Have you seen a gallery showing decades old photographs from 35mm film? All mirrorless cameras do better, much better. Do you think those pictures would get rejected today on the grounds of being to grainy, unsharp or lacking contrast? Gallery quality has much more to do with with content of photographs than anything else. Light, color, gesture says Jay ...

It's called "Nisen Bokeh" and is mainly due to the lens design (though the background plays a part, it's possible to "provoke" this effect with any lens with the right background). Overcorrected spherical aberration (blur disks which are brighter in the periphery than the centre) is usually to blame. It's showing up more often with the A7 due to the use of ...

I think it's more the latter of your two reasons: the experience, talent, and care of the group who are willing to spend more on higher-end gear, vs. the format size alone, that creates the impression that better cameras make better pictures all by themselves. Someone who's willing to spend $2000 on a camera body and another $3000 on glass in a brand new ...

Distortion caused by a lens's optics would give you barrel distortion (objects appear to bulge outward) or pincushion distortion (squishing inward). The skewed lines you are observing are straight; this is perspective distortion, and is not a problem caused by the lens nor fixable with better optics (you can fix it with a tilt-shift lens, but that's a ...

One good solution is to get a Hot Shoe Flash Adapter so you can use your old external flash right on the camera, or get a smaller Manual only flash to trigger your external optical slave flash. $10 Amazon Hot Shoe Flash Adapter MSA-10 for Sony NEX 3 An even better solution is to get this Wireless radio transmitter/receiver: $10 Wireless Flash ...

You're not buying the camera for the lens, nor planning to use only that lens, are you? And the review is not that bad: the lens is actually pretty good in the medium to upper range. Mainly there seems to be two criticisms: at the wide end, resolution is not good - but still better than not having it at all; other kit zooms just don't go that wide. ...

In terms of which angles of view the lens(es) will allow you to select, you're correct: the combination of an 18-55 lens and a 55-200 lens will let you choose from exactly the same angles of view as a single 18-200 lens. However, I think you are missing a couple of important points, both of which are well covered in this answer: you'll get better image ...

In most cameras the scene modes automatically set the file type to JPEG and apply different processing settings to those files (Landscape mode often boosts greens and blues, sunset mode boosts reds, for example). They also prioritise aperture and/or shutter speed appropriately. However, this comes at the cost of creative freedom - the camera is making all ...

AF-C mode is a continuous focus mode. That is, it will not "lock" focus and hold it until the picture is taken. It is best used for when you are tracking a moving subject such as an athlete moving across a field. It will constantly check the focus as the scene changes and adjust to those changes. The reason you see this behavior even in static scenes is ...

You're getting what is called Perspective distortion which is most noticable in wide angle lenses. Check out this link for more info: http://en.wikipedia.org/wiki/Perspective_distortion_(photography) Basically close up objects in the center of the frame will look enlarged while objects on the sides will be stretched away from the center of the photo.

These are different designs, developed at different times. Forty years have gone between each was initially launched as the A-mount was simply acquired from Minolta which had by then fused into Konica-Minolta. The A-mount introduces AF which worked by Phase-Detection and hence lenses for that mount are designed to focus that way. Over the years, they were ...

No, larger sensor cameras are not more likely to mis-focus - if you take the Canon 1DX (with a modern lens) for example, it's a full-frame camera that's about as far away from "likely to mis-focus" as possible. But when a large sensor camera mis-focuses it's more noticeable, especially when most tiny sensor cameras (cellphones) have wide angle lenses. The ...

The first flash is probably for light metering (Canon call their version e-TTL, Nikon iTTL if you want to read about how it works), but the external flash doesn't know that of course. You should be able to get an external optical trigger that can handle this (a hotshoe with a tripod thread on the bottom). Optical triggers are cheap so this would be a ...

Sticking with your requirements of around 12mm or so focal length, rectilinear, autofocus and less than around $400, the simple answer to this is "no, you can't have that" even if you're prepared to compromise on other things like speed, optical quality and (lack of) zoom. If you're prepared to give up on autofocus (which generally isn't too much of a ...

I have a NEX-5n and as far as I know there is no way to intentionally leave the shutter closed. The way the camera works is that the shutter is always open for live-view, focusing, and metering. When you press the shutter 'release' the shutter closes, opens for the appropriate exposure time, and then closes again while the sensor is read out, and finally ...

Yes a 49mm - 58mm step up ring is what you need. Here is one at BHPhotoVideo for example. And here are a bunch of results at amazon. I would also consider one of the kits that come with multiple step up rings such as this: http://www.amazon.com/Fotodiox-Anodized-49-52mm-52-55mm-55-58mm/dp/B001G445Q4/ref=pd_bxgy_p_text_y

Theoretically both images should be the same brightness, even though the NEX sensor is larger, it stills receives same amount of light per unit area both lenses were set to f/3.5. The difference in brightness is due to different processing, there's nothing in the ISO standard that guarantee the same digital brightness values given the same exposure and ISO ...

It is not. What you are referring to is sensitivity to light. That is the ISO sensitivity is for and while there is a standard that describes it, digital sensors do not match exactly the posted sensitivity. A site like DxOMark actually measures ISO equivalence as part of its sensor benchmarks and you can commonly see a difference of ±1/3 EVs. The other ...

There are many photos in the A6000 pool that look amazing [...] I can't get that close with any of my photos on the a6000. I think this is probably the most important point here - the photographer is much more important than the gear in making a photo. The best thing you can do at this point is to go away and practice, practice, practice (and possibly ...

Most advanced cameras allow you to separate exposure and/or focus lock from a half press of the shutter button to allow each photographer to choose how and when focus and exposure are locked for a given composition. Even what happens by default in the camera's "factory" settings will often vary based on what shooting modes in terms of exposure and focus are ...

Metabones makes an EF-to-E adapter that brings all of the electronic features across except autofocus and some of the lens correction information. A full-featured adapter could happen, but you could lose out on an awful lot of shooting waiting for it. Selecting lenses with an eye toward the future is a good idea, but the adapter's US$400 price tag makes ...

Short: Turn camera OFF when not used. If that makes no difference, remove battery from camera. Just opening the battery door so contact is broken should be enough. (ie camera will not turn on. If using in standby look to see if any optional features make a difference (GPS, Bluetooth, WiFi, ...) If battery discharges completely from full in 3 months when ...

As an owner of an NEX-6 and two of the more expensive lenses currently available for it (the Sony 18-200mm zoom and the Sony Zeiss 24mm F1.8), and with the warning that I may be doing nothing more than reinforcing my own biases, I would say that, if they meet your needs, you shouldn't hesitate to purchase E-mount lenses. Why? First, the mirrorless camera ...

You are correct that there is no free lunch. Software NR works by looking for sharp edges and trying to identify what is detail and what is noise, but at a very fine level, they can't be distinguished. What you will normally see with light NR is a reduction in fine detail, but gross detail is maintained. The more you turn up NR, the more gross the detail ...

You are looking at it wrong. I've never had an accident or ever even seen an accident occur while I've been driving, but Nascar drivers are either in or witness accidents all the time. Does that mean that Nascar drivers are worse drivers? No, it means they are in situations where accidents happen more frequently. The same thing applies to your Flickr ...

I think the key thing for here is that smaller sensors inherently have more depth of field at the same aperture number and framing. That means that with a larger sensor, focus is more critical. It's not that the larger sensor is really worse. With a camera phone, in low light, the result will be very noisy (with automatic, non-optional noise reduction ...

An adapter is great if you already have Canon lenses or want to share lenses between Canon DSLRs and NEX cameras - but it isn't that good compared to getting the Sony lens. No adapter is perfect (actually, the lens and camera aren't perfect either) The adapter will add some more (usually small and almost unnoticeable, unless you pixelpeep) misalignment to ...

The ratio f/2.8 means the diameter of the entrance pupil is equal to the focal length divided by 2.8. The key thing to note about the above is that the entrance pupil is the image of the aperture stop as seen through the front of the lens, the ratio does not depend on the physical size of the aperture itself. A rear-mounted 2x teleconverter, such as you ...

If you're using a disconnected non-dedicated external flash like this, it'll be unmetered - you'll have to set all the exposure and flash parameters manually to get the image you want. The first flash from your onboard flash is a metering flash for auto flash exposures. With manual exposures like this, it's neither needed nor even useful. So, set your ...
