  • DX crop mode of the Z7 gives you 20 Mpix. The Z5/Z6 DX crop gives you slightly less Mpix than your D90 with 12 Mpix. 12 Mpix is pretty OK for most slides, it already begins to show  the "grain" ...
  • I use both formats. Planning a trip to Zermatt next week, where I have to transfer all my apparel and gear for 2 weeks from car to train and then again to taxi, I really wonder on how many ...
  • Sure this is a timeless great image; Dramatic  moment caught. Excellent scene giving context with mast, building and trees. Great composition. But also mastery of challenging technical details: ...
  • Your full size image is quite interesting. It shows that the D7500  jpg engine judiciously  trades in image resolution to reduce noise. The high contrast metal frame of the glasses, and especially ...
  • I agree with a previous poster, image content and composition make or break a great picture. I see in your previous gear, that you owned a D7200. Hope you still have it. With its 24 Mpix and newer ...
  • You are planning for a system change, to get really FX image quality. This means getting a good camera + good lenses. It will sum up, if you got the money, ultimately your heirs will have paid for ...
  • so you managed to install mtf_mapper and did get results. I assume these numbers were read directly from the mtf_mapper output. I pre-process the raw file and crop to my chosen region of interest, ...
  • I do not see that bleed-halo with your test image on my MacBook retina 15" nor on my EIZO 3.8k graphics monitor. You might want to dig into MTF using the free mtfmapper, to establish what your lens ...
  • Replied in blade test
    your metal object got you near a serious MTF blade test: You could use a backlit razor blade as target, and then analyze a section of the blade edge using mtf_mapper.  Considering the tiny DoF, you ...
  • yeah, sorry. We did not have funding to pay 2000$ to make it open access. Some of the ideas are in the full field MTF thread .  If you are going to spend time and money for doing measurements, it ...
  • Replied in Sigma's take ?
    Your model convinces me that Sigma fp L actually uses an AA filter. Displacement 0.66 pix ? Your Z7 has no AA and a reduced pixel aperture moreover. Do you have an obvious example in a natural ...
  • The D810 makes up about half of the 1 stop reduction in lens speed, compared to 24-70 f/28, by its higher full-well capacity and higher quantum efficiency. The longer max focal length of 120mm ...
  • Replied in Sigma's take ?
    Their latest cameras, the fp , use Baye r (full frame, 61Mpix, BSI) sensors. The page does not say no AA filter, but I assume it follows current trends in having no AA. Such a camera should show ...
  • The small and lightweight AI 20mm f/3.5 sometimes goes to the top: Ai 20mm f/3.5 at f/11 on D800 It is very flare resistant and quite sharp in the center. It is not as sharp across the field as a ...
  • Replied in Tele for D5100
    a good AF-S 70-300mm f/4.5-5.6 G VR , used from ebay, is the best choice in your case. Up to about 200mm it is a very sharp lens with even sharpness across the field. At its long end sharpness ...
  • 16 mm (24mm FF equivalent) is a surprising lot wider than 18 mm.  I would say that even wider than 16mm gets you into ultra-wide angle photography. That can also be appealing and interesting, but ...
  • The 24-120 is not a good match as a DX walk around lens, it is meant for FX. As DX, it is not wide  enough at its wide end and it is a relatively heavy lens for a DX walk around lens. So if your ...
  • This is not a lens . it is a slide or alternatively a film holder. It requires a lens like the 40mm Micro Nikkor or the 60mm Micro nikkor. A friend bounght an ES-2 + a 40mm Micro Nikkor lens  about ...
  • Replied in Copying Stand
    Hope it is not too late about the scrapped enlarger head. It is worth to retrieve it. It contains an engineered lighting system to back illuminate things like negative films, or slides ... or an ...
  • Replied in Copying Stand
    Kaiser RS1 looks excellent. It may be robust enough that you can simply click right at the camera with due care, as I often do. How about illumination ? I use two LED panels in my basement, or ...
