Passing on the GR IIIx

- Start date
p.s. it would be interesting to check other cameras with same sensor (i wouldn't know where else the same sensor is being used, but there must be plenty) and see if aspect ratio limitations are similar.

Yes I will checkconsidering that you're aiming for the maximum-sized 4:3 out of a 3:2 image, the answer is yes: all image software (including photoshop, lightroom etc) will let you batch convert your photos regardless of orientation: vertical or horizontal doesn't require different processing. you can automatically crop them to 4:3. please look for online tutorials: youtube etcNo i do not
ok but i need to check something first . Maybe you know the answer to that one
if i put crop marks on the lcd like you suggested, when i ask photoshop to crop with the 4:3 ratio , is it going to select exactly the same crop than the one i was seeing on the LCD ?
If this could work, I would get the GR3x first as 40mm is my favorite focal length for street photography
But I also need someone to confirm something for me how the AF lock would work if I assign to the FN button
I thought this would work like my SAF focus lock on the GR2 but someone told me that if I do assign it , it would only work for ONE picture .. meaning that the focus would not be locked until I press that button again.. in other words it would only lock for one image
As I mentioned many times before , there are several things that bug me on the GR3 but the 4.3 ratio and the af lock were the two deal breakers
so I would appreciate if a GR3 owner could let me know how the af lock works on the Gr3s when assigned to the FN button

RONDOM - it is probably the same sensor or very close derivative of the one used in the Sony 6400/6600. Those models do not give 4:3 aspect ratio, but do have 3:2,16:9,1:1. Sony are notorious for not having 4:3, only just implementing it finally in v4 of the a7R series, probably as a response to the popularity of the GFX with native 4:3.
The sensor used in the 6400/6600 is the imx271 :

At the moment i do not have access to the datasheet for full readout specs, but I also do not know the exact sensor or how ricoh spec requested it at their end.

I'm not sure that the sensor read out is the factor. We know that images cropped to 1:1 still have the full sensor read-out in the RAW. The crop is simply meta data.
Also, Ricoh have added the 35mm and 50mm crops modes. These must be specialised crop modes that are specific to Ricoh. Which makes me think that Ricoh are adding these crop modes in software. at some level. But perhaps not routines that are changeable at end-user firmware level.

very interesting. thank you, once again. i really enjoy encountering new and fresh info such as yours- in our small and lovely- and slightly dysfunctional echo chamber- this criticism includes me too
Tungsten - yes you could be right. But that would make ricoh decision to allow us to crop to 4:3 after the shot in review in camera, but not just let us see 4:3 at time of shooting incredibly bizarre. It is still a possibility that ricoh did not "purchase the right to use" a 4:3 aspect ratio even if the sensor can do it.

Certainly the decision (if it was a decision) was a weird one and limitations from the sensor would have explained it neatly.
But my theory is that the crop routines exist somewhere in rom at a lower level of services than the firmware touches. Hence they cannot reverse the decision.

I am pretty sure that there is no intellectual property to pay to add on the 4.3 ratio . Companies anxious to join the m43 system have to get an agreement but this is different matter connected to the sensor size but not to the image ratio
I note that most recent 35mm digital ILC from Canon and Sony tend to include that ratio . in 35mm cameras only Nikon and Leica refuse to do so

Hi Rondom
I am going to wait until I get the answer to my question about the focus lock button use when assigned to the FN button ;-)
someone already confirmed that the one press exposure M function can be assigned to one of the two arrows which can be changed to something else

(you may want to revive that thread, instead of continueing it here: maltmoose is very helpful)
also the manual:

(edit)
Still no AF and AE lock hold?
I went back to my GR3 expecting this to have been resolved by firmware, but no? On GR/2 the back button can be set to lock hold AF+AE, this is beneficial because once locked you get a distance scale that can be fine tuned with mf directly. Locking both stabilizes the exposure so can recompose...

Seems a little far-fetched to me, when we know the crop is not done in the sensor. And that as Ricoh apply their own 35 and 50mm in-camera crops, surely they can do the same with any ratio they like.

47mm crop was added during one of the firmware updates (GR- v.203)
so back to reeluff's theory:
when ricoh orders a sensor from sony, it specifies all the crop modes, aspect ratios they need..
and probably need to add several dollars for each customized property and they decided to skip some of them to lower the bill, and now they are stuck with it.
this sort of limitations may not have been at play in previous sony sensors which might explain the gr firmware update 2.03 back in 2013

Interesting. I forgot that.
As far as I am aware, yes ricoh would have to specify and pay an agreed licencing for a specific usage of the sensor. So, maybe ricoh only wanted 3:2 and 1:1 and that is all they paid for. Or maybe the sensor simply does not readout in 4:3. Or maybe like tungsten said it could be something further down the electronic pipeline that might/might not be able to do 4:3. Or maybe ricoh do not want us to have 4:3 at time of shot but tease us with post shot 4:3 crop abilities, for who knows what reason that would be.

Hi Rondom
Thank you for the info. I already had downloaded the manual where I did not find the info I was looking for. But the thread you indicated showed my what I feared
There is no AF lock hold when using the FN button. I saw Maltose suggest work arounds but frankly they are not quite the same
Silly me , I was already checking GR3X prices on the vendor sites that I usually buy from , thinking I could try your marking thing on a film protector for this camera but obviously this is not an option for me :-(. at least for now..
maybe one day Ricoh will fix this AF lock hold via firmware update if this is even possible
Thank you for your input anyway
Harold
I think we want each GR to be an improvement and be successful. A sleeper may mean it’s less likely to stay around

Not one single person I know outside of the camera forums ever knew Ricoh made cameras and certainly had never heard of the GR line.
I'm all in for improvements and I think Ricoh has seen moderate success, but I still think it's a sleeper.
