I got the original nikon d7200 batteries before, but its first initial 1st charge drains very fast. I tried to used them for a couple of weeks so they have definitely run down. And up. They've gone from full to empty very fast. Does anyone have any experience of using third party batteries like LP Neweer Vemico or some other brands?

I need another LP-E5 type battery for my Canon 450D. Should I buy an original Canon battery or one of the many generic brands available? There are loads of cheapos on , for example.  I should add that the new battery will be added to my existing Canon battery in a battery grip.  Does anyone have any experience (good or bad) of using generic batteries?

Recently, Nikon announced their , as revamp of the old 50mm f/1.8D. :     The main difference between this new   "nifty fifty" and the almost   decade-old ƒ1.8D is that it has an   autofocus motor inside. This means you   can use it with any current or recent   Nikon SLR. The older lens lacks this   motor and is instead driven by one in   the camera, which cheaper bodies don't   have.   I currently use a Nikon D80 (and I don't plan on changing that any time soon), and I've been considering getting such a lens. Is there any difference between the D and the G lenses when used on a D80? I believe that the D one works just as well, since D80's have internal autofocus motors - is that right?  Besides the autofocus motor aspect, is there any other big difference between them? Since the D is priced at around $120 and the G at $220, should I just get the D?

Recently (and always at the worst possible time) my camera will either freeze and give me an f/0 error code or will shoot with a strange click that sounds like the shutter is getting stuck. The resulting image is always black.   My gut instinct suspects there is either a communication problem between the lens (Nikkor 24-70 ED) and the camera or the aperture diaphragm is in the process of failing.

Platform: OS X: Yosemite 10.10.4; MacbookPro 15" Retina (mid-2015). Fact: There is aging for battery in any case - using or not. But while using - there is difference of how to use. My questions - in order to minimize battery degradation:    How often should I totally discharge battery ? Is degradation rate is a matter of full cycles or it doesn't matter to what highest and lowest level I charge or discharge laptop ? Most (99%) of the time I am connected to power - which leads to 100% charge level always. But many sites say, like following link:  say, that better to keep battery 40% charged than 100%. How to achieve that (there is no ability, as far as I know, to manually limit charging battery level) ? Do you have empirical evidences to prove or disapprove this expectations ? I ask this since to replace battery in Macbook Pro is hard to be done - many screw types, many modules do disassembly, using glue to grasp components without moving inside. And therefore I prefer doing this rarest I can. How much time (how many years) it typically takes upon your experience to get to buttery degradation of 40% capacity compared to Day-1 of using your Macbook Pro ? After 2 minutes of laptop using - the internal temperature (CPU, RAM, Battery) gets to 85-90 degrees (Celsius) and stays so till I turn off (sleep) laptop - for 12 working hours every day. Is there something I can do about heat (both in general, and regarding battery especially)?   What else should I do or know to not be frustrated later ?

I had an unfortunate accident where my DSLR camera (and me) briefly ended up in a river. The camera wasn't fully submerged but it did get very wet. It still works, sort of, although the electrics are doing some random things. I'm hoping that's just a bit of dampness doing that, that will fix itself when it dries out fully.  More concerning is that the documents exposure metering seems to be all wrong when using the viewfinder. Pictures are extremely overexposed and nearly white. But if I use live view, then they are fine.  Why could cause this? I assume the light is routed a different way when using the viewfinder and maybe it is going through something with water/condensation on it?

I've got a couple of spots of dust on the sensor of my Canon 20D. A rocket blower isn't shifting them, and I'm ridiculously scared of some of the more direct methods for cleaning sensors — what methods/systems have you tried, and how successful have they been?

Two years ago I bought my first DSLR. Since then I have bought and inherited some lenses. What should I buy next, a better body or more lenses? I enjoy photography but I do it fewer than I'd like (not enough time). I am not planning on selling photos nor services, just doin' it for fun.  This is all my equipment:   Nikon D60 Kit lens 18-55mm f/3.5-5.6 VR      Filters: Circular Polarizer and ND-400 Very crappy tripod, before any body or lens I will buy a better tripod.   As you may have noticed I've inherited some pretty old lenses from my father (also a great old film camera, but I don't use it). I use them on full manual mode as  implies on a similar case.  So my question is, should I invest in a new body or still add some more lenses? Which body? Does it make sense for me to go for a full-frame body (I guess that no)? Which lenses would you recommend to add to my equipment? and the more important question: Should I buy first a new body or a new lens?

I'm looking for a new compact camera that:   has a  is small enough to be mountable on a  and, runs on AA batteries. good flexibility   Requirement (3) stems from the fact that I may be hiking in the wild for weeks on an end, with no opportunity to change a Lithium-Ion battery. If another solution permits me to take thousands rather than hundreds photographs on full charge, I may consider that as well.  Additionally, it would be nice (but not essential) to have:   the ability to handle high dynamic range a viewfinder physical buttons — I live in a cold climate, and don't like to use touch-screens   The upper price range for compact models is still good for me, and I don't mind a pricerange of €400–€800 (but I don't mind cheaper either, if still of good quality).  I've been the happy user of several models in the , but now my PowerShot A650 IS has died. Starting from , it seems requirement (3) kills of many cameras: the , (might also fail (2)), the , the , the ... Although enough models meet requirements (1), (2), and (4), as well as the (non-essential) additional features I listed, it seems in the past 5 years, cameras have moved away from using AA batteries. What camera models still exist that meet my requirements?

This is my first question in /photography. I'm a very amateur photographer, doing things wrong and by eye with lots of trial-and-error all the time.  I currently own a reflex Nikon D70 my uncle gave us after he bought a better one. It has some nice settings, and he bought a a Nikkor 28-80mm F/3.5-5.6 zoom lens for it. It behaves nicely, but it's getting old (it has those old cartridges before SD cards existed) and every new charge takes longer than the last.  I'm planning to upgrade to a better camera, and there are some neat offers on a nearby superstore (MediaMarkt), this one catching my eye:  Sony DSC-H400 63x, Sensor Super HAD 1/2/3 CCD 20.1MP -> for less than 300€ taxes included  I don't have any type of extra information aside from that, all I can get from the official site is clinical data from other cameras that I suspect it's not 100% accurate, and there's no photography expert on the store to ask.  The common things I use my D70 for are: taking pictures of scenery (castles, towns, forests, waves hitting rocks, etc...), nearby (&lt;5m) persons and objects, and well, things where I want to save a memory in digital format, not for professional purposes at all.  Being that my objective is to have a decent, good-zooming (superzoom looks awesome), amateur (but with manual settings) camera, is this Sony a good replacement? Will I miss any features? Is there any better, similarly-priced alternative you know of?  Basically, I want to know whether I will get better quality photos than I currently do, given the examples, with any averagely-priced bridge camera similar to that Sony, and if it's worth it.  examples of current camera results  Full zoom-out of town at night, bad quality I know; notice the pink blur at the left.    Maximum zoom on that pink blur from almost the same spot:    Daylight, cloudy, modified with Adobe Lightroom, scenery:    Same day, same beach, different settings:    Same day, same beach, rocks:

I came across this  on Stuck in Customs today that makes a strong case to hold off too much investment in DSLR gear, and instead switch to mirror-less cameras like the Sony NEX. The author prefers to call such cameras 3rd generation cameras to prevent any bias.  The crux of the argument lies in the smaller size and faster shooting speeds of the new cameras, while the sensor size is an area where they seem to be lacking (Sony &amp; Samsung cameras are APS-C sized though). Currently the big makers - Nikon &amp; Canon - have practically no presence in this market (Nikon seems to be doing something with the V1). However, they seem to have slowed down the introduction of new entry level DSLR models over the last year as well.  So, as DSLR users looking to build and enhance their kit (there are many like me who've jumped the bandwagon over the last couple of years, and are just starting to build their kit), what are the advantages of sticking with the DSLR system rather than switching to the 3rd gen cameras?  IMO, one point that could cause a massive switch in the DSLR base would be if Nikon &amp; Canon announced mirror-less models compatible with their current lens lineups, but that is a hypothetical scenario.  P.S. There is a similar question on mirror-less cameras, but that seems to be from the perspective of a person starting out rather than a person already invested in the DSLR system.

I have an old Minolta Maxxum 7000i AF-SLR camera from early 90s. I have a complete set of lenses, filters, etc., I found out that Sony ultimately ended up buying Minolta, and developing their alpha cameras from Minolta cameras.     I know it is a fat chance, but was hoping to find out if anyone has tried using the Maxxum lenses on the new Sony Alpha series?

Being a beginner, I can't see why I must choose an 80-200 over an 18-200. Are there scenarios where an 80-200 would be preferable over an 18-200?  I will be buying a D7000 soon and am looking at these:       but similar considerations would apply to other brands as well.

I am new to photography and I was hoping to go take some pictures of star trails this weekend. I just bought this camera this week and I realized that the highest shutter speed is 15 seconds. Is there any way to keep it open longer? I don't think this camera supports bulb mode.

Hello recently I went to best buy and played with a Nikon B500, it was great. I was able to focus on the smallest things, close or far, zoomed all the way in and all the way out. So I went on the internet and found out that the B700 shoots in raw so I got it instead thinking it was better. Only I cant get it to focus on anything close up, weather in macro or not after like 25% zoom it no longer focuses on anything no matter what settings I put it on leaving me to think that I should have gotten the cheaper B500. It may not shoot in raw but at least it would be usable. I am fairly new to photography I had a friend with much more experience come over and try to figure it out. He told me that my camera has a range that it is able to focus on. Only the cheaper B500 focused on things way more zoomed in and with the camera much closer to the object so it doesn't make much since to me. So my question is why wont my camera focus on macro shots (weather in macro or not)?

I have had my Nikon D40 for a while, and some of the pictures are coming out distorted. Two examples are below:   So my questions are:    How do I fix them after the fact? - i.e. after they have been imported from the camera - if possible How do I prevent future pictures from being distorted like this?   Thanks   and

What is the current state of things when it comes to super capacitors and batteries? Are super caps anywhere near rivalling LiPo's in capacity?  I've often heard people talking about super caps as being a viable replacement for batteries, in that you can charge virtually instantly and recharge millions of times, but is this just a pipe dream?

I'm looking to buy a new camera. I've looked at  and decided that mirrorless is right for me. But what next?   What should I be looking for when shopping for a mirrorless interchangeable lens camera (and what should I not be concerned with)?
