    Luiz, you pushed this file over its exposure limit... color cast and banding are all over the sky, even for this small web size. Exposure latitude a weak spot of a Foveon sensor.

    Thanks for your note, Malina. It seems to me that DP1 is more sensitive than DP2 in appearing banding noise in the dark blue sky. The sky had gotten too dark and I pulled the X3 Fill Light slider a bit ... Now in a new attempt to reduce the banding noise. Improved a bit ...
    I agree the foveon sensor is very limited in dynamic range.

    Sigma DP1 Merrill Review

    I stumbled upon a very informative DP1M review from a well regarded Polish resource that I haven't seen mentioned before. It's in Polish only, but Google Translate can help us: https://translate.google.com/transla...6test_ap%3D227

    Though I'm quite familiar with DP1M 19mm lens optical performance from my own tests, it was interesting to learn quantitative measurements of some aberrations. Especially important for me - optical distortion, turns out to be ~-1.5%. That is quite impressive for a 75 FOV APS-C lens. Not all FF 28mm primes surpass this correction level. Other compacts with 75 FOV (Coolpix A, GR, X70) rely on baked in RAW lens distortion correction that I often find disruptive for environmental portraits. DP1M lens isn't perfect, but under right circumstances (sufficient light, iso 100, f4-5.6) this camera can deliver me striking shots with finest detail and rich color sans apparent aberrations that no other 75 FOV compact can match yet.

    The color of the glass structure seems to be out of adobeRGB gamut These days we complain about insufficiency of 12-bit ADC, when our monitors just might have 10-bit with 100% adobeRGB color accuracy at best.

    DP1M & Ricoh GR wide angle adapter (21mm equivalent field of view). A reasonable alternative to the DPO Q, if Merrill sensor, form factor and faster lens are preferred.

    Please share exactly what pieces are needed. The specific lens, needed adapters?
    I'd love to put one of these on my DP 1 Merrill.

    Thanks in advance,

    Re: Sigma DP1 Merrill Shots

    All you need is: "Ricoh GW-3 21mm Wide-Angle Conversion Lens B&H # RIGW3WCL MFR # 175780".
    It screws directly onto the DP1M or DP2M lens and works nicely with both. No adapter or step up/down rings are necessary.

    Re: Sigma DP1 Merrill Shots

    I read up on this combo (DP1M + GW-3), but corner performance looked not good enough to me. Enough that I would usually want to crop in from 21mm unless non-detail areas occupy the corners (blank sky, blurred clouds, etc). Depends on your tolerance for detail loss, but we are talking about foveon here, I think most people will be picky I think if possible, stitching is a better wide angle solution. Just my take though, maybe retow has a different experience or tips to use this combo.
