Ricoh GR owners. AF speed, Iso question. And rx100 comparison?
May 30, 2013

I have a question to Ricoh GR owners regarding AF speed and low light performance. In daylight, do you think it is fast enough for grabbing snap shots in the street? How does it perform at, say, iso 1600? And finally...has anyone here had the chance to compare AF speed and IQ to the Sony RX100?

Ricoh GR AF 0,25 sec, Sony RX100 0,3 sec, Fuji X20 0,20 sec. See ephotozine.com.

at iso 1600 it works great. The af is superb in all but the lowest light. It still works pretty good in the lowlight but you want to be careful. I only used an rx100 once but if memory serves the rx100 is snappier however I like using the GRs autofocus controls far more than the rx100 making it smoother to use it in practice

also any ISO and image quality to the RX100 is foolish the GR will monsters it. the GR is more aptly compared in IQ to top of the line apsc dslrs.

It "will monsters it"??  You lost me there.

Hi Kodachrome, have you had the chance to personally compare the two? I would prefer input from real life usage and not "charts" or "specs" comparisons. Thanks.

If you mean it is a monster (magnitude) better, I would beg to differ.

Looking at the sensor sizes first:

1/1.8" 38 mm2 (like org. GR Digital)
Sony 1" 123 mm2 is 3.2x more than 1/1.8"
APS-C 370 mm2 is 3x more than 1"
35mm full frame 860 mm2 is 2.3x more than APS-C

- there is an obvious progression in terms of area here, and it does say something about light gathering quality and noise level, but not all. Still - the RX100 is not bad. Where the GR can do ISO 3200 pretty good, the RX100 does ISO 1600 pretty good. You can compare yourself in the DPR studio-scene page

Lenses also comes into play. The RX100 28-100mm Zeiss 1.8 lens is quite good, but can't compete with a HQ fixed 28 mm like on the GR - at 28mm. Obviously the fixed 28mm will not let you zoom at all.

Autofocus wise I find the RX100 to be surprisingly good, maybe even better than the GR in some situations. I have only spent some minutes with the GR, but it was good too.

You can compare a GR to a high-end APS-C SLR with a HQ 28mm fixed lens, and it will fit in your pocket, but IMO you can compare a RX100 to a medium quality APS-C SLR with a kit zoom lens, and that is also quite an achievement, considering that it too will fit your pocket.

Thanks for the info. I was interested in hearing user's real world comparisons. Most of the time the studio tests do not tell the whole story. There are so many things that can affect AF in the real world.

Thanks for the feedback.

I've been using my x100 lately for casual street shooting (i.e. whenever i go out of my house i take the camera with me), mostly taking quick snapshots, from the hip pictures - you get the idea. I'm mostly using the 28mm-equivalent focal length for that. So, given the similar form factor, i'm pondering the idea of selling the RX100 and getting a GR. I would have a qualitative jump in IQ because of bigger sensor size, but i'm not so sure about operational speed, particularly AF, which the RX100 is really fast for a contrast detection compact.

I was showing off GR to a buddy who had RX100 in hand at the moment. I held his RX100 but handed it over to him immediately. GR has a far better grip. With a better sensor and a good grip and the snap focus feature, a skilled GR user will have little or no issue in capturing pretty decent low lighting photos.

AF is quick and accurate when there is enough light; otherwise, it hunts and accuracy falters...but IMO not as bad as the EPM2 that I had for a short while.

As for noise...well...you can see color noise (not to be confused with luminance noise) with ISO as low as ISO 400 when developed with Photo Ninja...Aperture/LR does not show you that these noise exist...so it's probably a non-issue.

lens is really sharp.  hard to fault it even at f2.8...it's so sharp it even causes aliasing, which shows you that it can outresolve the sensor easily.

You can see the set here.  I'll be adding more to the set as I progress through my written review.

Exactly, that is what i'm thinking. Looks like a great street cam, particularly if you are used to photographing close to the action. I find the 28mm focal length very well suited for working at close distances.

I owned the RX100 before I sold it to upgrade to the GR. In daylight, the AF seemed to be about the same between the two cameras, but in low-light, the RX100 AF was noticeably faster than the GR's AF. If you're willing  to spend some time becoming familiar with the GR's snap-focus feature, then you'll never have to worry about focusing in low light

The GR's snap focus is a zone-focusing implementation, where you prefocus the camera for one of a number of specific (preset) distances, and if the subject is close to the prefocused distance it will be in focus, depending on your chosen aperture's DOF. Obviously, smaller apertures will give greater DOF, so more objects will be in focus. If you're not familiar with zone focusing, it may take some adjustment to get used to this feature, but once you're comfortable with it, you'll find it works very well, especially for street photography.

Even though the GR's AF is plenty fast enough for daylight photography, lately, I'm finding myself using snap focus most of the time for street photography.

The RX100 is smaller than the GR, so it was more pocketable for me. I do sometimes carry the GR in a coat pocket, but it's uncomfortably snug in my jeans pockets.

However, there's no comparison between the GR and RX100, when it comes to the experience of shooting photos: the RX100 was slippery and awkward in my hand, even after adding the Franiec custom grip, but the GR was designed to fit comfortably in your hand, and it's possible to make adjustments to any or all of the GR's settings (and shoot) one-handed. The GR is the most comfortable-to-use, enjoyable camera I've ever experienced, by a long shot.

Also, the IQ of the GR is definitely superior to the RX100. You can see this for yourself by going to the DPR review of the GR and use the IQ comparison widget to pixel peep DPR's studio images for both cameras.

Here's a link to my Flickr GR set, which includes a few photos shot in low-light:
