I am researching the Canon TS-E 17mm f4 lens to use for architecture. I would be interested to get some feedback from anyone using this lens with either the Metabones or Sigma adapters on either an A7ii or A7Rii body.
Are there any functional issues affecting manual focus particularly focus peaking and focus assist magnification?
Is there any loss of sharpness?
Does auto exposure work correctly?
I would really appreciate hearing from people with first hand experience of using this lens with either of these adapters.
I am considering purchasing the Sigma 12-24mm f/4 and 35 1.4 DG HSM Art Lens for use on my Sony A7RII.
Any thoughts on purchasing Canon version and using Metabones adapter vs Sigma version with Sigma MC-11 adapter?
I have used the Metabones/Canon combination with my Canon L lenses.
Any one with experience using the Sigma/Sigma MC-11?
I am thinking of selling my set of Canon 16-35L 1.2II, 24-70L 2.8II, 50L 1.2, and 85L 1.2II lenses.
I have an A6000. For the past couple of days I have been searching the web for a Nikon F to E-mount full function adapter (AF, Exposure, etc.). I see one for the A6300. Is the A6000 so different that they cant make them compatible?
In my latest Video i´m showing you that Face Detect AF is also working with Canon Mount lenses on the Sony A7II with affordable Adapters from Viltrox and Fotga and not just the Sigma MC-11 Adapter. This could be something that you probably didn´t know. Get some chips and beer and have a look! http://www.dsphotoblog.com/?p=1425
I have now had the 70-400 and the LA-EA4 adapter for more than two months and have managed to cope with erratic focusing on garden birds somehow or other. One great thing using this adapter is that the spot focusing is much smaller than the standard one and let's you pinpoint be birds head more precisely and that I love. With the standard 70-200 f4 I could focus much quicker, but many times it either focused on a branch or the legs and body, leaving the head and eyes out of focus.
Lately however I've seen many comments about how much better the simpler LA-EA3 works with the newish A7RII, since it used all the more than 300 focus points plus other benefits that the camera could use on these lenses. The thing is I purchased the EA3 and tried it as soon as I laid my hands on it. Shooting garden birds from a feeder and at 400 mm (which is what I mostly do), and at about 5 m (16 feet) distance, I immediately noticed that focusing was much harder, sluggish and the lens kept hunting backwards and forwards most of the time. I have the camera set for obvious reasons at spot focus small, so I guess the 300 or so remaining focus points do nothing to help me focus, so I asked myself what was the point.... I then tried all sorts of settings to see if I could improve the focusing, even trying phase and contrast detect (contrast being a NO-NO), so now I find myself at a crossroads where I' wondering if I should return the EA3 or try and follow your suggestions on how to improve the focus with it. One thing is VERY clear; if I reinstall the LA-EA4, in the case I'm explaining here, it seems almost instant focus compared to the EA3.
What do you suggest I do? I only have this zoom lens that fits both my adapters, since all my other lenses are FE mount and right now I have run out of ideas.... Have read all that Brian Smith says about adapters and was one of the main reasons for making this purchase (http://briansmith.com/sony-a7-a7r-lens-mount-adapters/)
