Thats actually a UV filter not an ND filter, very different filters :) Anyway, lower quality filters flare more, if you want to continue to use a UV filter consider a multi-coated filter. It seems other people who bought that same filter had similar complaints, see the 1st review: "However, I had to return this item since they DON'T contain any ...

The scene you were shooting (bright spot light + darkness) is actually one that's most prone to flares. This happens will all filters, but some have less flare because they have better coating. Lens construction and coating of its elements also matters. A simple comparison: no filter better filter (Marumi DHG Lens Protect) worse filter (Hama UV 0-HAZE ...

There is an excellent article entitled "How to Photograph the northern lights" that basically states with a point and shoot, it's very difficult to get good pictures. It looks like your camera is one of the higher-end, it should be alright, they have some specific recommendations that I've copied below. It also gives a list of cameras that might do the ...

Actually it is slightly more misleading. 480,000 pixels normally equals 1,440,000 dots but they do get away with only 480,000 actual dots (not pixels) by using something called field-sequential display which is basically 480,000 dots which change colors very fast, sending information for each primary color sequentially. There are only 480,000 dots but since ...

Firstly there are a couple of general reasons raw and JPEG images differ in size, and raw differs from the actual number of pixels on the sensor: Whilst JPEG image dimensions don't have to be multiples of 16 (or 8 if not using chroma subsampling) it is more efficient to do so, as it allows you to rotate the images without re-encoding (lossless rotation). So ...

I will present the "quick and dirty" version of my answer, because I could talk on this topic for pages and pages. Essentially the 14mm f/2.5 "pancake" is a prime lens, which means it does not zoom, it has one fixed focal length. So instead of zooming in and out to frame your subject, you have to move your feet along with the camera! The fixed focal length ...

Actually, shooting with a compact camera rather than an SLR is part of the problem. Basically, shooting a game at night means that you don't have enough light for decent exposure times. As a consequence, your exposures are long and the moving objects are blurred. The field's lighting are rarely enough to allow you to capture moving subjects with ISO low ...

Your slave flash is not fully recharging before firing at the appropriate time and you're seeing the ambient light. Here's how it works; when your slave is set to a lower output it's actually firing twice because it's 'seeing' the 'pre-flash' from your camera and firing on the 'pre-flash' and the actual flash from your camera. When you crank up the juice ...

You guys are on the right track. Here's what's happening in each picture: Slave flash off. Your camera fires a pre-flash The camera determines how much flash power it needs for proper exposure based on how bright the return flash is. The shutter opens, and the camera fires its flash at the power level it just determined. You get a medium-bright ...

Other answers cover everything, but to be blunt: it's marketing bullshit. They are counting each of the three color components of the pixels (red, green, blue) as a "dot". People have been making color displays for decades and only recently has this ridiculousness arisen (for displays, you hear these "dots" called subpixels). On the other hand, for sensors, ...

I'm a bit skeptical about what they are stating. It says that the viewfinder is "1,440,000 dots equiv". The "equiv" term is an annoying marketing term used when trying to be competitive without stating the true nature of something, they are simply stating it is "equivalent to" such a thing. The Electronic Viewfinder is "equivalent" to a "1,440,000 dot" ...

I have a G3, and have really enjoyed using my 3 Pentax K mount lenses with it. Apart from the physical adapter, you will also need to tell the camera to "Shoot without lens" in the REC menu. Apart from the cost savings, you will also get benefits from those old lenses. They are mechanically much more solid, and also (at least for primes) even if you give you ...

So, you're right: you're foiled because the Lumix FZ18 isn't an interchangeable lens camera. The adapter you link for is for Panasonic's Micro-Four thirds cameras, like the Lumix GF1, which do use interchangeable lenses. It kind of confusing for Panasonic to use the same branding for both those cameras and their attached-lens models, but there it is. The ...

You may have difficulty freezing the action and isolating the subject, but that doesn't mean you can't get some interesting shots: with a little planning and a little luck, you could use the longer shutter speeds to your advantage and get some great panning shots. Also, keep in mind that action blur is due to the subject's change in position, relative to ...

From my experience with point-n-shoot cameras shooting sunsets/sunrises I would say the problem is in overexposure. When you try to catch more of what's in front of you the automatic exposure measuring happens on this dark foreground and leads to too bright sky and that really eats out the colors. There is two easy ways to counteract for this. ...

iResolution is just an edge enhancement filter. The "i" part in the name implies, like Panasonic's other "i" features, that the camera automatically controls when, and how much, it should apply this feature. What you select is just the maximum amount by which it will do that - it doesn't mean the camera will use it for every shot. Instead it will ...

To reproduce colour, each pixel needs three dots - one for the red component, one for the green component, and one for the blue component. 480,000 pixels x 3 components gives 1,440,000 dots. When comparing, make sure you compare figures in the same unit (or even consider cameras with an optical viewfinder, rather than an electronic one)

I emailed Bristol Cameras asking the same question since they sell a non-brand battery: Your question was: I thought that Panasonic "secured" their cameras so that only panasonic batteries work. For example, the TZ7 would only recognise it if the firmware was downgraded to pre-v1.2. Can you confirm that this battery actually works in the new ...

I think it's worth mentioning that as much as specifying the dot for each color separately seems like "cheating", this is also exactly how the ratings for sensors have been done since day one in digital cameras. Just for example, a 12 megapixel camera does not have 12 million sites that each sense red, green and blue. Rather, it has (roughly) six million ...

Try taking the photos when the subjects are under a lamp, so there's more light to capture. You might be able to salvage some shots using high ISO and black-and-white. Another option is to shoot video instead of photography - smaller resolution and moving picture are much more forgiving to noise.

I can't help as far as dismantling the camera. However I'd venture that most of us who followed the standard procedure to locate dust on a sensor would have results the same or worse than yours. The procedure of taking a shot against a white wall/screen and using autolevels exaggerates the spots (which is the point of the procedure, to help locate them). ...

This one does NOT fall into the DYI category. Send it to Panasonic or shop for a new one!

Assuming Panasonic hasn't done anything proprietary with the thread pitch on the filters, you should be able to use holders like the Cokin system using a 52mm holder ring. Usually, most of the issues with filter holders and such vignetting is with wide angle shots, but I suspect that the adapter tube is going to be more of an impact than the filter holder. ...

By turning the thumb wheel to the left you will get the pic in pic feature back. Turning it to the right will magnify it again in full frame.

You have to look for the ΓΈ symbol in the objective or the number behind the frontal cup of your camera. However the simplest thing to do is to use a ruler and measure from the inner edge of your camera. Take the maximum diameter you'll find and than search for the filter that most fit the measure. If you post a photo with a ruler near the objective I can ...

I have own this camera for 2 years and I don't have battery problem you mentioned. The camera preserve its battery power well even I forgot to switch it off, the camera goes into sleep mode after a while. Although Panasonic has released a newer firmware but the firmware update isn't relate to battery power. So I guess your unit should have some problem and ...

You can mount pretty much anything on a m43 system using the right mechanical adapters, but that doesn't mean ergonomics are going to make it a practical option, specially on a camera with limited controls like the GF3. You view through the viewfinder as with any m43 lens, but will be working in aperture priority mode. You can trigger manual focus assist, ...

Are there any problems with attaching non-MFT lenses? No, though you will not have access to any electronic/auto features of the lens such as AF, stabilization etc, you'll have to do everything manually. You need to take into account the crop factor, lenses for smaller systems like 8mm, CCTV etc may vignette or produce a circular image with black borders ...

Remember that when using non-MFT lenses on a GF3 (I use old Pentax-K ones) you lose stabilisation, and both the f-stop (older lenses with aperture ring are best) and focus need to be set manually on the lens. As mentioned, "Shoot without lens" needs to set, and Aperture priority (or Manual) mode. Mine works well with a sharp 50mm f:1.4 and a FOTGA PK-M4/3 ...

I have a GF3 with a micro 4/3 -> Pen-F adapter and a 1:1.2 44mm Olympus H Zuiko Lens I took off an old Olympus Pen-F camera. Works great in manual mode for photos. For video I have been unable to activate deshake so handheld videos are unusable. Which is really annoying as deshake is active for the preview when I'm not filming...
