a funny thought strike my mind ...how camera manufacturer position there DSLRs



D3100 & 1100D = noobs
550D & D5100 = Begineers
650D = Advance begineers
D7000 & 60D = enthusiast
D300s & 7D = advance enthusiast
D600 & 6D = advance begineer with lots of money
D700 & 5DMKII = enthusiast
D800 & 5DMKII = Semi Pro and enthusiast with lots of money
1Dx & D4 = PRO

D600 & 6D = advance begineer with lots of money

really funny...

600D with kit lens for 35k... a good deal from ebay...

@sujoyp

The RX100 is officialy available in India since over a month. Priced at Rs.34990 MRP.

 

[sujoyp]

Thanks @randomuser

bTW it seems u guys didnt notiiced the table...ok let me sort it out to a more understandable format

RX100
Sensor size - 13.2x8.8
Aperture - F1.8-4.9
Aperture in 35mm lens equivalent - F4.9-13.4

So it means f1.8 on 1inch sensor will perform like f4.9 on a full frame sensor ....thats bad

What? what? what? what? what did you say?

 

[sujoyp]

@nac its shown in the table check the link i gave...its written

Equivalent aperture, in 35mm film terms - this gives an idea of the depth of field control offered by the lenses when the sensor size is taken into account.

 

[nac]

Yeah, I see that...

Do you remember the thing I was talking about DOF, aperture a while back in the other thread???

 

[sujoyp]

u r talking about the discussion related to lens size and circumference with respect to sensor size...right??

but it still stays true..I dont remember specifically the topic.. .

the thing I know is camera manufactures cant increase the sensor size coz the size of the lens will also increase relatively....

Thats the sole reason sony RX1 came with full frame sensor and a fixed lens ...if it was easy they would have put a zoom lens there with 1.8 aperture afterall its a $3000 camera

 

[nac]

FZ60 and FZ200 are now available in India. Both are heavily priced 25k and 35k... 25k for FZ60 is toooo much.

u r talking about the discussion related to lens size and circumference with respect to sensor size...right??

Yes, it was about sensor size and how the aperture affects the DOF against different format cameras...

but it still stays true..I dont remember specifically the topic.. .

 

[sujoyp]

if FZ200 performs well as it was supposed then it will be a much better buy then canon's 50x zoom..

But if the constant f2.8 is a gimmik then thats too bad for photo enthusiasts.....

guys think that a canon 100-400 f4 (constant f4) cost more than a lakh and a nikon 70-200 2.8 lens cost 1.4 lakh and panasonic is giving a range from 24-600 f2.8

Guys, do you think you can measure the capabilities of a pro camera, such as SLR with a high end phone's camera? What is your views on this?

There is no comparison.. high end DSLR are in different league..

even entry level DSLR (like canon 1100/1000) are much better than high end camera phone..most important difference is because of sensor size and variety of lens available ..camera phone simply can not match the picture quality because of limitation of small sensor...

Mobile camera has improved a lot and nokia pureview and other high end cameras give very good pictures which will satisfy majority of people .But megapixel and good picture quality (in good sunlight) are not the only factors...what about ISO,low light performance,action/motion photography,RAW etc...

In my opinion advantage of mobile camera is that its always available.you don't have to plan to take your mobile with you.

Best phone camera is undoubtedly Nokia 808. It has been added in dpreview database so you can compare with other cams.

Studio shot comparison: Digital Photography Review

 

[sujoyp]

My opinion is camera phone can not be compared in optical zoom performance coz they have digital zoom which is as good as zooming a pic on PC.
And 2nd is low light performance...inside building or early morningg and after 6 in evening its just not usable ...and plzz that mini led flash is just good for horror shots and pranormal activity type videos

 

[marvelousprashant]

@sujoy Since audiophilic wanted to know about high end camera phone... I told him about 808.

1. It has lossless zoom (Not optical, but not digital too) Moreover it is silent and there is no loss in quality in good light
2. Low light/High ISO performance is better than cams like LX5 or S95/100
3. It has a very bright xenon flash... along with f/2.4 Carl Zeiss lens

If DSLR like 1100D is in Auto mode, the 808 will come surprisingly close

 

[audiophilic]

can anyone refer me to the 808 sample pictures.

 

[sujoyp]

@prashant so u mean if I put a 50mm 1.8 lens @ f2.8 on 1100D and compare it with a 808 pureview...808 can surprise me coz it have f2.4
Prashant u have fallen pray to marketing claims

......................................................................................................
Ok I did the comparison in dpreview...and it definitely look good in 8MP mode till ISO 200 ...and it give good fight to D3100 and 1100D untill that(in iso irrespective of lens used in the test. I feel that 38mp and 41mp mode is just useless...8 mp mode is good
After ISO 200 its very poor

Thanks for the links. BTW, great clear pictures, can't even say they were taken with a phone!

 

[marvelousprashant]

@Sujoy Surprise in the sense that a phone camera can produce such quality results... not that it will beat the DSLR

Also compare Sky, Tufa, and the evil Rabbitbrush #MonoLake | Flickr - Photo Sharing! and Nikon D800 :: Sky, Tufa, and Rabbitbrush | Flickr - Photo Sharing!

 

[sujoyp]

@prashant ...808 camera is really very good I should say...it can really replace a P&S ...but no optical zoom...and it seems it always take shot at f2.4 ....I saw all the samples at f2.4....
