50mm Conversion Lens for Ricoh GR

What I wouldn't give for one. What would you give for one?

I know only a scant bit about lens construction, but if they could manufacture a conversion lens that mounts to the barrel adapter (ala the 21mm conversion) and gets the focal length out to something approaching 50mm, I can tell you right now I'd buy it yesterday, and my K-3 would start writing letters and leaving voicemails for me, asking if it was something it said or did wrong.

Just went on a great walk-around with the GR and the 21wide in tow.... adding a conversion the other direction would've made me not come home.

One is coming for the X100/s, would make sense for Ricoh to respond with something similar...

I heard that. And yes it sure would make sense.The crop modes certainly are appreciated as are the very frequent firmware updates, but an actual conversion would be stellar, particularly considering the crop modes exist already.

You could mount the Ricoh GT-1 1.43x tele conversion lens to the GH-3 with a step down ring. So the 35mm crop mode would give you a 50mm FoV. But keep in mind the adapter creates some pretty soft corners. Possibly from field curvature.

I hadn't even considered that - I had a GRDIII which I heard they worked horribly on so had entirely forgotten about the GT-1. I just grabbed up a used one and will try it out. Soft corners can be fun and don't bother me, particularly at longer lenghts, provided the center is sharp.
Thanks for the IDEA! I'll post what happens.

Eureka!

Heh, I'm guessing you're the one that bought the used one I was watching. I even thought about buying it before I told you about it. But I've got other cameras for shooting at 50mm equivalent. :-)

Well, the GT-1 arrived a couple days ago and I've been having a bit of fun with it but only for a short while. Weather has been rainy here the past two days but will get out it. First impressions are just as I thought - the corners have extreme softness at wider apertures, but nonetheless it's a fun combo and can be used to great effect. Focusing seems just fine though the minimum distance seems reduced before needing to flip it to macro. All in all at the onset it really like the combo. At 47mm, though the files are certainly smaller, it's an impressive bit of zoom for this thing. I should also note that the GT-1 is significantly smaller and lighter than the GW-3 and the handling of the cam with it feels really good, and not quite so front heavy as the wide-converter can feel at times.
I'll get some images up when I get some time.

Here's a quick example shot... This was in 35mm crop mode which gives pretty much true 50mm(ish... I won't do the math) reach. You can see how soft the corners are but for portraits and anything framed center, it's pretty neat... soft focused filter sort of look, but the center is bang-on sharp still. Cross posting in the other thread.

Fuji just announced a 1.4x adapter for the X100(s) cameras. That should theoretically work on the GR with an adapter. It's called the TCL-X100 and does not yet have an expected price.

Looks rather large, but may be worth a look.

Does anyone know whether the Fuji Adapter works for sure on the GR?

I am thinking about getting the GR with the wide adapter to replace the DA15, and with a 50ish option it would give me almost everything I need

I'm not sure if it's even out yet. It's designed for adapting a different focal length lens, so it's iffy. Also, this review says the is some rather visible pincushion distortion.

I tryed a 2x made by canon with a 49-58 ring. The quality remains the same but you can see vignetting. I'm going to try the canon 1.4x. Should be similar to the Fuji 1.4x
