Just got my Samyang 14mm f2.8 back from the repair shop. Works like a charm now. Did´nt notise the body was crooked when i bought it, the right side of the image was wery unsharp. Not anymore!

It feels right, but is so wrong. A battery grip and the huge Samyang 14mm on the A7r. Got a few more adjustments to do on the Fotga EOS adapter, then it will take 2 58mm B+W filter, and maybe a slim polarizer! 🙂 Thats was the main problem with the 14mm when i had it for the Canon, that it didnt take filters. A7 for president! (When i think about it, that would an alot more valid option then some others :P)

Refurbishing a Kiev Jupiter 9 85mm f2

kiev-2 kiev-1

Sony a7r + Nokton 35mm f1.2 II

Took my Jupiter 9 apart today and greesed it up. And i got it back together aswell 🙂 Suprisingly small amounts of cursewords and problems! Seems to work fine now, we´ll see how it performs when the ebay adapter arrives for my a7.

Removed a couple of fabric peaces that where counteracting there intended use. Decrease friction. So without the cloth peaces, there is some play but my guess is thats nothing to worry about 😛

Full frame -> Mft comparison. (Omg) ;) Sony a7r vs Em5 (with nokton)

compare-1 compare-2 compare-3 compare-4 compare-5 compare-6 compare-7 compare-8 Crop Crop-1 Crop-2

Most people, or atleast the slightly neerdier ones have a pretty strong opinion about weather this is “possible” or not. Comparing Mft to FF i mean. But here i go again.

The mindblowing detail of the 36mpix A7r sensor isn´t really there. When i sharpen pictures i look at them 100% so often it feels like the detail and sharpness is at best on pair with my Mft setup with Em5 and Noktons.

But when i zoom out, and see the “bigger picture” i realize thats not really the case. The A7r delivers “better” pictures for sure. Will i ever “use” the 36mpix and the “better” image quality? With 92.1 – 99.3% certainty, NO.

But thats not the reason i bought the full frame A7r either. The reason was mostly my Em5 is breaking apart, the shorter DOF, FF Bokeh and dynamic range.

At 100% the sharpness of the Noktons i had with my Em5 is on pair With my current set up. (But the A7r is 36pix so its actually alot less detail in the mft shots)

My Minolta MC 50mm f1.4 + A7r is a lighter package and delivers alot of “Bokeh for the buck” with great dynamic range.

But lets focus on the reasons i bought the A7r, DOF, Bokeh and Dynamic range, and i think this is where full frame is still in a league of its own. Sharpness and on many levels ISO is really good on the MFT system. Somehow the Em5, eventhough the pictures are noiser then lets say a Canon 5d mkii, there is more detail in the Em5 picture.

If one would do the math, Noktons f0.95 is not that far behind, thats about f1.9 on full frame, but the separation and pop i get with f1.4 on my A7r is really where it prevails. Bokeh is alot nicer on the lenses i have bought so far. Its not as “harsh” (now im beeng a little picky here, the Nokton bokeh is great) as the Noktons some times are.

DOF feels alot shorter even if the background seems blurred out to the same or similar extent the subject(s) seem to pop more.

And dynamic range, i still havent gotten used to it, alot of the times i push the trigger and think, “Thats gonna be blown out” but its not. I still cant belive how good on that regard it is, the dynamic range is a world of difference.

And one more great thing, Focus peaking! I had no ( or wery little issue ) with manual focus on my Em5 but now, with focus peaking. Why would anyone want AF? 😛 Siriously though, AF is great of course, but focus peaking is aswell!

I have an appointment in 30min so i gotto go, i´ll read through this later. Sorry if  the spelling is worse then usual.

Nokton 42.5mm f0.95 crop and Chromatic Aberration remove

So yeah, this is as bad as it gets, sun high in the sky,blue bird, white reflective transperent cup, reflective background. Everything in this pic produce CA. This would be one of those times you should stop down to get rid of the CA , but who can resist the f0.95 right? :).

It took a couple of minutes to correct most of the purple CA in Photoshop, 1st pic is a corrected version and the 2nd is a 100% crop.

3rd pic is a non corrected and the 4th is a 100% crop of that one.

I usually dont bother/care about CA but in this case it totaly ruined the picture, and its not that big of a deal to correct when it gets bad.

mostly all i need to do (in my opinion) is decrease the saturation of purple in Lightroom and the worst is gone, and when it all turns to shit, i´ll use PS for a couple of minutes.

If you dont know how, just check Youtube.

Finaly!

Finally i can post stuff again! All the pics are shot with the Nokton 17.5mm and Em-5.

There is some CA in most of the pics, mostly around the white edges in the images.

I reduced the highlights in the shots above in LR didnt try harder then that to remove the CA, alot goes away when i do that. Not all but most.

Dont usually bother more than that.
