Gear discussion thread v. "I got some new gear and I got to post it here" - General

The D7100 was $800, didn't think I was gonna have the money for it all but I managed to get it.

Just got my first camera, rebel T3. Really excited to learn more about photography and actually be able to record the places I go :v:

some fresh blood to sink my teeth into

[QUOTE=Trogdon;43307877]tried to reply to this earlier, guess it didn't go through. but for zoom lenses, the hood has to be designed for the wide end (in this case 70mm) because otherwise it would cause vignetting. so the petal design is to make it as deep as they possibly can, while cutting out the corners so there isn't vignetting. i was on my phone so it was a bit of a simple reply, but yeah it's a wide lens type of thing, meaning that it's designed with the wide end of zooms in mind and wide angle lenses, sorry to be too vague. primes 50mm and over usually never have petal hoods because theirs can be made deep enough without requiring a petal design i'd opt out of getting a third party hood (unless you really want a rubber hood) because they aren't specifically designed for one lens in mind, but rather a multitude of possible lenses. that and they usually aren't bayonet hoods, and if they are they still require some sort of base "screw in" part in order to be a regular bayonet. just a bit of a hassle really, i'd recommend buying a first party hood from somewhere like keh.com[/QUOTE] Well yeah I'd only get a bayonet mount one, but it doesn't appear that there are any petal shaped ones for this lens in particular. Ah well, suppose I'll go for the stock one.

Why does dynamic range decrease as ISO decreases? I thought lower ISOs had more dynamic range than higher ISOs. This goes together with why there can be more dynamic range in the jpegs from my X-E2 at ISO 800 than base ISO 200. [video=youtube;eOjmYDQmhok]http://www.youtube.com/watch?v=eOjmYDQmhok[/video]

ohhhh my grandfather saw my OM-10 and was like 'oh hey I have some olympus stuff lying around I don't use anymore'. So now I'm a proud owner of an OM-20 with another 50mm f/1.8 Zuiko (smoother focus) and a RMC Tokina 75-150mm f/3.8 also real smooth focus & zoom. Thanks grandpa!!

Got my PowerShot today, going to go shoot some stuff outside later today

Random question: Is the Canon EOS 3000 FF?

So my friend recently got a 600D with 15-55mm kit lens, and now he wants to start expanding his lens collection. I'm thinking the Canon EF-S 55-250mm would be a quite nice purchase. What do you guys think, what's the most useful lens to get after the basic kit one?

[QUOTE=ForceGhost;43317383]Random question: Is the Canon EOS 3000 FF?[/QUOTE] it's a film camera that takes 35mm film. full frame refers to cameras with a digital sensor the size of a frame of 35mm film. so in this case, i guess it physically has to be.

[video=youtube;eOjmYDQmhok]http://www.youtube.com/watch?v=eOjmYDQmhok[/video][/QUOTE] When ISO goes up, the sensor tries to be more sensitive to light, and as a consequence the brighter and darker points have less fine gradation between them so you lose dynamic range. The sensor's base ISO has the most dynamic range, and is usually 100 or 200 (50 is simulated by exposing at 100 then software dropping the exposure 1 stop, so it has less dynamic range). Video cameras measure ISO differently, it's called DB there. 0DB is the base, which is about ISO 800. I'm not entirely sure, but I think lower ISO's for video cameras are simulated and have less dynamic range because of it.

how long do you think it takes before someone grabs my d3100? One guy sent me an offer for $300, i didn't even reply to that shit heres the listing: [url]http://www.ebay.com/itm/Nikon-d3100-with-kit-Nikkor-VR-18-55mm-AND-Nikkor-35mm-f-1-8-/201009592922?pt=Digital_Cameras&hash=item2ecd1afa5a[/url]

[QUOTE=garychencool;43318469]how much 3dB one one camcorder will be different from another[/QUOTE] Is this not just due to the base ISO? db is a relative measure and without a reference point is completely meaningless. That's why you generally append a reference to it (dBSPL, dbV, dBu, dBm.. Etc.) From that reference point 3dB is a 3dB increase regardless of device or measurement. Is there not a standard like... dbISO (dB relative to ISO 100 - or something, 0db ISO100; 6dB ISO200, 30dB ISO3200)? What interests me though is do video cameras use Log10 (Used for Power) or Log20 (Used for things like SPL and voltage) dB measurements? If the latter, Applying my knowledge of dBs from audio, 6dB would mean twice the ISO? Genuinely curious, this is the first I've ever seen dBs used in a video context, audio is my thing so this post is probably full of crap :)

Pretty sure video DB does not work at all like audio, could be wrong though.

According to video maker, +3dB is equivalent to opening your lens about one f-stop. [url]http://www.videomaker.com/article/14280-making-video-in-low-light-conditions[/url] A lot of camcorders have fixed lenses and the ones with an interchangeable lens system are pretty expensive. A lot of camcorders with fixed or interchangeable lenses also have variable aperture lenses.

d7100 is coming tomorrow

[QUOTE=Desuh;43318142]Eh 50mm on crop is quite long. Maybe the new Sigma 30mm f/1.4?[/QUOTE] Maybe it's just me but I find the crop on a 50mm alright which can be useful in certain conditions. The nifty fifty for Canon (f/1.8 version of course) is pretty worth the $100. Hell you can even get it for less elsewhere or possibly second hand, just test the AF motors and inspect the glass. Just because it's plasticky it doesn't mean it's not good on your standards.

[QUOTE=codenamecueball;43318952]i'm selling my dslr for £300, it's £380 new[/QUOTE] sold my d5200 for $460 (which is pretty low), new ones are $520 on ebay with 1 year warranty (since grey market) [editline]26th December 2013[/editline] is there any lens I should get for $200 besides the 35 1.8g?

After a bit of reading it seems that ISO is used because ISO is a standard, ISO100 should be (I bet it isn't) ISO100 regardless of whether you're using a potato or 600D. However internally it all refers to the same thing, sensor gain. But as dB is a relative measurement and there's no standardised reference point for the use of dB in a video context (Which I find baffling! - We have PLENTY in audio) 0dB on one camera will be different to 0dB on another camera. BUT 6dB is the same increase regardless of camera because 6db is 6dB no matter what field you are in: 0dBV is 1V; 6dBV is 2V 0dBm is 1mW; 3dBm is 2mW But, if we had dBISO (That is, dB relative to ISO100) - My made up measurement: 0dB is ISO100, 6dB is ISO 200 As it stands camera A could use ISO 500 as a reference point and 6dB would be ISO1000 whereas camera B could use ISO 50 so 6dB would be ISO 100. Without knowing the camera's reference point for it's gain setting "+6dB" Means nothing. Sorry if this is completely irrelevant to anything I juts found it interesting. :v:

[QUOTE=codenamecueball;43318952]i'm selling my dslr for £300, it's £380 new[/QUOTE] does it have warranty??

If it's in very good condition, push for £320-350

What are you getting, cueball?
