In a previous post I demonstrated how the Canon’s 18MP sensor produced identical resolution to the Pentax K100D’s 6MP sensor when shrunk down to “Internet size”. That is a difference of 3X the pixels producing the same quality image in the end. Really the only advantage to higher resolution is the ability to crop further: ‘post-shooting digital zooming’. With the acquisition of the Sony a6000 it was only fair to see how 1/3 more pixels held up to this axiom.
There are a few other considerations in my comparing the cameras as well, mostly in respect to my personal usage of them. The Sony can adapt almost any old lens by virtue of being mirrorless which gives a great deal more space between the sensor and the lens to accommodate adaptors. Case in point: in order for a Canon FD lens to work on the Canon T100 you need a fairly expensive adaptor with a ‘refocusing’ lens in it, whereas with the Sony it’s just a big metal ring. $40 vs. $20, and that extra piece of added glass will have some effect on the resolution.
Two other operational differences are that the Sony is physically smaller and has an electronic viewfinder. Otherwise they are both APS-C ‘crop sensor’ cameras, albeit with a tiny difference in the crop factor: 1.6 for the Canon, 1.5 for the Sony. Hardly significant, yet it does show up in the pictures.
Dealing with dodgy weather, I first did some pictures using each camera’s standard kit lens: Canon 18-55mm and Sony 16-50mm. Fairly similar, but the Canon is slightly more telephoto at both the wide and narrow ends.
Another similarity between the two lenses is that neither will win any awards for sharpness. They’re “good enough” for average shots, but not up to my standards. I can see this even with my failed eyesight, so it must be painfully evident to anyone with sharp vision.
For the record, both cameras were set to “automatic everything” and “standard” colour to see if they would handle the same scenes differently. On the whole there was only a slight tendency towards less exposure for the Canon. Enough so that it made me go back and check to see if I had set compensation at -1/3 or something. I hadn’t. Colour on both cameras is fine ‘right out of the box’ and I couldn’t see any significant difference in the end results. (I did shoot more pictures than are presented here; these are selected for example purposes.)
Of course to pit camera against camera you have to use the same lens on both, so out came the 50mm f1.4 Super Takumar:
If it weren’t for the obvious clues in labels and field of view you could not tell which was which. Obviously the cameras are comparable quality.
(Note: at retail the Canon cost half what the Sony did, and I wouldn’t have bought the latter had it not been offered at a significant price reduction.)
Now from my personal experience the Sony has four shortcomings:
1). It is smaller, which makes it harder for me to handle. This can possibly be overcome with the addition of an accessory hand grip, but that would be even more money spent.
2). It is mirrorless, and there’s already spots on the sensor again after being cleaned the first time. A bit of a drawback for a camera you would like to change lenses on fairly often in order to use vintage glass.
3). The EVF is noticeably dimmer than the optical finder of the Canon. It has settings for brightness, but this revelation is very significant for me personally.
4). Although the exposure metering in Manual is superior in operational ease to the Canon, the focus is terrible because wide open results in the EVF being a glare of overexposure and you can’t see to focus anything. It is necessary to either switch modes for focusing and then back for exposure or ‘guess focus’ or ‘pre-focus’ – all of which is a pain to do. The Canon does not have this focusing issue due to the optical finder, but checking exposure requires looking at the back screen. (Note that the display symbols in the Sony’s finder are difficult for me to see, but I can manage them and others would have no trouble I suspect.)
What else? Well there is something of a paradox in using the camera with the best, fastest autofocus I have ever seen (better than the Canon or any other camera I have) with manual focus lenses, but there we are. As for obtaining further Sony or third party automatic lenses … egad, the prices! A cheap tele zoom is almost as much as the whole camera cost, and quality primes or long focal length zooms (I tend to shoot telephoto mostly) are twice what I paid for the thing. To be fair, other manufacturers’ glass isn’t much cheaper. Cheap lens tends to equal low quality imaging, hence my fondness for the antique Super Takumars (which are now also insanely priced on the used market when you can find one).
Where do I go from here? To be honest, around in circles. I have debated buying the hand grip ($70) or an FD adapter ($20 – I have one FD lens and it’s not a Canon) or the ‘inexpensive’ tele zoom ($300+) or selling the camera on, and can’t see any way clear.
What I have discovered is my eyesight is terrible and the EVF cameras I have are all now difficult to use because of that. This puts me up against the wall for many things, not the least of which is using my favourite (and ailing) Nikon P610 superzoom for birding. You can not get an optical finder camera with a 65X zoom factor. Not that it would be impossible to make one (imagine a DSLR with a 1/2.3 sensor), they just don’t. The Olympus E410 has a 2X crop factor, but again the lenses available are few and expensive and don’t begin to reach into the Nikon’s 1440mm equivalent range. This is physics spoiling my fun again.
Right now I’m trying to feel proud of myself for not buying a lot of lenses and whatever locally for cheap, and mainly I didn’t do it because the seller couldn’t be bothered to make an itemized list even when I asked for some specifics. Well then I can’t be bothered to drive for over an hour to look and see if any of it is something I can use.
It’s typical that since I have recovered from the operation that the weather has turned bad thwarting any adventures in photography for me. I’m bored, and that’s a dangerous thing.
Oh well at least I don’t live in any of the disaster-struck areas of BC. The effect will no doubt be higher prices on everything, as that’s always what happens, but I haven’t actually lost anything due to the flooding – unlike so many others.
