends on a relative distance between the subject and background. 150 f 5.6 gives a nice out of focus blur in many cases when shooting 6x6 portraits. regards

James, I have the ETRSi and I split the difference and went with the 180mm, it focus's closer than the 200mm. The 150's have a good rep, but I also wanted a little more space between me and the subject. Works good for other things also.

I prefer the 150 because I can often find myself shooting in less spacious rooms. It's a trade off really. If you know that you will only be shooting in large areas, then the 200mm will be great, but, if you see yourself shooting in smaller rooms or areas, you may wnat to consider the 150

For 6x6 portraits, the perfect combo for me is usually 135mm with a 15mm extension tube, and I'm usually around f:5.6 or 8 to get enough DOF so that the subject can move and sit comfortably without the eyes going out of focus. I have a 200mm, but for whatever reason I think the particular 135mm I have produces a smoother look for portraits.

The Bronica "portrait" lens is the 135mm f/4. You don't see it advertised much (it looks like poor value compared to the 150mm f/3.5) but it can focus a lot closer and is very sharp.

I use a 150mm f/2.8 F lens with my Hasselblad 2000FC/M. Most often I use it at f/5.6 for reasons listed before. There's not much DOF at f/2.8.

James,

 

Possibly try and rent what your looking to buy - not easy I know with the Bronica system.

 

It's only really by seeing what suits your style of shooting that you'll find what you ultimately want to go with.

 

After shooting with a Canon EOS 85mm f1.8 I've got to say that medium format has not dissapointed with it's control over DOF. I've got an ETRSi and the 150 f3.5 older (and well regarded) MC lens. As already pointed out it focusses at around 5 and a half feet as a minimum (without extension tubes). I'm wary of shooting my kids at f4 or below because the depth of field can be so shallow that I'll struggle to keep both of them in focus - or even one of them.
