SK 150mm 2.8

Postby Marc_D » Wed Nov 23, 2016 8:35 am

Good morning.
I am new here and am actually waiting for an XF IQ3 100 that should arrive today with some lenses.
My question is about a specific focal lens and Phase One's offering: I initially ordered the SK 150mm 3.5 LS for portrait work, but the dealer ordered the newer SK 150mm 2.8 LS. I believe that he is trying to get me the best equipment possible, but the 2.8 is some one kilo heavier than the 3.5 and that's getting very heavy handheld.
I appreciate that I will have to use a tripod often, but so far in studio I have shot (Leica S) handheld, as I think that it looks more natural to the model.
I would be grateful if somebody could chime in about this and give me some views about the choice between the heavier vs lighter lens and as well about the 150mm focal length as a portrait lens with the XF system.
Thank you.

Marc

I have the f3.5 version precisely because it is so much lighter. I'm told that the edges on the 2.8 version are better, but for my use (wildlife, flowers etc) this is not important. I find the 3.5 to be very sharp.

My only concern would be the resolving power of the two lenses. You are putting it on a 100Mpix back, so the 2.8 might give you a little more detail. As the 2.8 is newer it might be more designed for the 100Mpix back, vs the 3.5. I would talk to your sales agent, and maybe see if you can try out both lenses.

I had the 150mm f/3.5 and it was a great all around lens. Small and light and easy to use in the field for landscape etc. I actually use the 150mm focal length a lot. More than I thought I would.

Got the 150mm f/2.8 and it is heavy. You may want to do lens curls daily for a while to get used to it. Seriously it is well balanced and with the large focus ring and brightness it is easy to focus with your fingers that hold the camera. If you focus using autofocus you should check the Focus Trim. At 10' your DOF is about .3 inches.

In the field it can be a handful. If you use filters you will have to go 105mm for screw on and 150mm filters if using front of the lens filters like Lee and Singh-Ray.

Good luck and happy shooting.

Thank you, that's useful.

I already have the 35mm, which has the same filter size I think, so that would be an advantage.
