Lenses / Re: Using EF-S lens on FF body???
« on: July 24, 2011, 05:43:49 AM »
This may be my interpretation only (so don't wreck your camera trying, please), only Canon-brand EF-S lenses protrude deeper into the body than EF lenses.
3rd-party brands have a smaller image circle, definitely, but they don't protrude any deeper than an EF lens?

When you think about it, only canon have the dedicated shorter-mount, no other camera does. If you build a lens for a Nikon, Canon, Pentax, Olympus body, and sell it with different mounts and electrical contacts only, you make the lens fittable to the longest mount (generally Nikon F) and don't change the optical formula for the other brands. Even Nikon DX lenses fit FX bodies (i think) without breaking a FF mirror.

So I would not be surprised if any 3rd-party aps-c only lens fits a 5d/1d/s (as long as it's not a canon-specific non-canon-brand lens).

But i would still be very careful, mirror-lockup/liveview can turn itself off at any time, as noted (i always forget to change the time-out on my camera when manual-focussing with liveview, until the screen goes black and mirror flaps down, then i remember)

Canon General / Re: What?? A SCAM INVOLVING A CANON T3i??
« on: July 24, 2011, 05:30:03 AM »
I've never had any dealing with craigslist, being an aussie, but i've seen a few on ebay (which does pride itself on having cleaned up a lot of scams compared to when it started).

i saw an EF 14/2.8 going for cheap, starting at $1 auction, and put it on my watchlist. I would have bid on it, but the seller was in Thailand, with a 0 feedback rating (auction was in aussie dollars, and listed on ebay.com.au). It finished around $1400 (c.f. B&H new price $2300), and I kept it in my watch list. Whoever the buyer was, they never left positive feedback to the seller, not sure if they received it or not. Either way, after a few months, the seller was listed as 'no longer a registered user'. I know ebay say you're protected, but generally only $400, and with fees and whatnot you never get back the full amount.

Same thing recently, a Zeiss T* 35/2 went for $757, to a seller from china with 0 rating. I was planning to watch the item again for a few months to see if it had a happy ending, but it seems not already, the seller is -1 feedback with the comment "This seller sold the item through another netshop the day after I won the bid". So at the least it looks like this buyer didn't lose any money.
It's a bit similar to the craglist scam though, could have easily turned into a "but i've got another lens i can sell you...".

long story short, always check feedback from sellers, especially if you're handing over a lot of cash (only pay $1-2 max for every positive feedback they've got is my rule).
and if it's too good to be true, it normally is...

Landscape / Re: HDR bracketing
« on: July 22, 2011, 08:34:22 PM »
in M mode, rotating the quick control dial (the 'dial on the rear') adjusts the aperture.  For HDR, you need to keep the aperture constant to have the same DoF in all your shots.  So, in M mode, rotate the main dial (the one behind the shutter button) to adjust shutter speed.

Not on my 7D, it was the first custom function i changed. In Tv the dial by the shutter changes time, in Av and M the dial does aperture, and in M the wheel on the back does time. Can a 60D or lower do this? (real question, not rhetorical).

it doesn't take much to just add it to other bodies.

No, it doesn't. But a 1Ds3 is 2-3x the price of a 5D2 with the same sensor. They have to justify the price differential somehow, like using better AF, built like a tank, more 'little' features. This is one of those nice 'little' features, not worth a grand on its own, but they all add up...

Few professional photographers will touch concerts with a barge pole.  Hundreds of kids who would like to break into photography shoot concerts for free, some of them are better than others.

I've known a guy who complained about that exact thing. He said he used to get invited to a lot of gigs, take decent photos (i hope he won't mind me sharing a link to an example that i quite like), and got paid decent money.
Then a few years ago, that all changed, kiddies with new cameras were promising to take photos just to get into the gigs for free, and his work dried up. Ironic thing is, that now he's getting more invites now, because those kiddies had no talent, they were 'just fans' (to quote from Almost Famous) who wanted to see the gig free, and the promoters have realised they have to pay for really good work...

Canon EF-S and EF-M Lenses / Re: Canon 15-85mm f/3.5-5.6 IS USM
« on: July 22, 2011, 07:51:49 PM »
How's the vignetting at 15mm? In another thread we were discussing, that vignetting on my lens is a lot worse on one side than the other, could be a centering issue. I haven't had any IQ issues (nothing better to compare it to though), i'd be interested to see how a refurb fares...
(and i'll put some pics up on here too one day, but i've taken a *lot* with this lens...)

Am i the only one who read the OP and didn't read any whingeing? sure, a few complaints that we've all heard before, but the post ended with "what do other people think of nikons, if you've use them?".

but then, this is the internet, and i wonder how many people read the post instead of just reading the title and getting enraged automatically.
perhaps a better thread title would have been "switching to nikon?".

ps, for whoever wrote that long rant: use grammar and punctuation. Long sentences make you sound like a teenager getting upset and your point gets missed. If the monologue in my head as i read sounds like an old woman yabbering in my head without taking a breath, then i'm going to ignore it just as much. And i highly doubt i'm the only one...

4) Leica M9, Fullframe sensor, really short flange distance, patented mirror thing on sensor to overcome angle of incidence problem, really nice glass, but have to sell your EF 800mm to buy one...

go nikon.
the more competition, the better it is for us consumers, both in price and innovation.
i'd be presuming nikon will be making an adapter to mount their F-mount SLR lenses.
But what? No Screw? No in-body AF motor? We won't be able to AF with our 20-year old F-mount lenses without motors in the lenses?  :o ::)

and 1/2.5" sensor? ouch, nikon, ouch. i'd buy a u4/3 PEN before i think of that, if i was all but the biggest die-hard nikon fan...

OK, here is a competition.... If we close an eye for the incorrect King/Queen setup, it's actually Nikon to move, and it has a forced mate in 3 moves !!! The one who find it first wins the chess set + T-shirt !
black moves pawn
white moves pawn
black moves pawn
white moves pawn
black moves pawn
boss comes in
boss sees lenses
boss screams
white tips over king, resigns, and runs away
black wins

Macro / Re: Super Macro
« on: July 22, 2011, 05:40:31 AM »
i set my aperture manually in f11 and hold the DOF botton while holding the DOF botton i release the kitlens in the body so that the lens is set in the aperture f11

is that actually good for the lens? i read (i think in the lens manual) that removing the lens while the IS is active can break stuff so i've always been really careful to switch the camera off (even when changing manual lenses).
Have you had any problems removing the lens with the DOF active though?

i've got a reversal adapter 62mm to Pentacon Six mount, then a P6 to EF tilt adaptor (so you get the advantage of tilt), but never really used it much, i'll have to try it one day if i can get shots that good with it...

Hello I want to share my macro shots using a reverse kitlens

Nice shots! did you use one of those fancy reversal adapters that you can control the aperture?

Hi, Maybe we should have a competition to see who can correctly name all the lenses which are on the chess board.

Quote from: Lensrentals
The complete 32 piece set includes 70-200 f/2.8 pawns, 600mm f/4 Kings and 500mm f4 Queens, 400mm f/2.8 Bishops, 300mm f/2.8 Knights, and 200mm f/2.0 Rooks in black (Nikon) and white (Canon).

I win. Or is it cheating copying their site?

meanwhile, how much fatter does the nikon 200/2.0 look compared to the canon, or is it just the angle?

I know I will be dating myself to some newer photographers, but when I was in college, at the beginning of the digital revolution, my school had several Nikon D1x's and only a few Canon D30's...

Dating yourself? i think you're dating yourself young, and at a rich school to boot.
My school's photography lab consisted of a bunch of film cameras, i thought slr, but could be rangefinder, i think olympus, i know they had selenium light-meters in a circle around the lens (although now all i can picture in my head is my dad's Petri 7S).
When i was at the end of highschool (finished 2000), they forked out a mint for a digital camera, i think i was allowed to touch it once. It had a freakin 1.44mb floppy drive in the back (which says a lot about the camera size, and image size too).

And i was at one of the most expensive (top-5) private schools in the state, $8000 a year it (should have) cost my parents (i was on a scholarship). We had a nice darkroom, and i think that beat every other school's facilities as it was...

I'd say that looks like some kind of a Hawk Moth, but i'm not sure if you get them over in the States. (I'll break out my backup hdd later and find an old pic i'm thinking of that looks like the one you've got there).

Got a shot of face-on to see the fangs better? I've no idea what they could be...
