• UPDATE



    The forum will be moving to a new domain in the near future (canonrumorsforum.com). I have turned off "read-only", but I will only leave the two forum nodes you see active for the time being.

    I don't know at this time how quickly the change will happen, but that will move at a good pace I am sure.

Is There a Definitive 85 to Get?

An 85mm lens on my 6D might be what I'll need most of the time for stage performances. My son just made the cut on one of the best high school jazz bands in the country. Yes, his life's over until May, but he's good with it.
There is a lot of metal so CA is maybe a top concern. I do shoot in RAW, but for some reason whenever I see purple where it shouldn't be I start screaming at my computer. Not sure why.
Thanks for any "best" recommendations although it's possible, I guess, that there's no terribly wrong answer.
 
The Sigma 85/1.4 Art appears to have the lowest axial CA (purple/green fringing).

Personally, I have the EF 85/1.2L II, but I expect I'll be swapping that for the EF 85/1.4L IS in the very near future.

Cory,

if you are after the best CA control in 85mm wide prime with reliable low light AF and a palatable price, then I would strongly advise you to give the Tamron 85 F1.8 VC a very good and long look.
CA control of the lens is much much better than on Sigma 85 Art wide open. better AF speed in low light and arguably a slightly better consistency.
it is a cheaper option as well. from experience, you can perfectly get away shooting at F1.8 rather than at F1.4 with your 6D body. focus and recompose is the only available focusing technique on 6D as well. therefore at F1.8 you chances of getting in focus image on 6D body is much higher. I would say, aim for F2.8 if you really can afford to stop down that much and if you can, then 70 -200 F2.8 IS is what I would use instead for flexibility of zoom lens.

Thanks. I do normally try to stay at 2.8 or smaller (aperture) so that might be a very good call (for all the reasons mentioned). Much appreciated.

I'd love a few more 85 (with AF) choices. You have the $300 model which I've owned and won't go back, the Old L and new L which are out of my budget for that particular lens and the Tammy which according to Bryan, I should not buy at 749. Why not extend the 24/28/35 IS lineup to 50 and 85? $550-650 and take my money

If you don't mind the lack of IS, heavy weight, considerable bulk and uncommon 86mm filter thread size, the Sigma 85/1.4 Art is probably the one to get.

Read Brian Carnathan's very balanced review:
https://www.the-digital-picture.com/Reviews/Sigma-85mm-f-1.4-DG-HSM-Art-Lens.aspx

Carnathan also has reviews of most of the other 85's on the market for a useful, independent viewpoint. This should be your go-to lens review site.

pwp,

in regards to 86mm filters. I was referred to the Gobe filters by a photog who is associated with the business here in Australia. I was sceptical initially until I had a chance to run sharpness, reflectance and aberration tests with the following filter and my own lens and camera:

https://mygobe.com/au/shop/lens-filters/uv-filters/gobe-uv-86mm-schott-mrc-16-layer-filter.html

there are 3 versions:

Premium - Gobe UV 86mm SCHOTT MRC 16-Layer Filter << I have got this model.
Pro - Gobe UV 86mm MRC 16-Layer Filter (Japanese glass)
Standard - Gobe UV 86mm MRC 12-Layer Filter

at A$58 for a good quality 86mm UV filter the product is a steal. They sell on Amazon as well. Just for your information.

The Tarmron is nice but having used it for more than a year professionally at weddings and events I can say that low light AF performance is the bottleneck here. Low CA for sure.

The Sigma could be a good choice, very sharp but do check your copy has good AF. Currently I’m in possession of the new 85 IS and I think it’s great, very sharp and the focus is among the best I’ve ever seen in a Canon lens.

I'd never heard of Schott filters. Thanks, I'll bookmark their site. Great value if the quality is there.

another vote for the Tamron 85mm 1.8 I shoot performance, music and dance with a 6D (and cough Sony) with it typically at 1.8 to 2.8 and love it.
last shoot from the weekend, most shot open, wide shots at the end are from the Sony with Sigma 30mm 1.4 (these are at 3200)

Just got Sigma 85mm f/1.4 EX DG HSM Lens (one before Art). Testing out on moving target after AFMA on Canon 70D. This is 50% crop at f1.4 1/2500th iso500 on a moving dog with low contrast using AI Servo. Not every shot is in focus. Some soft and some usable but not tack sharp. Only paid £300 and loving it especially on the 6D 8)
