Should I buy a Pentax-A SMC 50mm F1.2 Lens?
It has arrived. I received the lens yesterday. It is in prestine condition. While I was waiting, I did some practice shots with my A-50mm f1.4 to lern about shooting wide open. This helped a lot. When the lens arrived, I went in to my backyard and made some test exposures. I found it easier t...

Run of K-mount Sigma 50-500 lenses to be produced
Owch. SRS were selling that at £799 last year. Great lens though with very handy close focus ability.

Pentax FA 35mm front/black focus issues?
So my FA 35mm came today and I have given it a try out. I'd read that it wasn't great at f2 but at f2.8 it was sharp so I was disappointed to be having soft images at f2.8. In fact, sharpness was only at f5.6. I don't know a lot about focus adjustment as I have never had to do it so I went into t...

Pentax FA 35mm front/black focus issues?
No experience of that lens Gareth, but as far as AF adjustment is concerned i need a +10 on a few of mine so as long as you get accurate AF at that setting I would not be concerned. The degree of AF adjustment needed will always depend on a camera/lens combo. A camera can be spot-on but the lens ...

Wide advice?
Yes, that's right, come on, keep it up guys .... forget natural light, its usually rubbish and your portraits will suffer with excessive contrast, blown highlights, poor depth of field, shadows half over the faces in the wrong places, one eye out of focus ..... plus you'll probably end up turning it...

Lens for portrait... Tamron 70-200 F2.8 or something else?
If you need the flexibility of a zoom, prefer FF compatibility and don't mind the size & weight then a 70-200mm makes sense. Many people prefer a small prime not just because of the size & weight but also because it allows for a more relaxed subject, which tends to happen when you're not pointing a...

DA 55 - 300 v DA* 50-135
I have both lenses and the 50-135 is a much better lens but the 55-300 is much lighter, so still has its place. My 50-135 has a failed SDM motor but I still haven't got around to getting it fixed. It is so good a lens that manual focus is a small price to pay for the quality of image it makes pos...

DA 55 - 300 v DA* 50-135
With my manual focus DA* 50-135 (failed SDM motor), I find portraits and landscapes are fine. The lens quality is still wonderful even if the focus is manual. (Don't tend to use burst fire mode on these subjects much anyway)

Goodness gracious me
Ref the original post, I thought I'd check just for the hell of it, and yes the manual focal length setting of my K3ii does indeed go up to 2000mm. These chaps take backward-compatibility seriously! That would work with many astro scopes. I've used my K-5 set to 1500mm (Tamron 500mm mirror on a 3...

I'm more interested in the FA*600/4.0 that the same seller has on Ebay but I don't fancy the accompanying hernia :oops: Seriously tempted by that ..... a very good price as well. I was salivating at that one too....but a manual focus FA*??:shock:

Says manual focus under the lens item specifics but I would imagine thats a mistake otherwise he would have mentioned it in the listing itself ...... wouldn't he?

Wide options for the K1
Food for thought! I recall reading there was a slight issue when mounting sigma lenses on the K1. I did hire one a while back and wanted to use my 24-70mm but was asked by Srs not to due to this issue.

Wide options for the K1
Going back to the original post, my favourite lens on film was the K 35mm F3.5, which was my 'bolted on' standard lens. Not so useful on APS-C where the compositional options aren't there on FOV. All the samples I've seen of this on digital including what I've shot show this to be just as sharp a...

Wide options for the K1
I have a Sigma 12-24mm but tbh I don't do much in the way of landscape so it has never been on the K-1 but it is apparently a full frame lens. Looking back on Flickr I found a couple of shots taken with it at 14mm and it's actually pretty good. I imagine 12mm is a bit mad on FF though. by , o...

New Pentax D-FA 70-200 f4
IMO Pentax should just remove the baffle on the DA* 60-250mm f4 and update the focus motor. One of the best lenses Pentax have made, compact and much better focal length.
