Right multiple replies so I'll answer like this.
Guys gals what ever don't get your nickers in a twist over a simple statement miss language police.lol!
Now it's shot with a 1ds markiii n 28-70mm L lens.
Shot is in focus but takes 3 presses to finally go ow yer click!
And no its not my only lense it's my lazy time lense lol.

Hey guys yep as the heading states my lenses doesn't always register that I pressed the shot button.iv cleaned the contacts but no go.
I know it mybe time to buy a new lense but this one has been my trusty friend for years.any thoughts ppl :(

It's f4 and it's manual focus only sorry.but takes fantastic photos.

Selling my asahi super takumar lens that's been adapted to canon eos ef - efs. No fungus or dust present and cosmetically fantastic.great lens that won't disappoint.
Looking at $250ono

Tameron 90mm macro on a 7d is an awesome piece of equipment and can be used for portraiture photography as well.

Hey mate I use a number of asahi takumar lenses.love the 50mm 1.4 but it's radioactive.the 50mm 1.8 is crisp but I prefer my helios 44 55mm f2.i also have the 135mm f2.5 serial number 43812, fantastic portrait lens and a 300mm f4 lens.which is ok.eouldnt suggest it for bird watching as its a 200° focus range and no auto.for a fast paced shoot ie street photography they are abit hard but for portraiture I recommend them.

The m42 lenses work great on canon cameras due to the positioning of the mirror.the old canon fd lenses work but a focus glassed adaptor is needed and that can ruin the glass quality.but I love the asahi range easy to clean and smooth focusing.now I own the asahi 50mm 1.4 (warning radiation) asahi 600mm 1.8, asahi 135mm 2.5 series two serial number 43812 better than the newer L series lens, asahi 300mm f4, helios 55mm f2 awesome boken can't be beat.just to name the must get vintage lens.welcome it's addictive but fun :)

Awesome thank you for that I'll look into it.i looked at the Kodak site but no help there :)

Hey guys I recently bought a ziess ikon ikonta medium format slr.its a 2x 36 mm. IV downloaded the manual of Google but it doesn't tell you what size film is required.
Just wondering the obvious what film size and where to purchase it?
Sorry it maybe a easy answer to some but this is a 1929 build camera n iv never used a slr before only dslr. I am going to enjoy the challenge :)

OK a tripod is a must in this type of photography along with a remote to avoid camera shake.
Now the stars always move with the earth rotation, not naked to the human eye but our dslr can pick it up.so 30 sec or less exposure is a must or the stars no longer are dots but over in shape.
why now f8? Yes generally shooting in f8 especially in landscape photography makes everything more in focus.but in star gazing since your subject is a black canvas you need as much light as possible . hence the fast f stop 1.4 or your shots at f8 will need an exposure of let's say 1 minute 30.as I stated before that's fare to long and that cluster of stars you see in the photo above can't be seen . I hope this helps you out but if not there are plenty of tutorials on the Web about this subject.

I'm looking into a row in a or samyang I just didn't know how they would preform.after seeing your shot which is fantastic by the way I think I'll purchase one.

When shooting stars you generally need f2.8 or faster and the can't be present as the stars aren't bright.when shooting the moon a high f stop helps because ur practically taking a photo of a light.

I totally agree why $750 when in stores they are still going for $3000 (aust) if it's too good to be true it probably is.

Well i know the new 7d mark ii was tested at the world cup so before Xmas that'll be released but as for the 5d range a little bird said early to mid next year.

Hey guys iv recently been looking up at the stars and been playing with the lenses that iv got.now I'm a Canon user (please that's not my problem ;) ).I know f stop is a big factor and unfortunately my wide angle lense is f4 17-40 mmL but I do have a 24-70mmL but I find 28mm isn't enough.iv also lately been playing with vintage lenses, what's that got to do with this subject you ask? Well while having a play I put my asahi pentax m42 mount 50mm f1.4 that's adapted to canon on and had some amazing results that I thought I wouldn't get but hey come out better than my L series lenses.maybe the speed? Now I'm looking at ruffle 17 mm at 1.4 can I dream? Do they even exist? IV only found wide lenses in that range at 28- 35mm.any help is appreciated.
