No, this is not chromatic abberation, as others seem to think. Chromatic aberration is a real phenomenon, but not the dominant one here. The background is grossly overexposed. Lenses aren't perfect, and some small fraction of light that is supposed to be focused on a point ends up in other places. Even if the lens by itself were perfect, a little bit of ...

The DxO Mark scores are misleading, but that doesn't mean the gap in performance isn't real! Several Nikon bodies (D800, D600 many of the D3xxx and D5xxx series) are using Sony Exmor sensors which feature a cutting edge ADC/read noise reduction system to achieve massive gains in dynamic range compared to Canon sensors, which are designed and fabricated in ...

In addition to the points Alex S made, you need to consider why they want RAW. There are several possible reasons: Bit depth as Alex S said. JPG suffers from compression artefacts which RAW doesn't. Blown up to exhibtion size these can jump out and ruin a print. Having the RAW file is often used as a proxy for having taken the photo, as RAWs aren't ...

Disclaimer: This answer does not offer any help with decreasing shutter volume - it is an anecdote and therefore just a viewpoint that is related to your status quo. I think that there is not much you can do about it - if you are aware that your camera is non-silent and you try your best to avoid it being disturbing, you already did everything you could. ...

It is not just cheaper lenses. Many modern lenses, especially Auto Focus zoom lenses have this characteristic. There are several reasons for it: Unless a lens is parfocal the exact point of infinity focus shifts as the lens is zoomed in or out, and so obviously there will be a point where infinity for one focal length is past infinity for another. As ...

Because that rainbow is partially obscured by your subject, I would tend to believe that it has nothing to do with any of your equipment. Rather, there was something in the room acting as a prism and diffracting light into a rainbow pattern that just happened to fall within the frame of what you were shooting. It might be that the source of the light was ...

RAW is not (or minimally) processed image data from camera sensor. JPEG is processed image data. Typically, raw-files from modern cameras have 12-14-bit per pixel which means up to 16384 values (for more details see Michael Clark's comment). JPEG can have only 256 luminance values per RGB channel. This means that jpeg contains much less data than a ...

First: please recognize that despite what you may read on click-hungry review sites or fan-fueled forums, every DSLR and mid-to-higher range mirrorless camera on the market will be stellar for the purposes described. Any differences are details — every option is an A and it's then down to arguing over A+ or A++, as well as subjective factors or very ...

I think you are putting too much emphasis on the "digital" part of the lens' DG designation. It seems to be more to differentiate them from "digital" lenses that are APS-C only. Sigma calls their current APS-C only lenses "DC". When digital SLRs first began to gain a foothold in the market, they almost all had sensors that were APS-C or similar sized. So new ...

When using manual focus you have to adjust the plane of focus using the focus ring to acquire correct focus. You will have to choose this yourself and if I understand you correctly you have not done this. Of course there is a slight chance that the lens will already be set to focus at the depth you want but they are slim indeed. Using a wide aperture will ...

The focal length/speed is only one factor in the retail price of the lens. Other goodies like construction (metal vs. plastic), image stabilization (and other automation in general) and vintage can easily add (or remove) a zero. The two lenses in the question are very different products. The 2.8G is a newer product and lacks an aperture ring - the diaphragm ...

Yes, lenses designed for digital sensors have several differences from their older film based camera lens counterparts. One of the primary differences is that digital sensors are more reflective than film, so anti-reflective coatings are applied to the rear element of a digital lens. This helps prevent reflections off the sensor that could result in image ...

You can run the camera directly off AC power with two pieces of gear. You need a camera-specific "dongle" that basically fakes being the battery in the battery compartment. This then connects to the other part you need, which is the AC-to-DC adapter. For the D3100, you need the Nikon EP-5A power supply connector and the Nikon EH-5b AC adapter. According ...

You changed from sRGB to Adobe RGB1998? It's apparently the naming convention. It surprised me too when I did the same thing. From my D5500 manual... Photographs are saved using file names consisting of “DSC_” or, in the case of images that use the Adobe RGB color space (0 243), “_DSC”, followed by a four-digit number and a three- letter extension (...

The problem is your shutter speed is too fast for the type of lighting you have. Most LED lights flicker (and fluorescents, in a slightly different manner and degree) at either 50/60 Hz, or 100/120 Hz, depending on the mains frequency where you live. At a shutter speed of ¹⁄₄₀₀ second, it's a bit of a crapshoot whether your shutter will be timed with the ...

I am using a D5200 and wish to find the height of the centre of the sensor from the base of the body. I don't know the number, but you should be able to measure the distance easily enough. It's a good bet that the sensor is centered within the lens mounting flange, so you really only need to measure from the inside edge of the flange to the bottom of the ...

In order to control the aperture from the D3400 with an older 'D' type lens that has an aperture ring, you need to set the lens' aperture ring to the narrowest (highest f-number) and lock it there. If the aperture ring is in any other position, the camera will not operate the lens' aperture properly. Keep in mind that there are a few other considerations ...

The shutter speed now is 250 From what I can tell from the Google, the Nikon D3100 has a flash sync speed of 1/200. So, you're setting your shutter speed too fast and the curtain is already starting to close when the strobes pop. Your maximum should be 1/200. But, honestly, there's no reason to even flirt with the edge that much. You can go down to 1/125 ...

You certainly knocked the diopter adjustement out of place. It is there to compensate for people who need eye-glasses. With your eye looking through the viewfinder, adjust the knob on the upper right side until you see what is in focus clearly sharp.

So, there a couple of basics to get out of the way first. Pentax DSLRs are just fine compared to Canon and Nikon; they're solidly built, have a decent but smaller following, and in fact often have better features at the same price level (because they need to, to compete). That's not to say blindly that "Pentax Is The Best!"; in fact, they're all great and I ...

They don't test every unit. It isn't necessary. They test some units. Having a shutter count of zero is perfectly normal and not a concern. I have read anecdotal evidence that people who have owned dozens of DSLR cameras have always received cameras that have a shutter count of zero. I believe it to be few and far between that people receive units that have ...

CIPA ratings between two cameras from the same generation and from the same manufacturer can sometimes be useful. Comparing CIPA ratings across different brands is pretty much meaningless. Here's why. CIPA rating - A measurement of the number of images a digital still camera can take on a single battery charge. The procedure for determining this rating ...

Calibrating your Shutter Speed Unless you are performing photographic telemetry or a variety of other niche scientific measurements, the only reason to know the exact length of your exposure is to achieve accurate exposure. Although it is rare for a modern camera's shutter to drift by a stop or more and still continue to function, old war horses with spring ...

You appear to be using your lens (100-400/5-6.3) with the aperture wide open. I would expect the glow in your photos to be significantly reduced or absent stopped down to about F8. Many lenses "glow" when used wide open, especially in bright light with high contrast. It is likely associated with spherical aberration and is typically reduced or completely ...

The short answer is that all else being equal FX will give sharper images, at least in the centre of the frame (possibly not in the extreme corners with wide lenses). The long answer is here. The typical argument that gets rolled out against full frame is that lens sharpness falls off toward the corners, so using the same lens on a crop body avoids the ...

I don't know what specific model rotary wheel Nikon used in that camera, but moving it fast shouldn't cause any excessive wear. These rotary wheels are usually just rather simple mechanical switches. There are usually two separate switches. Each goes thru one complete cycle each detent, but the two are off from each other by 1/4 cycle. The fancy name for ...

Not for this reason, you shouldn't. You say "The pictures come out so bland. But when I use the same settings on my friend's cameras, the pictures are so much better." Some settings, like Aperture, Shutter, and ISO, are camera fundamentals and won't be any different. But things like Color/Saturation/Contrast are in-camera post-processing options which won't ...

It's actually pretty similar except that they changed numbering when they run out of digits in some series. For the current lineup: One-digit DSLRs are top-of-the-line full-frame cameras. The higher the number the newer. So D4 is newer than D3. There are sometimes variants such as D3S which is specialized for low-light and D3X which is specialized for high-...

As noted in Nikon's knowledgebase, the D60 supports SDHC cards, but implicitly not SDXC (as SDXC is never mentioned in the page). This isn't surprising as the D60 was released in January 2008 and the SDXC standard was announced in January 2009. The SDHC standard has a largest possible size of 32 GB, hence your 64 GB card must be an SDXC card and is not ...

The Nikon D5 and its predecessors are mainly intended for action and sports photographers. They are designed for speed and sensitivity in order to freeze fast moving action and capture it at its height. This is the main reason why these models traditionally offer fewer megapixels. This lets the camera shoot faster, have better throughput and fit more images ...
