250mm Lens for Hasselblad: which one is sharper?
kivivuori replied to kaugu_ciems's topic in Medium Format
If you have an opportunity to test various lenses, make sure that you will use 2-3 different film backs. Simply because lenses are good or excellent but film backs may vary or film pressure plates need adjustment. -
".... digital where it is impossible to compare the size of the real life object with the size of the image..." You know exactly the size of the sensor which simply means that nothing changes from 35 mm film if you use camera with FF-senor. If you use Nikon, Canon, Sony DX (APS-C) or other maller formats cameras and use the same lens you just have to change fron sensor distance accordingly to get 1:1 magnification. See sensor details Diagonal (mm) Width (mm) Height (mm) Area (mm²) Stops (area) Crop factor here: https://en.wikipedia.org/wiki/Image_sensor_format

Much better than I thought. I´m using it with D5300 (24 MP, no anti-aliasing filter).

RX 1 camera or Loxia 35mm2 on A7ll?
kivivuori replied to imagesbymonroe's topic in Mirrorless Digital Cameras
I`ve used Leica Q which also is a "pocket size" FF-camera but with outstanding 28mm fixed lens. It actually looks like a pocket camera which is extremely useful when you`re shooting in metro, bars, restaurants, late in the evenings, etc. Nobody pays attention what you`re doing :) -
I wrote my humble opinion. Nothing more, nothing less... And nothing to do with your earlier comments. BR Esa

I like this. This is modern, easy to use, very straightforward and first of all now members can send bigger images.

I love my IIIC (big C). Wonderful Rodenstock f:2/50mm Retina Heligon C lens and large viewfinder with three view frames. It`s bright and easy to use also with spectacles.

<p>My vote goes for 50mm f/2 K (Nov 1974 - 1977) and same lens AI-version (Mar 1977 - Jan 1979).<br />Those lenses have charcater :)<br /><br />BR<br /><br />Esa Kivivuori <br />Finland</p><div></div>

Anyone still use Nikkor-S/N/H Auto lens series?
kivivuori replied to iosif_astrukov's topic in Nikon

grain of kodak Tmax 100, looks when scanned
kivivuori replied to dirk_dom1's topic in Black & White Practice
<p>Hi,<br /><br />To me those examples look like "T-Max 1600" than T-max 100...<br /><br />I´m convinced that you should try drum scanning 8000 dpi or Imagon at least once to see the real difference.<br /><br />Best regards,<br /><br />Esa Kivivuori<br />Finland</p> -
<p>I`m just wondering how you can separate two black lines from each other unless there is some color between them ;)<br /><br />It´s obvious that one "line" consist two lines. Therefore I prefer <strong>lp / mm</strong>.<br /><br />BR<br /><br />Esa Kivivuori</p>

<p>I prefer 50 mm lens in vertical position. You have to take more pictures but you`ll get also more forground compared to horizontal position. <br /><br />It`s also good to remember that the nodal point can be found in front of the lens in some cases.</p>
