Nikon Canon lenses' true focal range or length on a consumer grade crop sensor DSLR

[ankanbads]

lol the fun facts are really funny.. XD

[cherieecoco]

I just got a Nikon D90..it says DX sensor. What does that mean? Could you help?please and thankyou..

[xoacatl]

im looking to upgrade my lens for my nikon d70s with the 24-70 or the 24-120. i have 70-300 and 18-70. how does the 24's rank with my others for photos in church with low light and some portrait....what's your suggestion

[Vik456]

Your videos are turning me into an Advanced Beast of a Photographer.. Thanks so much for all the tips.. I myself went from a canon s95 to Rebel T3 (just for starters) I'll give myself a couple months of learning till I step up to a Pro Camera.. Thanks again...

[jmattos]

Any idea what the crop factor is for the New sony a65 and a77?

[Handi360]

dose this count on dx lens's aswell?

[PhotographersOnUTube]

@Handi360 Yes, even a DX lens on a DX body would have the crop factor. As long as the body has the crop factor, the image will be cropped.

[MrCaRTom]

I am so lost and this may be a damn question to ask, but what is focal length or what is it used for? thanks!

[PhotographersOnUTube]

@MrCaRTom Focal length tells you how much area your lens will cover. When you get your kit lens it may say 18-55 or 18-105 which means your lens will cover from 18mm to 105mm.

[herman167]

hi, i got a Nikon p7000 and i can't figure out if i have a crop of full frame sensor:S any help? :)

[PhotographersOnUTube]

@herman167 Full frame cameras start with $2500 and up. D7000 is crop sensor

[onishchuk4]

@PhotographersOnUTube I think herman167 actually meant p7000 as it is a point and shoot nikon.

[notjustamoma]

Thanks.



[notjustamoma]

What is FX & DX?



[PhotographersOnUTube]

@notjustamoma It's a format and Nikon terminology. FX is your full frame and DX is your crop sensor.

[yanteshdhir]

Just wanna edit that if a Nikon Lens say DX at the end it has the same focal length on the crop sensor body as it is written on the lens. :D

[PhotographersOnUTube]

@yanteshdhir That would be  incorrect. DX lens on a crop sensor still gets cropped.

[yanteshdhir]

@PhotographersOnUTube Huh? Really? I am pretty sure someone on youtube mention it otherwise in their video. But thanx for correcting huge misunderstanding.

[PhotographersOnUTube]

@yanteshdhir You're right. There are people who say it but think about it... crop sensor. It's job is to crop the image. In my video "prime vs zoom vs kit lens" I used one DX lens and one FX lens at 50mm. You'll notice that they both give you the exact focal length. If you put a DX lens on an FX body, you'll lose almost half the pixel as the edges will get cropped.

[yanteshdhir]

@PhotographersOnUTube I understand what you mean to say . But I dont quite understand what you meant by "If you put a DX lens on an FX body, you'll lose almost half the pixel as the edges will get cropped. " Can you please explain this. I mean I know some vignetting occurs in full frame bodies but never understood why. Not only in Nikon but even Canon bodies. I have even seen Lieca's images getting vignetting.

[PhotographersOnUTube]

@yanteshdhir No, this is not vignetting. This is just like camera capturing picture mostly from the sweet spot of the lens. By doing that... things around it will be gone. When you crop the picture... what happens? You lose pixels. But this is not common because those who own FX bodies also own FX lenses. Those who own DX bodies but know eventually will go full frame also buy FX lenses only. I own 1 DX lens. When I go full frame, I'll sell it as I won't use it at all.

[benedictsalvacion]

hi sir, i am an emerging photographer in the Philippines and I love your videos for they are very informative. Would it be ok if you visit my works and leave a comment on how I am doing or I have to accept the fact that this isn;t for me... please leave an honest comment. I'm in a tight budget and was using d60 with kit lens only. I would greatly appreciate your comment and work from there. Thanks in advance!

[ZlleH]

LOL! Great video, but what a cliff hanger! Now I need to know what is the minimum shutter speed for my 50mm on my D7000! I'll feel like I'm going to take all wrong pictures until your next video! Very evil ;P

[PhotographersOnUTube]

@ZlleH Haha. The true focal length is 75mm on a crop sensor which means your minimum shutter speed is 1/75 sec. You should not fall bellow this speed or the pictures may look a bit soft and even blurry. Remember, it's minimum, not maximum. So if you're getting 1/125 sec speed on aperture, you're fine. In manual if you're not getting 1/75, then open up the aperture until you can reach 1/75 sec.

[ZlleH]

@PhotographersOnUTube Thanks! I'll try to change to keep it to at least 1/75 sec. But this rule goes out the door when doing nights shorts, fireworks, silky water effects, etc., since you need the shutter speed to be slower then 1/75 sec, correct?

[PhotographersOnUTube]

@ZlleH This rule goes out the door the second you place your camera on a tripod. Even if you're shooting during the day and you're not looking for silky water, you can still fall below your shutter speed. If that's the case, you put the camera on a tripod and you're good to go. The hood on my lens is Nikon's hood for 50 1.8 A link is posted on my site. It's collapsible for more space.

[ZlleH]

@PhotographersOnUTube BTW: Is the hood on your lens (guessing it's the 50mm 1.8) a Nikon hood or is it another brand?

[bpmuzik808]

so how about DX only lenses do they have to be multiplied also?

[PhotographersOnUTube]

@bpmuzik808 Yes, they do. It doesn't matter what lens format you have, DX or FX. If the camera is crop sensor, you have to use the crop factor and multiply by 1.5 for Nikon and 1.6 for Canon. There is one Canon crop sensor that's 1.3 crop factor.

[D3XsiBry914]

Heyy bryan here! me and my friend will go on nyc on july 4th? wanna come? just chill bry magsino here from plainfield :P just pm me on fb and lemme know (:

[8javed]

Whooaaa! That fact is so scary...and so sad. :~/

[PhotographersOnUTube]

@8javed You think this is scary. Some Olympus DLSRs have 2 times crop factor. Just image your minimum shutter speed for telephoto lens.

[8javed]

@PhotographersOnUTube I meant your 'Quick fun fact.' I'm not a very sophisticated photographer so I can't make any technical comments about professional cameras in general. :~D

[royappa]

I see, so you are basically saying 50mm is for portrait on crop sensor. on full frame, they should use 85mm or so? I recently sold on my lens (nikon 70-200 vr1,nikon 18-105)and kept only 35mm prime. 70-200 vr1 was too much for me and felt VR was over rated. shutter speed was alot more important issue.. at least for me. just ordered 2nd hand tamron 28-75 2.8 and planning on getting sigma 70-200 HSM 2 or tamron. but probably sigma.. when I cant get tamron to focus, optical quality isnt important.

[PhotographersOnUTube]

@royappa Well, if you mostly do portraits and space is not an issue then 85mm (crop or full frame sensor) is way better. The reason why 50 is more popular is #1 price, #2 you can still do small group shots and mid size group from distance. #3 It's very light so you can get a sharp picture even at 1/60. If you're not doing this for living the 3rd party lenses will do the job for you. Pros go for name because they can make the money back in 2 weddings. Tamron 28-75 and Sigma 70-200 are good lens

[royappa]

good video! hey i have a question. ppl say 50mm is a portrait lens. ok now, are we talking about this on a crop sensor or full frame? because 35mm on a crop sensor is a really around 52mm.. had this question for long time but didnt know who I should ask to and found u buddy!

[PhotographersOnUTube]

@royappa You definitely don't want to do portraits with a 35mm. #1 it costs more than 50mm #2 you're going to be so close to the people doing portraits that it will be very uncomfortable. 50mm is mostly popular among crop sensor owners. THE ultimate portrait lens is actually 85mm but because 50 1.8 is so cheap, almost everyone owns it. I wouldn't use 35mm if you me for free. 50mm in tight spaces or 85mm if you have enough space to work with.
