    Disappointing results with 80 Mp High Res mode on E-M1 ii

    You may well be right. I processed the raw files again: I tried to lower the noise on the Sigma file, and increased the sharpness of the Olympus picture. This looks better. See SDIM7163-SHi3.jpg and P4230816_DxO3_39Mp.jpg on Index of /hires Also, P4230815_DxO3.jpg might be a bit sharper.

    Disappointing results with 80 Mp High Res mode on E-M1 ii

    I did not spend too much time with the sluggish Sigma Pro Photo. I put the maximum sharpness and lower noise reduction. I could probably do better. The tower is very rigid, considering its height. During the 1999 storm, the top of the tower (324 m with the antenna) moved only 13 cm (~ 5").

    Disappointing results with 80 Mp High Res mode on E-M1 ii

    Probably. FYI, I have a "MeFoto roadtrip" tripod. I never had any problem with long exposures at night (up to 60 s) but this is a different matter.

    This picture was just a test. I wanted to estimate the sharpness of the HiRes mode on the building and the tower.

    Disappointing results with 80 Mp High Res mode on E-M1 ii

    If the lens only resolved 20 Mp, then I'm afraid that no sensor trick would get more than 20 Mp in practice Right. The image is basically made of 32 Mp or 40 Mp in quincunx. The firmware interpolates data to add pixels. No, AFAIK, they increase the colour resolution by suppressing the effect...

    Yes, on a good tripod, with a 2 s delay. 1/500 s f/8 200 ISO, 12-35 @25 mm I developed the 80 Mp ORF file with DxO That's quite possible, because I just developed the 20 Mp ORI file, scaled it up at 40 Mp with GIMP, and the result does not look worse. I was told to switch the IBIS off, it...

    Disappointing results with 80 Mp High Res mode on E-M1 ii

    I quickly compared yesterday the High Res mode on the E-M1 ii with my SD Quattro. I had the Panasonic 12-35 f/2.8 with a 2A filter on the E-M1, and the 35 mm f/1.4 ART on the SDQ. The 39 Mp picture from the Sigma is definitely sharper than the 80 Mp from the E-M1 ii. What lens do you use for...

    Too many cameras...what would you do?

    Unless they give it to the concierge and run away. Or tell me that they don't have time to wait until I check that everything is OK. In any case, I'm protected by the law as long as I report a problem quickly to DHL (I checked)

    Too many cameras...what would you do?

    Great, it still have "a few" cameras. I'm waiting for an E-M1 Mark II (supposing that DHL did not destroy it as the last news from the tracking web site was: "The slightly damaged shipment is being repackaged")

    solution for determining GX7 shutter actuation

    Sigma SD Quattro

    I may have aggravated the problem by keeping noise reduction at the minimum on many images. The development process with SPP is definitely slow and after a while, I got bored and did not want to move yet another cursor and wait 30 s or more to see the resulting image.

    I'm badly affected by GAS and before Christmas, eBay tempted me with a 15% discount (max 100€). I'm weak :-( I bought a Sigma SD Quattro + 30 mm f/1.4 ART kit from a Spanish guy who was selling it after 50 shots. It came in its original box, in a mint condition. I'm still wondering if I am going...

    Nostalgy from the CCD look? I was wondering if buying a cheap and old E-500 on eBay was reasonable. E-410 are rarer and much more expensive. In what sense? MOS sensors have been so vilified...

    E3 Camera????

    Which one gave great colours? The E-3 (which had a MOS sensor) or the E-410 (CCD)? Edit: my mistake! The E-400 had a CCD, the E-410 had a MOS sensor.

    Oly 17 f1.8 is not as sharp as I expected...

    Well, the Panasonic 12-32 f/3.5-5.6 is an excellent lens, we already know that. At 17-18 mm, it is slightly sharper than the Olympus 17 mm f/1.8 when you compare the same apertures. But the maximum aperture of this small Panasonic zoom is f/4.2, i.e. 2.4 EV darker than the Olympus. "La netteté...

    Night shots

    I like it but there are minor defaults that could be fixed, I think: Horizon is slightly tilted. The chimneys on the left are distracting IMHO. You should reframe and cut a few centimetres on the left. The building and especially the yellow lights are overexposed. If your raw software allows...

    FourThirds glass worth investing in

    Nobody mentioned the ZD 7-14 f/4. I'm really amazed by the optical quality of this lens. I did not compare it to the 7-14 f/2.8 Pro, though. Note: although less luminous that the M4/3 f/2.8, the ZD f/4 is bigger.

    Some Night Photography

    The 12-40 f/2.8 is actually a bit sharper at f/2.8 than at f/11. Its optimal sharpness is between f/4 and f/5.6: Olympus 12-40mm f/2.8 Pro M.Zuiko Digital ED Review However, the difference is small, so there must be another explanation. Is your tripod stable enough?

    Olympus 7-14 f/4 (FourThirds)

    In the E-M1 or E-M5 MkII bodies, it is limited. However, a photo editing software can do more, but that's not really easy. I guess that Olympus designed something simple that could be used while framing the picture.

For whatever contractual reasons, Limal only ships...

    Olympus 7-14 f/4 (FourThirds)

    "Keystone correction" on E-M1 or E-M5 Mk II works but is limited to one axis. I mean that if you are in front of a building and tilted your camera vertically, then "keystone correction" will work. But if you were on the side, you will need to fix the distortion on the horizontal axis as well as...

    Water damage question OMD EM5/kit lens

    Make sure you dry the OM-D E-M5 thoroughly. It looks good now but some contacts may oxidise after a while (a month maybe?). Do not buy a new 14-42 kit lens, you will pay it too much. Find a used one (e.g. eBay) or buy something better. Note that the 12-50 is weatherproof but I doubt it would...

    Rumour of a PL 50-200 vs O 40-150 pro

    I bought a 50-200 SWD not long ago and did not use it yet seriously. I did a few trials, and it seems that it has strong purple fringing at 200 mm and full aperture; these chromatic aberrations really degrade sharpness. My E-M1 (Mk I) does not fix them. DxO Pro fixes them and restores the lens...

    Sony A99...why make an SLR with an EVF?

    Well, DSLR fans do not like EVFs so I suspect that the market for this camera is restricted. And sincerely, even if I love my 2.4 Mp EVFs (Sony A7, OM-D E-M1...), I have to admit that they are not as fine as a clear focusing screen. In very low light, I prefer the EVF but in daylight, 24x36...

    Sony A99...why make an SLR with an EVF?

    Odd, isn't it? They could have kept a SLR viewfinder. The Olympus E-10 used one too. IIRC, 2/3 of the light went to the sensor, and 1/3 to the viewfinder.

    I suppose that Sony designed this to reuse the technology that they had in their previous DSLR, especially the AF sensor. Well... It is as bulky as any other 24x36 DSLR, and it has a long flange distance, so you cannot adapt legacy lenses (or just a few ones) How is the EVF by the way? On...
