Amazon seem to have gone from one extreme to another with their packaging. My Sigma 150-600mm sport was packaged much the same and I ended up sending it back as I couldn't get a sharp picture from it. Replacement was also woefully packaged but was much better optically. Enjoy the lens Kris :D

Focus adjustment
I noticed that with my new toy -- the FA31 -- the focus was often not where I wanted it to be. For example, I photographed a portrait bust, and focused on the eyes, but the back of the hair was nice and sharp. So, I spent some time today testing and adjusting the lens for my K-3 and finally decide...

Focus adjustment
I don't think its that unusual, mine had a +3 but my 43mm had +8 on my old K3. They are better behaved on my new body but so long as they are sharp on your K3 after adjustment I wouldn't worry. The option would be to sent both lens and camera off for re-cal. but that maybe a bigger risk. How are ...

Focus adjustment
When I can nail the focus, I'm really liking it. More than the 43 which on APS-C is an odd focal length. The 31 is pretty close to a "standard" lens on APS-C. I'll load up my LX soon and try it out as it was supposed to be. K.

Focus adjustment
Life was so much harder on my K10d using the hack program and having to remember the values for different lenses as it only saved the one setting. Maybe someone has a magic method that makes calibrating easy, I always never feel confident I have nailed it but use my lenses mostly at small apert...

Maybe someone has a magic method that makes calibrating easy, Tripod focus chart at 45 degree natural light widest aperture single centre point AF point And the most important one : do 10 tests for each setting, making sure the lens has to focus from infinity or closest focus distance each ti...

Focus adjustment
Hi Kris There is no magic method, but at least with a prime lens you can nail the adjustment. I prefer setting on a tripod in good natural light and focusing on a subject with good contrast such as a magazine page with writing on it, set at a 45 degree angle. With zooms it's a nightmare as the ...

Ricehigh has a good method. Sadly Photobucket have messed up the photos in the article, but the text is there.... http://ricehigh.blogspot.com/2012/01/focus-adjust-k-5-and-pentax-af-lenses.html Be careful focussing at 45deg the spot focus can move about a bit. that can be folded vertical is ...

Focus adjustment
To make sure that the centre of the target is in line. Tie a piece of string to the tripod column and pull it through the centre line of the target. Twist the target until it lines up. --

Favourite Lens?
Favourite or most useful? I loved the 300mm F4 star lens but i use the newer 55 300mm PLM much mor as it is lighter, smaller and much quicker to focus.. I loved the tiny 15mm F4 Ltd but use the 20 40 Ltd much more and i don't miss the wide angle much.. I loved the 12mm to 24mm F4 wide angle...

New Pentax Lens Roadmap out
The Sigma 35mm f1.4 is a great lens but I personally found the AF to be suspect on the K1... that and the 31mm f1.8 is just awesome! I saw a review of the 35/1.4 - apparently CaNikon bodies also struggled with focussing - only the 'cross-type' sensors had any hope of working (any they're mostly clus...

New Pentax Lens Roadmap out
You can get any Pentax lens delivered tomorrow so no problem for buyers :shock: :wink: Also back to Ca-non the AF isn't fast enough on 50mm OK on 35mm.... https://youtu.be/qRNstPolN38?t=490 This video is very informative. You don't need AF tracking or multiple focus points. You can use an f...

do i need to change kit
Couple or three nice Pentax lenses out there; the 150-450 and DA* 300mm are the two I use for birding but the problem is that for anything other than large slow moving birds in flight, Pentax do not make a body that will handle small, fast flying birds and although I have quite a few decent shots ta...

do i need to change kit
Comparing a D500 with a K1 is probably unfair because of the file size etc but compare the actual important differences that makes the D500 an incredible BIF shooter A realistic comparison is a D500 vs K3 ll because they are quite ' comparable" as a camera overall, each having sime unique advan...

another user here frustrated with not being able to get a good 600mm lens from Tamron or sigma for wildlife to fit pentax, yes the 300 + 1.7 converter works well but it takes some work to get the focus right.

LX & film - Lenses for travel?
I suppose it depends on the nature of your travels, assuming landscape is your interest I suggest: If you can put up with the weight of the 35-105, I'd recommend it. Of all the mid range manual focus zooms that Pentax made, this is probably my favourite. My version of the 24 is the A versio...

LX & film - Lenses for travel?
Thanks for the replies. I've discounted the A35-105 on two counts: the size/weight and the fact the focus ring 'clunks' (probably due to the 'macro' setting it drops into as you focus closer) - takes away the magic somewhat. I also have a K135/2.5 but that's larger/heavier than the M135/3.5 and need...

Will this ME Super Lense work on a K-1?
The lens description includes AF, a feature not present on the ME super. If it has AF it will be compatible with the K-1 (The ancient ME-F being the only exception, and not one you're likely to come across). K mount is just about the most backwards compatible mount there is. AFAIK all K mount len...

Wildlife.
I currently use 55 - 300 PLM version which works much better than the old screw drive version which tended to hunt. See my gallery on here for examples including whales and dolphins, birdlife etc Compact and very quick indeed to auto focus. I've also owned the 300 star F4 which I too loved but fou...
