No, see, it's not locking down their system, it's their patented Photon Integrity Security System, which Canon has always been known for, if just by the acronym.

Huxley posted:Is there a reason to buy anything other than the $50 Chinese extension tube sets on ebay? If you want AF the kenko sets are probably your bestbet, although there are some other brands of af tubes on amazon for around 50 bucks . If you don't need AF or auto aperture you can get dumb tubes for under 15 bucks on amazon most likely.

When you guys use Variable nd filters, what kind of hoods are you using? Are my only options the screw in type ones? (Mainly because I use a 77mm nd and the front screw in is 82mm-eBay gives limited options for non metal hoods such as the petal shape only.)

Wondering if anyone else has had this problem with Nikon digitals, I mounted a older AI lens on my d7000 today and the body seems to think the minimum aperture is now f48 and max is f8, lens is max of f3.5, pictures look exposed fine though. I has issues with a sigma lens from KEH doing a very similar thing although that was an AF lens with a aperture ring. Is it possible the sigma lens busted something?

Did you enter the lens specifications properly when you put it on the body? The D7000 has no way of knowing what a non-CPU lens is unless you tell it focal length and max/min apertures. On the MENU screen, there's a section for "Non-CPU Lens Data" in which you can assign the lens a number and enter its specs.

Yeah, the AI sensing tab tells the camera "the aperture setting has changed by one stop", not "the aperture is now f/4". If the lens doesn't have pins on it, the only way the camera is going to know the maximum aperture of the lens is if you tell it, so even if it's exposing correctly, you're going to be seeing a bunch of nonsense in the viewfinder if you didn't set it right.

I'm looking to purchase an all around decent camera. I don't know anything about photography but I'm wanting to learn. I'd like to have something good for photo and video. I have spent weeks reading and am currently thinking about picking up the Panasonic FZ200. I can't decide if I should take the plunge on it or get a budget DSLR. I'm just not sure if I'm ready to worry about lenses. Some of the sub compact cameras were pretty interesting too. I have owned a Canon G9 but I never did much with it. I'd like to keep my total budget at around $500-800. I don't have any specific needs and I know there's no camera that does it all. I'd just like to come as to an all arounder as I can. I really like the zoom capabilities of the FZ200. Thoughts? Is there a better investment? I haven't totally ruled out a lensed based system.

Ezekiel_980 posted:Ah that explains everything and now all the numbers make sense! I figured that all Nikon did was retrofit a system from the old cameras that made it into info the camera can read. From Wikipedia: "Manual focus with "Automatic Maximum-Aperture Indexing," introduced in 1977. The AI standard adds a Meter Coupling Ridge to the aperture ring, which encodes the current aperture setting relative to the maximum, and a Lens Speed Indexing Post on the mounting flange, which encodes the maximum aperture itself. The Ridge and Post couple to the camera's light meter. Lenses designated AI-S, Series E, and AF all include these features of AI. Current professional Nikon camera bodies link with the Meter Coupling Ridge, but the Lens Speed Indexing Post is ignored and the maximum aperture value is set electronically by the operator instead. AI-designated lenses also improved on the original Meter Coupling Prong, adding cutaways which allow more ambient light to fall on the aperture ring, increasing visibility on cameras which optically projected the setting inside the viewfinder." Neat.

grack posted:Make a list of what you want the camera to do, and then put them in descending order with the most important at the top. This is difficult for me since I don't know really what I want to do. What I want is pretty generic. I'm mostly just wanting something to learn on and explore with. So..without really knowing what I'm talking about... 1. Picture Quality/Speed 2. Video Quality/Recording length 3. Low Light Capabilities 4. Decent Zoom Capabilities 5. I don't want to mess with post processing at first. So an assortment of features on the camera would be nice. 6. Something with the fundamentals to learn on. But not something that's overwhelming. 7. I like the idea of physically having full manual control with actual tactile buttons/knobs to control said features. As in, I don't want to be stuck doing everything through menus. I want to feel what I'm doing. And be able to make changes to zoom, focus, aperture, shutter speed, ISO. 8. Something I can grow with. Or add on to if needed. Something I'd still find useful if I upgrade later on. 9. Portability. Little maintenance. 10. A nice sound when I take a shot haha What I envision myself doing is going out on the town, nature and taking shots. I'm planning a motorcycle trip on the grand american trail so I'd prob want to take it with me there. But I also have some ideas for basic documentaries I want to explore. So video is important.

I personally would get a system you could change lenses on, because for me it seems more economical to invest in glass you can use later down the line. The lens on the FZ, as nice as it is, won't come off when time comes to replace the body. Plus the sensor is kinda small and not awesome. For all your requirements I think I'd look into a GH3 used maybe.

The basic tradeoff you're going to make with a superzoom-type camera is image quality vs. zoom length. Now, the FZ200 will by no means be bad, but you're going to give up a couple of levels of high ISO usage as well as detail to something like a Micro 4/3rds camera, which has a substantially larger sensor. On the other hand, a 600mm F2.8 equivalent lens would be impossible to replicate on an interchangeable lens camera within your budget. So, there's the decision to make. Within your budget you could get a current-gen Micro 4/3rds camera and two very decent kit lenses with options for expansion in the future.

Did you not use the G9 because it was annoying to use or because you just didn't feel like taking photos? If it was the latter then spend as little as possible because you probably still won't bother to take photos. If it was because you were unhappy with the camera then for the love of god do not buy a lovely bridge camera. I would recommend you look into the OMD E-M10, it's at the upper end of your budget but hits all the points you want.

It certainly wasn't because I didn't feel like taking photos. I could expand my budget but I was trying to be reasonable. I'm going to take some more time to wait for more input and do some more research. I'm definitely not in a hurry.

Hope it's the right thread for this question. Was cleaning out the closet, found these old SLR cameras in the stuff my mom left me after selling the house. I looked them up on ebay, and they don't look like they're worth a whole lot. I don't know anything about photography, so googling the specs of these lenses just gives me more specs, which I don't understand. 1. Are these lenses any good? 2. Can these lenses be used on a DSLR?   (Pictures are on tinypic, imgur wasn't working for me, so hope these load okay.) I have a friend who just got a DSLR recently (not sure what brand), and if the lenses aren't crap I'd like to give them to her, if they're DSLR compatible. If they're not DSLR compatible, I'd give the cameras to a local college with a darkroom or something. I'm not looking to make any money off them, I just don't want to see them wasted if they're decent. Thanks.

No. The Canon lens is the standard kit lens crap that comes with the camera. It takes pictures but it's not real great. Modern kit lenses have come a long, long way in the last 10 years. The Quantaray is a knock-off third party execution of the same idea (for Nikon) 2. Probably. Either of them will probably mount and run, but they'll have their rear end handed to them by the kit lenses nowadays. Of course you can still run film through them. You can pick up a 50/1.8 for either mount for like $100, so the body might be useful to a photo school.

Both lenses are autofocus (AF) lenses from the mid-1990's, built for the consumer / entry-level SLR market. They're what are often refered to as "kit lenses", sold as a package with the camera and engineered for low cost above most other priorities. That's not to say those are bad lenses - by that era, few really bad lenses were being made anymore, they just won't stand out in any way. As for compatibility - the good news is those are both AF lenses. That means a modern DSLR is likely to be able to use one of them. If your friend has a Canon DSLR, that Canon lens will work on her camera. Similarly, if your friend has a Nikon DSLR it can probably wear that Quantaray. Canon's EOS series and EF lenses are fully compatible with modern Canon DSLRs. I know there are some complexities with Nikon, though, so if your friend has a Nikon DSLR please let us know the model (the Nikon you showed us is the N50 - look for the name of the camera in the same spot), others more familiar with Nikon will be able to fill in the details there. The other consideration with cameras of that era is batteries. For some reason, almost every camera of that era (and still to this day, to some extent) used weird-rear end specialized batteries. That makes them less attractive if the battery is some oddball expensive thing. A quick look at ebay suggests you might reasonably ask $50 for either camera. That further suggests a local college or high school or whatever with a darkroom would probably appreciate them but they probably wouldn't be over the moon about the gift - decent, basic cameras to learn the basics of photography on, but cheap and widely available. If your friend's DSLR is neither Canon nor Nikon (Pentax, Olympus, Sony, etc.) then all bets are off - she won't be able to use either lens. tl/dr: invite your friend over to try them on her camera (it will be rapidly obvious if the lens won't fit, and no damage to anything will happen for the trying unless you're an ogre). Donate at least one of them to your local college. They're decent, but not outstanding.

Thank you for the detailed explanations, ExecuDork and Paul MaudDib! ExecuDork, thank you for explaining like I'm 5 years old, that's exactly what I was looking for.  I'll definitely be donating that Canon. Would the Quantaray fit a Nikon D7100? That's the camera my friend has, but she lives 5 hours away so I don't want to mail it if it's no good for her.

The Nikon D7100 has the AF motor in the body, which means it can autofocus that lens and meter with it and do all the things a camera body does when it's talking to a lens. I think. Better get confirmation.
