Wide Angle lens for Building & Architecture Photography.
Just yesterday I received in the post a Pentax SMC 28mm f/3.5 shift lens which should prove ideal for architecture photography. Possibly its not normally wide enough for APS-C though. Having said that, are you aware of the shift feature of the sensor when using liveview which can be used with any ...

Wide Angle lens for Building & Architecture Photography.
Thanks for the responses so far, they are all gratefully received. Attached you will find an image that I took with my 16-45mm lens recently which got me thinking of buying a new lens. The image has been reduced in size. The arches in the centre of the image are crisp and clear. However, the towe...

Replacement standard zoom
Hi all After managing to drop my 16-45 and bork the AF mechanism I'm after a replacement walk around standard zoom lens. I'm taking more and more photos in bad weather so I'm looking at the weather-sealed lenses, which I've not had any experience of. I'd be keen to hear opinions on whether t...

You poo-pood my comment
I was out with the family on Saturday in hilly terrain, lots of long views but plenty of distracting tree lines and tangly forest textures in behind. I found that by standing back from my portrait subjects and zooming in to 105mm, my backgrounds became less distracting because there was less to see ...

You poo-pood my comment
I quickly made this diagram to demonstrate the principle as I understand it. At the top is a telephoto shot and at the bottom is a wide angle shot. In both resultant images the subject would be the same size (it occupies the same proportion of the image, ie. the distance between the black l...

Ultra Wide Angle for K1
I need some advices, I want to buy one, but not spend more than 400 pounds. Please advise. Second hand and old ones are OK too. I don't need zoom I don't need auto focus.

Ultra Wide Angle for K1
As you don't mind manual focus I also think the Samyang 14mm would be a good choice. Personally I prefer auto focus so I went for the Sigma 12-24. A big slow lump but it does the job on the K1.

Ultra Wide Angle for K1
I personally have the Irix 15mm Firefly and love it. The build quality, the handling, the focus lock (such a brilliant idea!). At this focal length, you practically do not need to touch the focus. Mine is set and locked on the spot on infinity mark and most times I forget the focus ring is even...

The use of extenders in general
I'm confused ..... how can you have an AF adjustment of +2 with a manual focus lens?

The use of extenders in general
Hi, you do have to set an AF adjustment value for MF. It's because it controls the beep/green light trigger position. To make matters worse the beep (MF or AF) gets triggered in two positions, similar to DOF. One going into focus and one going out and to make matters even worse like DOF it's affecte...

The use of extenders in general
Glad that your sorted and other people aren't confused :shock: I'm a bit confused myself about what happens if I chose APPLY ALL to a lens that already has an ID in the database with the value set. The manual says that in that case it will use the APPLY ALL value, but what happens if I then use o...

55-300 PM Excellent review
I bought mine to take to The Caribbean in December when they did the firmware update for the K3. It is quiet, fast to focus and sharp with nice contrast. It would be nice if it let more light in f5.6 is at around 260mm. A third of the weight of my old F4 300mm and half the size. Suits my travel nee...

New DA55-300PLM on K70
Many thanks for all your comments and contributions. Interesting to see what you found about the PLM, Bill. I can certainly vouch for it being very fast and silent - so much so that you just don't notice what's happening - things just appear in focus as soon as you touch the back button or the ...

Basic Lens Kit for K-1
I only very recently joined the K-1 club and at the moment can not justify buying more lenses. However I was pleased to find that I had a few full-field lenses in my collection many of which I had not used for ages. Of these the following seem to be getting used currently with my K-1: Sigma 28-7...

Cheap lenses for portraits
Hello, I understand that what I am asking doesn't make much sense, but I don't make any money out of photography, so for me it doesn't make any sense to invest thousand of pounds after I bought the K1 :D Let's not take in consideration the manual focus for a moment, as it's something I am stil...

Cheap lenses for portraits
btw what's your opinion of the FA 50mm 1.4 focus on the K1? I did a good portrait session and eventually I decided to shoot a good amount of photos in MF because I was scared about the amount of focus failures.
