filters

[jann1033]

sorry, got the body, decided finaalllly on the lens so, next in line is filters but this should be a one ? deal( haha)

other than for scratch protection, since there are "filters" built in the camera and image processeing type software, is there really a "need" for filters now with digital? ( i have some i will use for the lens i have and can use but as far as buying more for the 62mm lens)

as always thanks

A polarizer (circular). Multi-coated if you can go for the $$$.
No other filters should be needed.

We must've been thinking on the same wavelenght...

I just finish reading

http://photonotes.org/articles/beginner-faq/misc.html

and coming here to ask a question...and lo and behold your "filters" thread..

sorry to hijack, but here's my question to the experienced SLR users:

I have 3 lenses

Kit 18-55mm uses 58mm filter
Canon 50mm uses 58mm filter
Sigma 18-200 uses 62mm filter

Given that the least expensive Hoya HMC UV is $30 and HMC Polarizer is $80, anyone know of any negative effect of using a 58-62 step up ring so I can get just one set of filter? UV is for protection so it'll be on most of the time. Polarizer is for when we go on sunny vacations

Thanks

evidnetly some one higher up is sick of my annoying ?? cause my posts keep drifting off to cyber space when i hit the submit button


no problem Sue..i wondered the same thing so it will keep me to my "1 question only" ( cept mine would be 62 lens, 55 filter which might be pushing it)

A 62 filter on a 58 lens should not be a problem as long as the stepup ring is a low profile type. You still might see some vignetting at 18mm.

On a wide angle lens a 55 filter on a 62-55 stepdown ring would likely cause vignetting. If you stack two filters it will quickly get worse.

An additional issue is the four air/glass surfaces which can cause flare and loss of contrast. I found when I used a UV filter I got too lazy to remove it when I went for the polarizer, and my photos suffered for it.

I always use filter (UV0, Hoya Super HMC... but not HMC Pro). Especially in pro applications where you have to run left and right. I've scratched several filters due to accidental rubbing, kids throwing pebbles to my lens etc. If not because of the filters, I would've changed my lenses at least three times for each lens I own and about five times on my Sigma 18-125.

My portrait lens is different (Canon 50mm f/1.8) because 1. the price of the filter = the price of the lens, 2. I only use that lens for portraits, so I don't really carry it around. I put it on my camera just before taking the pic and take it off right after.

Kids throwing pebbles? That's a rough crowd!

I *love* my "nifty fifty", for $65 it just can't be beat. This Alex, who I was sitting for, taken with the 50mm.

Yeah, weddings, gotta 'love' those kids. Choking them 'til they turn blue usually is not an option, unfortunately.
