Fast Primes On the Sony A7 – Sample Photos – EF 135mm f/2 and MC 50mm f/1.4 lenses

Minolta MX Rokkor-X PG F/1.4 50mm Lens

In this post I’m going to show you a few sample photos taken with the Sony A7 and the Canon EF 135mm f/2 L lens, and Minolta MC Rokkor-X 50mm f/1.4 lens.

I used the Metabones III lens adapter for the Canon EF lens and it worked pretty good although struggled with a few extremely shallow depth of field focus points. I helped it with manual focus and then it locked on no problem. This might be the best way to go when shooting wide open with such fast apertures, as it’s the hardest conditions possible for the camera to focus under. The high contrast out of focus backgrounds get focus on often or the camera for focus through what you’re trying to focus on like it never saw it.

I used my RainbowImaging lens adapter for the Minolta lens and it worked really well as expected. I did have an issue with the A7 though not allowing me to magnify zoom with the fully passive lens and lens adapter combo. The camera allowed me to shoot and everything else, so it’s probably an option in menu I missed.  It looks to be not available for some reason, but as I said I will get to the bottom of this one way or another.

 

Sony A7 w/ EF 135mm f/2 L Lens


I went with the EF 135mm f/2 L lens first because it was mounted to the Metabones III adapter and the Sony A7 already in my camera bag. Sorry for the lame snapshots, but I’ve been really jammed up the past few days, plus it’s freezing out and is dark when I get off work. I’ll find something cool for the review, but for now just a few test photos. I was about 5 feet from the sun sculpture for reference and shooting Raw quality.I developed these A7 raw files in Lightroom 5 and only added medium contrast with the curve tool and slight exposure adjustments. The ISO 100 is extremely clean and the colors and contrast with a quality lens is amazing!

The depth of field is so incredible narrow with this combo. I was about 6 meet or so from this sign when I took the frame for reference.

This lens is much wider than the 135mm and it feels like you are far from things when first switching to it. The focus was pretty easy with the Minolta lens even without the magnify zoom, because the focus peaking was clearly visible and can be trusted. You can see the peaking dots walk through the scene as you turn the focus ring to find the best spot. The vignette on the full frame A7 is much more pronounced than on the smaller sensor Nex-6. It looks like I applied a Vignette in Lightroom on these images, but I did not.

Closing Remarks:

That is it for now, but please feel free to comment and I will test these in the Lab if you are curious on how they perform 😉 I also tested the Sony A7 VS Nex-6 with the Canon 24-105mm f/4 L Lens in the Lab and I used 50mm for the full frame A7 and 32mm for the APS-C Nex-6, so the compositions were as close as possible. I still need to go through all the images when I get some time, so please check back tomorrow or the next day for more…

Thanks again for checking in and I’ll catch up with you all later,

Jay

  1. Really like your images and thanks for the review. I’m waiting for a delivery of the Rokkor 50mm 1.4 and should get it any time next week. I will try it on my Sony A7R although my wife may use it on her A6000 Am I right in assuming the vignetting is only wide oped at 1.4 and goes away when you stop down?

      Thanks Toni 😉 It will work awesome on both cameras as I have tested it a lot on my Nex-6 and some on the A6000 as well.

      The Vignette does mostly go away when you stop it down a bit and much less noticeable on the crop factor A6000 camera.

      I hope that helps and Lightroom or antoher program like it, can correct anything else if needed really easy!

      Jay
