Wasn't snowing, and a little warmer today, so I walked over the little cemetery across the street from my house (nice peaceful spot where I do most of my camera testing) to try out the Ricoh GW3 0.75 conversion lens a bit more.
These are just straight out of the camera JPEG files with no corrections for distortion or vignetting, just presenting to give an idea of the changes in FoV
First we've got the RX1 at its native 35mm focal length (which based upon other 35's I've owned, seems to be a little wider than 35)
Next we've got the RX1 with the GW3, which I'd say equates to about a 25mm-ish actual FoV.
Finally, for an additional frame of reference with a known wider focal length, here is the 28mm (equiv) FoV from the Ricoh GR
I may post some samples of edges, etc., at full rez if there is really that much interest, but, that sort of thing always carries with it a lot of criticisms on methodology etc, so probably will leave it just to something for my own eyes and for me to evaluate based upon my own needs and IQ requirements.
I will say its pretty darn good, not just for a conversion lens, but for an actual native focal length lens, which is saying something. Very little distortion and it remains quite sharp basically across the entire frame. Rioch built one heck of a conversion lens.
Its of course a little difficult to evaluate between my known 28mm cameras like the RX100 and GR because of the differences in megapixels. The GR is just 16meg, so the 24meg RX1 can resolve a bit higher, in addition to being A LOT better at higher ISO than either the GR or the RX100.
During some informal testing late in the afternoon yesterday, I was shooting the RX1 at f8, w/ GW3, and that had be at ISO1600 or so. Still very clean, as RX1 users know, but the GR, shot natively at 28mm equiv, at F5.6 and ISO800 already started to get pretty noisy and really starts to lose detail, so the RX1 gave a marginally better image even taking into account the conversion lens.
Point of buying the GW3 is to give me 21mm equiv on the GR though, rather than turning the RX1 into a 25-ish mm camera that has to be shot at f8. That being said, it does look pretty handy to be able to just screw the GW3 quickly onto the RX1 and get a little more width for some shooting situations.
I don't know, at this point, if I would really suggest anyone buy a GW3 just for the RX1, but it works well, and if you often wish your RX1 was a little wider for landscapes, it could be worth trying out.
