Canon G1 X preview updated, ISO samples added, gallery to come

By dpreview staff on Jan 13, 2012 at 14:30 GMT

We've spent a bit more time with the Canon PowerShot G1 X, and will be publishing a samples gallery from a pre-production camera in the near future. In the meantime, we've taken the chance to expand our preview based on our further experience and some real-world shooting with the camera. This includes observations about its behavior and a chart showing the camera's maximum aperture at key focal lengths. If you have any burning questions about the camera's behavior, write a comment and we'll do our best to answer when we publish our samples gallery (but do please read the updated preview first, to see if the answer's there).

Canon PowerShot G1 X sample images (pre-production camera) - posted Jan 13 2012

5DMkII... depending on lens used...
offers the following:

EF12 II Extension Tube can be used for magnified shots:

EF24mm f/1.4L II USM vs Above Extension Tube (Optional):
Distance Magnification
Near: 156 mm (6.2 in) 0.67x (Magnified FOV = 36 x 54 mm)
Far: 167 mm (6.6 in) 0.50x (Magnified FOV = 48 x 72 mm)
NoExt: 250 mm (9.84 in) 0.17x (Magnified FOV = 139 x 208 mm)

TS-E24mm f/3.5L II vs Above Extension Tube (Optional):
Distance Magnification
Near: 182 mm (7.2 in) 0.85x (Magnified FOV = 28 x 42 mm)
Far: 198 mm (7.8 in) 0.51x (Magnified FOV = 47 x 71 mm)
NoExt: 210 mm (8.28 in) 0.34x (Magnified FOV = 72 x 107 mm)

All minimum distances for 5DMkII's FF sensor range from 15.6cm - 18.2cm at best, and no where near 1.0cm of a G11/G12. Thus, if one has a significant jump in sensor size such as what the G1 X has, being 20.0cm, this is not unusual.

Agree, they don't tell us yet.

So, my guess for FOV = 25.5mm x 19mm (at 20cm in macro mode)

We'll see.

Can you give any impression on Auto Focus speed? AF speed in lower light? Any better/different than G12, or other mirrorless options?

By Jan_Shim (Jan 13, 2012)

Yes I do have a burning question and it's none other than the minimum focusing distance ... (cross posted as follows from comments left at Preview page)

I shoot with two 5D Mark IIs professionally and for everything else I use the G11. Essentially two very important considerations: the flip out LCD and the 1 cm macro capability (excellent feature for food photography). The G1X with all the other great features has compromised this with a focusing distance of 20cm (according to Dpreview Specs). The G1X quickly went from "high exciting" to a big let down for me.

Question: Does the bigger sensor result in a magnification at such that at 20cm, it's (by any chance?) equivalent to 1cm on the G11/12?

The answer to this is in the updated preview - the G1 X comes nowhere close to the G12's macro capability.

Very disappointing that manual exposure mode continues to mean manual flash adjustments as well.

Hopefully, your sample images can include one photo using the Canon 250D close-up lens.

Thank you DP Review for doing your best to keep us informed. I for one really appreciate the samples, like what I see and understand the difficulty in obtaining realword samples and information in a PRE-PRODUCTION model. I've been looking to step up with my portable back-up camera and this one looks very good. Beat out the S100? Don't know, but the size is definately going to come into play. Better than Sony NEX 7? Panasonic GX1? Lot's to look at with the size factor for sure.
Wouldn't everyone love it if you could go to a wedding, a birthday party, or some such familiar venue with these camera's to get real world low light samples of people? Of course we would, is it feasible, probably not. Really looking forward to the full scale review with samples.
Thanks again for a job well done!

Please test if there is any clicking or other noise from the zoom or autofocus in a recorded video!

When recording for example a conversation indoors with no other backgroud noise and zooming and making the autofocus refocus. I would really like a sample video! I have heard af-clicking and zoom-noise noise in videos from several other cameras...
