Fun with NEX-7

This subject brings out the best in your snaps :)

Keith, Thank you.

I was torn between the ancient Biotar 75/1.5 or the newer Fujinon-TV 75/1.8 (a Biotar clone)- chose the later.


NEX-7, Fujinon-TV 75/1.8

Mikal, It is a c-mount lens made for CCTV use. My sample is not the latest iteration but one before.

Is it a good lens for NEX? I can't tell. I only have the NEX-7.

If you want sharp pictures with very high clarity, the E 50/1.8 can't be beat. If you can deal with spending time to make a correct lens profile (to get the proper WB), can put up with flare (the 75/1.8 is single coated and needs a proper hood), rather odd shaped diaphram and like very smooth bokeh, then the 75/1.8 is a good lens. It is tiny and is just as long as (about 1cm longer)the E primes that are made with glass elements. Most likely, this lens will see more action on my future Fuji X Pro 1 than the NEX-7. :) Hope this helps.

Vivek, yes it helps. Thank you. Still deciding between the 5n and the 7. I already have an M 50/1.4 pre ASPH lux so I think I am ok on the 50mm end.

A few taken today with the NEX7 and Contax G 28mm f/2.8 Biogon. Processed in C1. Last is a stitch of two images and converted to B&W in SE2Pro.

Carl - looks like C1 takes care of the Nex 7/Biogon problem really well! How do you integrate your workflow using C1 with LR4 - is your library in LR4?

Keith,

I keep my library in LR4, including original raws and exports from C1. I really like shooting with the little 28 biogon and C1 cleans up the magenta cast nicely. Corner and edge distortion is not a big issue on the NEX7 and even less so on the 5N with the biogon. I'm looking forward to working with the Contax G lenses on the Fuji XP1 and perhaps even the Ricoh GXR-M with a converted lens.

Carl, Thanks for the images and the processing routine details. I will have to try that.

I found the tiny 2.5cm f/4 W-Nikkor-C and the ex Soviet Orion-15 28/6, both LTM lenses, have good corner sharpness wide open. Both are Topogon clones (as symmetrical as a lens can get other than a singlet). Time to press them to service, now that I found a good LTM adapter. :)

Thanks Vivek. Which LTM adapter do you have?

Scho, I tried my Biogon 28 on my NEX 7, and got colour shift. Do you clean up your shots (excellent, BTW!) in Cornerfix?

I used a LCC profile generated in C1 to remove the color shift. Similar process to CornerFix, but does not require dng file format conversion.

A muscle wood log washed up on the creek bank. NEX7 with Contax G 45mm f/2 Planar. Shot at f/8 in shutter priority mode. I was having problems with camera movement at the default 1/60 sec using aperture priority mode and AUTO ISO and do wish Sony would implement user enabled min shutter speed for AUTO ISO.

You might consider using S mode with autoiso, so you can set the shutter yourself. Works great with manual lenses.

Thank Douglas. That is the way I've been shooting in situations where I know that AUTO-ISO with A mode will fail (ie. default to 1/60 sec). Sony should update firmware to allow setting a minimum acceptable shutter speed when using AUTO-ISO.
