85mm

i took some samples between 1.8 and 2.8 a couple of months ago, but i don't remember if i kept it :(

That would be the ones I'm primarily interested in, though 1.8 vs. 4.0 is also worth a look - I wonder if buying the 85/1.8 would make any significant difference to my 100L, and then of course there's the CA issue which is really minor on the 100L (on ff, crop has a bit more of it).

But I don't shoot like that so sold my 135L but kept the 85 1.8. It's very good value and flexible, producing a pleasing bokeh that's on a par with the 135L IMO.

Thanks - can you (or anyone) tell me how the 85/1.8 bokeh compares to the 100L?

The bokeh of the 100L is very plain and even to the point of being boring which makes sense on a macro lens, quite unlike my 70-300L with a much more vivid but not disturbing bokeh, though it's radial on the edges on ff which would be due to the small lens diameter (67mm) and large zoom range.

i do have the 100L macro which doesn't suffer from CA but it doesn't melt the background like the 85 1.8 :(

Are there samples anywhere for the background blur difference in comparable/same images? Since my fastest lens around this focal length currently is f2.8 I have no idea how large the difference is.

We do have a 100L at Building ~Panoramics but I haven't used it much, certainly not for shallow DOF shooting. In reality there is also very little depth of field difference. An 85 @1.8 @ 3.75 metres has a dof of 11 cms according to the Canon dof calculator. Assuming you'd be a little further off for the slightly longer lens, say 3 metres for the same framing dof is calculated at 15cms.

I believe the 85 1.8 was designed with little chromatic aberration correction to give a smooth out of focus blur, hence bad purple fringing, but in practice, as with so many other things I think you would be splitting hairs with the difference.

I'm using is a lot recently on ff because it's the only f2.8 lens I own, it has good/ok quality wide open, no CA and to mfd so it's very flexible... I know it cannot compete with real high-iq €2000+ primes, but on the other hand 85/135 sounds like a lot of duplication to me.

Hmmmyes, that's what I thought, and that's why I didn't buy it - thanks!

I've owned the 85/1.8 and currently own the 85/1.2L II.

If your goal is portraiture, but you can't deal with secondary spectrum/longitudinal chromatic aberration/magenta-green fringing/spherochromatism/etc., then I don't recommend either 85mm lens shot wide open. The 85L is much better once stopped down to f/2 or so, but at f/1.2, it's going to give wicked color fringing in areas of high contrast. With the 85/1.8, the fringing is still there as well.

The 135/2L is a better choice for avoiding this specific aberration, and the quality of blur is very, very nice. I would say that it's as good a portrait lens as the 85L. It's also more affordable. I decided it didn't fit in my lineup because of the other lenses I already own, but it is an extremely well-regarded lens, and in my opinion, for what you are looking for, I think it fits your criteria best.

What the 85L (and 50/1.2L) can do, however, is retain strong background blur while giving a wider angle of view than the 135L. That's why those lenses are so coveted--they are capable of giving a certain look that other lenses cannot match (but it takes a particular sort of composition to reveal it). The trick to using these ultra-fast aperture lenses with a lot of color fringing wide open is to shoot in conditions that are low-contrast, with few bright highlights. The 85L is not a lens that works well if shot wide open in direct sun.

Right, like a bride in a white dress on a sunny day... someone was showing off their collection of 85L wedding shots all shot at F/1.2 and oh dear, the dress did look interesting with a purple outline haha.

I have both; whilst (as everyone seems to agree in this thread) that the 85 1.8 does have CA issues, the quality of the blur is superior to the 100L wide open - mostly due to the wider aperture. The 85 has lovely bokeh. That said, the 100 does too, and can still very competently be used for portraits, however has better uses in other areas (ie macro!). The real winner is the 135, beats the 85 and the 100.

Hello :)

Here are my worries:
The 85L is adorable but i'd have to sell my kidney to buy it :D

so i'm stuck between the EF 85 1.8 and the Sigma 85 1.4

I have a 5D3

i've tested the 1.8, i had absolutely no problem in focusing at 1.8. The sharpness was ok and with a little help in post processing i'm quite satisfied!

The one thing i can't tolerate is the purple/green fringes. The ones that are blended in the bokeh are unfixable :(

I'm talking about head portraits mostly.
The 100L macro which i own, is fringless on that matter.

I was wondering if the Sigma is any better? I need to shot wide open and i don't know which one performs better or should i just stay with 100L 2.8.

phewwwww decisions decisions...

I have the 85/1.4 and it is great (the focus speed on the 1.8 is the fastest of the lot), that is, .... until I got to play with the 1.2 for a few weeks. I still like my 1.4, but everytime I use it I am still thinking about the 1.2 :)

Then again, one should be careful of using my logic, as I have borrowed the 200/2 for a couple of years, and that is a lens I can never afford (or at least if I want to keep my marriage), so the day that one have to go back, I will be content with my 70-200 2.8 II

Sell your kidney - okay just kidding! In all seriousness, though, the 100 2.8L is a great lens and the 85 1.8 is going to disappoint when shot wide open. I'd keep saving as there's nothing quite like the 85 1.2. I put off buying it for many years which was a huge mistake. It really is all that, at least for portraits, and if that's what you're shooting, keep the 100 2.8L, make money with it and save up for the 85 1.2.

The 135 is a great lens, too, especially for indoor sports, but for portraits, you're kind of restricted to headshots unless you have plenty of room to back up and indoors, that's frequently tough, and full lenght shots require a lot of distance.

I found that adjusting the micro focus (AFMA) with FoCal made a big difference in terms of both types of CA with all of my fast glass. Obviously it just applies to the in-focus areas, but for some reason, it seems to help overall.

That is a very good point, it's the OOF areas that exhibit the most CA and fringing, and keeping tack sharp focus on what's important to keep in focus (well, the most basic of rules in focus) then yeah, it's then up to choice of aperture and what sort of lighting one's in. I was just recently shooting with a Zeiss 85 wide open and I liked how it was sharp, but the CA in the bokeh was still there, not enough to be an issue though. As far as I know the only 85mm around at a reasonable price, and has near perfect bokeh creaminess and CA control is the Samyang/Rokinon 85mm, it is not sharp and of course all MF, but again it's very much affordable.

My advice, make due with the 100L until 2014. I would say it is HIGHLY likely we will see a refresh of the 85mm to go with the new 50mm f/1.8 IS that is being released.

i wanna thank you all for your advices. Finally a friend of mine sold me the EF 85mm 1.8 for a good price. I'm quite happy with it.

the 2014 might be a lens upgrade year for canon, but the economy isn't strong as it used to be. Canon lives in her own world on that matter, so probably a new 50mm and 85mm lenses will come out but the prices will be very high
like the new ones 24mm 2.8 IS, 28mm 2.8 IS and 35mm f/2 IS
