85 1.8 on 5DIII vs. 50 1.8II on 40D?

Hi guys,

I used to do some portrait/studio shoot with 50 1.8II on my old 40D.  Now that I have the 5DIII, my 50 1.2L is perhaps slightly too wide for my tastes.  I do have the 100 2.8L and also 70-200 2.8L IS, but the former is a bit too tight while the latter is a bit too heavy!

I'm thus considering getting an 85, but can't justify spending $2000 for the 1.2L since I don't do portraiture often enough.  But I'm want to know if the IQ that I'll get with 85 1.8 on 5DIII will be at least as good as what I used to get on my 40D with 50 1.8II.

I suppose it'll be hard finding someone who's used these exact combos, but perhaps someone can comment on the IQ of 85 1.8 on 5DIII?

Thanks!

Re: 85 1.8 on 5DIII vs. 50 1.8II on 40D?

The 85mm on FF will be slightly "longer" than a 50mm on a crop.

If you do wide apertures, where part of the scene is out of focus, you'll probably find the bokeh of the 85mm to be smoother than the 50mm f/1.8. It's also a much nicer looking and feeling lens. IMO the 50 f/1.8 feels like a toy.

Do you have the 70-200mm f/2.8 IS I or II? If you have the I, might consider getting the 85mm, but if you have the II... I have the 70-200mm IS II, and the 85mm f/1.8, and the only reason I use the 85mm is for non-studio work when I want to use the really wide apertures, usually for low-light shooting (e.g., bands on stage). The 70-200mm II is just so much sharper, and focus is so much faster and more accurate - even for the low-light situations, its AF performance actually makes up for its smaller aperture in many situations, especially when paired with the 5DIII's low light capabilities.

But in my experience, the older 70-200mm I doesn't deliver the same pop, and so you may be better with the 85mm.

Re: 85 1.8 on 5DIII vs. 50 1.8II on 40D?

Greetings,

I use the 85/F1.8 on a 5D2 all the time for head shots and other portrait photography.  I would like to justify the expense of the 85L but never have been able to do so. The CA can be easily fixed with DPP or Lightroom and out of frame lens flare controlled with a hood.

For a purely 'head shot' the F1.8 is almost to little DOF as with the eyes in focus the back of the head+hair (or even the ear for that matter) is OOF.

Wide open the F1.8 is said to be soft in the corners but I've never noticed for my framing or applications. I tend to shoot a little wide and crop after the fact anyway so corner performance is of little use to me. YMMV.

I have the mark II. However I will be using this portrait lens primarily out of studio.  I will have reflectors and maybe a strobe+umbrella, but probably will be relying on the lens wide open.

Re: 85 1.8 on 5DIII vs. 50 1.8II on 40D?

I never used a 40D, but the 7D has a similar look due to the crop factor and I loved the 50mm 1.8 on it. When I bought a 5D Mark III the first lens I bought specifically for it was the 85mm f/1.8 to try to get a similar feel to the 50mm on crop. I was pretty happy with the 85mm 1.8 for a long time. I recently bought the 85mm 1.2 and to be honest for most purposes the 85mm 1.8 is just as good. The main advantage of the 85mm is the very good sharpness you get at f/1.2-f/2, a level of sharpness not seen on any other lens at those apertures. But I still use the 85mm 1.8 a lot when I need fast autofocus and deeper focus.

Here's a couple of shots with the 85mm 1.8 on the 5D Mark III. I highly recommend it if you're getting into portraits.

Nice isolation, particularly pic 3.

The 85 1.8 on 5DIII will be significantly better

I've got an 85 1.8 on a 5DII.

It's fairly sharp wide open (sharper than the 50) and as sharp as you'd want for portraits. Better contrast than the 50 1.8 wide open and a little better in the corners.

As someone else mentioned you get more than enough subject isolation with the 85 wide open on a full frame. I'm not wanting for 1.4 let alone 1.2 when using it.

I also already have the 50 1.2L / 100 2.8L / 70-200 2.8L IS II

Theoretically, I could use a combination of these lenses to cover whatever photoshoot that I might want to do.  Also, would the 85 1.8 really be optically better (since it's a prime) than, say, my 70-200 2.8L IS II?  Leaving aside the concern that the latter might be unwieldy, optically I think it is unmatched by the 85?

The 85 obviously gives you 1.8 which the 70-200 doesn't but if you are happy with the subject isolation at 2.8 then the 70-200 will be be sharper in the corners than the 85 at 2.8 and about the same in the centre.

The 70-200 doesn't (apparently) have the nicest Bokeh so the 85 might be nicer in that department (I haven't any complaints) but again if you like it the 70-200's boken that there is no real reason to get the 85.

Unless you have a bad copy of the 70-200 2.8L IS II, that lens blows away the 85mm f/1.8. I wouldn't say the same thing about version I of the 70-200mm, but the 85mm has rarely left my bag since I got the 70-200mm.

The 85mm may have smoother bokeh, but that depends on the situation going on in the background. As far as the sharpness and detail in the in-focus areas, the 70-200mm blows the 85mm out of the water most of the time. It's also faster and more accurate in autofocus.

I get the 85mm when I want even shallower DOF (though I can get plenty of that with the 70-200mm, so I rarely use the 85mm for that reason alone), or I'm doing really low-light photography.

Re: The 85 1.8 on 5DIII will be significantly better

Thanks for all the replies, everyone.  I guess I'll save my money and just "make do" with the lenses that I already have

Given my current lineup, I think it's a safe choice, no?

24-105 4L

50 1.2L

100 2.8L IS

70-200 2.8L IS II

I'll do the photoshoots with them for now and see if I really miss having an 85 prime and its 1.8 aperture.

Thanks again!

The IQ of 85mm F1.8 is really very good. I have used it with my 5DII. The best result is around F5.6. Despite it does not have circular aperture, the bokeh is still very pleasant.
