Photography: Camera sensor size difference

sorry if this is taking the level of conversation down a bit, but any of you have experience with pentax's dslrs? i'm considering upgrading and the k20d looks quite good from reviews/specs, but i've never used a pentax dslr (though always used a k1000 for film).

thanks

it's a very nice camera, get it mate, unless you're buying it in order to use your old pentax lens, then you might get caught short due to the crop sensor (my father did, end up getting a 30mm F/1.4 sigma to replace the nice Pentax 50mm F/1.4).

$270 for the adaptor ring to put Nikon's on a Canon body? Fuck that.

£99, not really, you can get a nice 50mm F/1.2 for about £120*, add the adaptor, £219 and bingo, still a lots cheaper than a brand new Nikon 50mm F/1.2 that sell for £700.

or get the Canon equation that sell for a staggering £1200, now £99 look promising.

*that if you look carefully, you can do a BIN for £250 on the bay.

that is only really an issue if it prevents you from handing something to your client that you are not happy with or the the piece of equipment is overpriced compared to the competition.
any other issues are for forum fanboys with a flickr account to discuss.

ahh music to my ear.

thanks ed

no, not necessarily looking to transfer the old lenses, just looking at the pentax since i don't like the button layout or in-the-hand feel of nikon's dslrs and the pentax seems better value for money that the canon 450d (and i've never been a fan of the rebel series).

Yeah - that's why I said I wasn't gonna start that argument. It's what you do with it that counts. Just like bikes, doesn't matter what you ride, it's about how fast you can make the fucker go.

any nikon people got the new nikkor af-s 50mm yet? want to find out if it's any good..

Aaaaaaaaaah. I see. Cheers.

Yeah ! What MrSmith said, so I can control aperture when shooting video (to control DOF).

• I have already got 5 or 6 Nikon Lenses.
  

exactly, kinda another reason why I got a Canon in the first place; best of both world.

Agreed.

Buy a Canon body and a decent NIK/EOS adaptor and you can use Canon and Nikon lenses.

You can get them for $6.

Question Photographengers . . . . .

I need a few filters, I don't really know what is good and what is bad quality when it comes to these things, I usually just end up with some overpriced piece of Jessops branded crap . .

So . . . I saw these, which seem pretty cheap (and are on a 3 for 2 off).

What do you all think, are they going to be cheap crap or are all filters pretty much the same ?

Anyone got any recommendations for a good source of good and cheap filters ?

Yours Sincerely.

hand held cokin filters FTW

I've used the nikon to canon and leica to canon adapters for a couple of years and they work great, think I paid like 30 € for both at the time...

I am going to have you put on 'the list'.

You dirty kiddly fiddler.

Are they cheap ?

if you buy them new not...pretty expensive...
but e-bay can be your friend...
lots of old school photographer selling them out. the cool thing is that they are pretty big (like 10x10 or 8x8cm) and the quality is amazing...and they have filters for anything..from basic color/light correction to what they call "creative" (read wird) effects...
I have a polarizer and a couple of gradient filters that I use quite a lot...

filters aren't all made the same. cheaper ones have lower quality coatings and are not multi coated.
the only one's i own are resin Lee nd-grads and a polariser (these weren't cheap about £60-£90 each) that are quite large to fit over large and medium format lenses. being resin they aren't coated but i use them with a bellows hood.
and some specialist filters 93mm diameter to fit my h/blad 40mm made by B&W
and loads of 75x75 cc, cto, ctb, nd and fl-d gel filters by kodak/lee for colour correcting different batches of film (halceyon days)

those filters in the link seem very cheap? are they single coated? if you use a good lenshood or matte box then multi coating probably essential.
as for skylight filters i always find they caused flare and have never bothered with them and don't know anyone who does.

cokin and lee are/were direct contestant in the market....quite the same resin and pigments.
to me the only use for skylight can be if you're a photojournalist/travel photographer working in very dusty places and you have to clean the front lens very often...at least you end up scratching the filter instead of the front lens..

Never used a skylight filter.
Flag the lens.

cokin and lee were not direct competitors. lee make bellows lens hoods which were way better than anything cokin made. originally cokin only had the 2 ranges (P and C?) the lee filters were bigger and the lenshoods/metal adapter rings better quality. Lee also made 100 and 75mm square 'gels' for colour correction from cc025 up to cc40 in red cyan blue yellow green magenta to colour balance film batches and fl-d, fl-t, nd and all the 80 81 82 etc series in abcde strengths. considering that a photographer who shot transparency would have to own most of these for proper colour correction (this is pre digital) then paying £5 each wasn't too much of a cost they also make rolls of lighting filters frosts etc. Lee stuff is used in the film motion picture industry (along with Rosco).
cokin is not on the same level. for example they only list one fld when you need the three that lee make to correct the three different kinds of fluro tube. lee also enable you to add a bit more magenta or green in cc.025 increments to fine tune, they also sell the lighting filters to correct the tubes in rolls long enough to cover a fluro tube.

Lee FTW!

actually is true, they've never been direct competitors, was me being a young and poor photographer when still shooting 4x5s... :((
(not that now I'm a rich one...at all!)
I got pissed off with Lee when they stopped producing their heavy frost in 2mt height a couple of years ago....was my favorite to build large screens. but I have to admit.. I'm still using the two lee compendium lens hoods after almost 10 yrs ...they are good...
by the way, never ever had the "luck" to shoot in neon lit environments....fortunately ;)

they do a 1.5m flexi frost rolls (otherwise known as nappy plastic) which are a bit bigger than the normal rolls.
by tubes i meant florescent not neon

I've seen that flexy frost...didn't like it..is quite different from the classic frost.. still have an old half of a 2mt roll for now and then i'll see..
never used florescent light...seen some in tv/movie studios and some fashion photoshoot but never had first hand experience... any good? I like mainly flash or daylight..
what kind of photography do you do?

see my homepage for my work.
kino's are o.k i don't use them much, they are available in tungsten or daylight.
i used to shoot a lot of retail interiors on film and learned to balance the mixed fluro/halogen lighting with a combination of different fld's and 80's and polaroid them to get the best colour, did enough of it to know what combination would work without using a CT meter and the trannies always came back with near neutral whites.
thankfully it's easier now with a computer which is why young photographers don't have as much knowledge of colour temperature and mired shifts as you don't really need to know all that stuff these days.

interesting conceptual still lives!
editorial or advertisement?
I've used quite a lot ct meters when assisting...working in hire studios with hired flashes...each head different reading. it was a mess!but learnt quite a lot about light quality.

"editorial or advertisement?"
anything that pays except porn, weddings or portraits.

Cheers for the info !

Matte box !? I am going 'bareback' (new photography term I just made up, write it down) - No lens hood or matte box for me, I like nothing more than flare and glare, you are talking to someone who puts fake chromatic aberration into his videos. :)

So . . . . (thanks for all the input by the way) . . . basically those cheapo filters I linked to look like they are probably not multicoated for that price . . .

Not being a filterphile I am probably best sticking to a good reputable brand ?

Any basic suggestions for a good solid (not too expensive) brand, that I can pick up in a camera shop (or online) . . . Hoya . . . Kokin . . . ?
