G3 X First Impressions
The G3 X has indeed had mixed reviews. The most positive has, as discussed here, come from the Luminous Landscape’s Michael Reichmann https://luminous-landscape.com/canon-g3x-review/, who claimed it outperformed the Sony A7II and Tamron 150-600mm and is a truly remarkable camera. Others reviewers have made scathing comments about the lack of an electronic viewfinder and the difficulty of handholding at 600mm, and the rivals that have shorter focal lengths are better value for money.
Some of those reviews are clearly silly, not appreciating the importance of a long zoom for some of us and overstating the “lack”of an evf. Other manufacturers have given up evfs, for example Sony on new models and Nikon on their 1” sensor Nikon 1 range, both J and V, where they provide an optional evf for the V3 but not the J series. Canon does have the option of adding an evf, albeit rather expensive.
I need a lightweight travel camera with long zoom to replace my old SX50, which can give good results but has a long shutter lag and lots of light. So, I ordered a G3 X plus electronic viewfinder from Digitalrev on Friday. It arrived yesterday, all taxes prepaid in Hong Kong, at 75% of the UK price – if you can get it here.
The initial impressions are that Michael Reichmann is absolutely right. The camera is very well built and designed, a class piece of kit. The first test shots of my usual street targets show that at iso 400 and 600mm the G3 X out-resolves the Sigma 150-600mm C at f/6.3 on the 5DIII at iso 640, and is comparable to and if not better than the Sigma at f/8. (Processing RAW in DPP – the in-camera jpegs are ok but I don’t like it.)
The focusing is very responsive and reproducible – using just the small centre frame so far. The shutter lag is indeed very short (stated to be 0.044 s). I found it easy to handle at 600mm with the evf. The noise is far better than that from the SX50, but I need DxO to upgrade so the G3 can be processed on DxO Prime, which I need to do with lenses on the 7DII at iso 640 for heavy cropping.
OK, it’s not the 100-400mm II on the 7DII in terms of being able to do birds in flight easily and do pinpoint focusing of a small bird half hidden in foliage, and won’t do high speed continuous with its low frame rate. But, it will be taken on every trip I do when I can’t take my 100-400, and it will be a lightweight for my wife to carry on longer hikes. And in half-decent light for bird portraits it will give comparable quality – but take a pocketful of spare batteries.
