Which Wide Prime?
There is no way on earth the 21mm will focus anything like 1 cm. I think you missed a zero, possibly 10cm. Mike 20cm to be exact. :wink: Are these metered from the sensor or lens-mount btw?

Which wide zoom?
If it's all very confused in your mind, I would suggest going back to basics. Just use your basic lens for a day or two's shooting, perhaps the 18-55mm, or whatever is normal in your set of lenses. Enjoy the photography and don't take any other lenses out with you. Then think about how often y...

Cheap Macro: Pentax KA fit Cosina 100mm F3.5
If anyone wants a cheap macro lens, seems the seller didn't think putting the word macro in the title would increase interest so he left it out :oops: :roll: Finishes: 21-Jun-09 18:58:02 BST With 23hrs to go £10.50 Pentax KA fit Cosina 100mm F3.5. This is a manual focus macro 1:2 lens, and ...

Pentax A* 400mm f2.8
Surely Paypal would not have refunded without inspecting it first, they must have found something in the investigation that favoured the buyer. :?: Paypal do nothing, I had a mobile returned once after the buyer started a dispute (because he changed his mind) and after a lot of hassle with Paypal th...

Whats my focal length!
Yeps only the angle of view (AOV) change but also some other things change as well since the circle of confusion (COC) is also smaller. COC is how big a spot can be before it becomes unsharp. With 35mm that is 0.029 mm with an APS-C sensor that is 0.018 mm. That means that the dof becomes small...

Whats my focal length!
What is the MZ-50 like? A little more basic and with a plastic lens mount instead of a metal one, it'd do the job though and should be very cheap! As a general rule in the MZ range the models with a single-digit name (MZ-3, 5, 6, 7 and S) are better then those with the double-digit names (MZ-10, 30,...

DA*200 anyone?
Danny, already tested the DA*60-250 6 months before it was in the shop. the f/4 is holding me back a lot and i wont sell the DA*50-135 since it's just perfect for portrait, 60mm is going to be too long since i'm struggling with 50mm already. The DA*50-135 is really here to stay. Since the DA*50-...

DA*200 anyone?
I will own up to having the DA*200. I agree with just about everything that others have said above. Its an excellent lens but, unless you need the stop difference then the DA*60-250 does out shine it. Very easy to get purple fringing when shooting high contrast / back lit subjects but post ...

DA*200 anyone?
Looks like I'm the only person here that has one, which I use for indoor event photography. I love the rendering of this lens, which is more old-style Pentax :) It's very sharp right across the frame at f2.8 and the bokeh is superb (reminding me of 60's or 70's lenses). It doesn't sharpen up hug...

Sigma 50-500
I have always wanted a Bigma but recently I have seen the prices increase massively until I spotted that they're much cheaper again in the US. 47 St Photo have them for $960/£585 which is a big saving on UK prices. Has anyone bought from the US recently and does anyone know how much the import d...

DA* 50-135 wow wow wow wow wow wow!!!!!!
What I will say whilst they are uploading are my initial reactions. 1) I will not miss loosing out on the 300mm end by not having the Tamron with me. The sheer resolving power is mind blowing! I took a few shots from the top of a hill, and cropped in and easilly pulled off similar results to what...

DA* 50-135 wow wow wow wow wow wow!!!!!!
Right, here we go: Just a quick example of why I'm impressed how far this lens can actually allow. The picture itself is nothing to write about, I'm just quite pleased with how versatile it can be: 135mm f8: Here is the shot of the pidgeon I was talking about - again, the shot is nothi...

DA* 50-135 wow wow wow wow wow wow!!!!!!
It depends on how you measure Bob but the number giving is from the sensor. I believe it's one meter though, at least got that feeling. Wonderful photos on flickr, like how IMGP0663 came out. Perhaps it's just me then! I do have an experiment I use when I get a new lens, I sit in the exact sam...

DA* 50-135 wow wow wow wow wow wow!!!!!!
It is a great lens, and probably my sharpest next to the FA50mm F1.4 But, and it is a but, I have recently had problems with it not focusing at all. However, either swap lens and swap back, or (today) manually focus in the first instance and it starts talking to the body. Still a bit of a pain, j...
