Is it worth getting a Sigma 150-500mm f5-6.3 DG OS HSM Lens
I have the 50-500 as well. AF isn't lightning fast and it tends to hunt a bit when trying to lock on a distant moving subject. Focussing is quiet enough for me. Another advantage is that it saves you some money because you don't have to visit the gym anymore :) But you have to test your len...

Is it worth getting a Sigma 150-500mm f5-6.3 DG OS HSM Lens
I like the 150-500mm... I have been taking some great shots with it. I don't know what the AF is like as my ist-DL doesn't support HSM autofocus. In any case I pre-focus when shooting action of bikes and cars. This weekend I am heading out to Bruntingthorpe for a Subaura Charity track day and...

Is it worth getting a Sigma 150-500mm f5-6.3 DG OS HSM Lens
I recently borrowed a 150-500 and used it with my K20 at Duxford recently for some aircraft photos. I found that images up to around 370mm were usuable but the few I took at 400mm and over were very soft and in the whole I was disappointed with it's performance so I was glad to give it back. As Sc...

Is it worth getting a Sigma 150-500mm f5-6.3 DG OS HSM Lens
Hi Paul I too have a 150-500 and I am quite pleased with it for the price. A few images - Bear in mind that the street price is about £750 against the 60-250 at £1100, and it starts to look quite reasonable especially when you need the extra range. I have the 60-250 as well, ...

Sigma 28-70mm F2.8 EX DG
I thought about getting that lens but went for the Tamron 28-75 f2.8 instead. I can't compare the two but I am really happy with my Tamron and it is also full frame so using it on my new film camera to get 18-50 equivalent. Think you got your crop factors mixed up a little there! A 28-75mm full fram...

Sigma 28-70mm F2.8 EX DG
hmmm... 28-70mm: f2.8 at 70mm vs f4 for the 17-70mm also probably half the price! so if the idea is to get a decent portrait lens (to replace my 50mm as i am constantly out of focus!), would that make sense to get the 28-70mm?

Sigma 28-70mm F2.8 EX DG
yeah well i guess i just want a decent portrait lens i.e 40-70mm so the idea is to be able to use it at 2.8! i really struggle taking pictures in focus with my manual lens and my 18-250mm does a decent job but would like to find somewhere in between (autofocus / sharp). I've never tried the 17-70mm,...

Help required from those with knowledge of fa/faj lenses
Hi all, as i'm off on a motorcycle trackday soon i need a little more reach than my 50-200 gives, my local independant camera shop has both an FAJ 75-300 and an FA 100-300, both cheap as chips in good nick, both seem to be the same speed (5.8 @ 300). Now i know that the FA is a slightly older lens ...

Help required from those with knowledge of fa/faj lenses
Thanks Hefty, thats about what I thought - nice to have it confirmed. Just been looking on the lens database over on pentaxforums and the 100-300 gets a slightly better review, think i will head down with the camera tomorrow and try both. (theres also a 500mm mirror in there i'll have a try with to...

Help required from those with knowledge of fa/faj lenses
Telstar - I've got both lens. In my experience the FAJ 75-300 is good in the mid range - 135/150 area but not hot in the upper range. I got mine in March/April 06 bundled with an MZ60. It travelled with me as the long zoom option for the MZ50/iST film cameras when we went to Aus/NZ in late 06 and h...

Help required from those with knowledge of fa/faj lenses
Thanks for all the help guys, just back from having a play with the lenses. In the end didnt go for either, took the mirror lens instead! Its a Ranger branded one, made in japan, seems better quality than the centon ones ive looked at before. It was cheap anyway so not that bothered, i'll just hav...

The Sigma 28-200 has a very short throw on it's focus, which makes it a pain to focus manually but lightning fast in AF. I imagine it would make a good "traveling light" walking around pair with the 12-24, even if that combination does initially seem unusual since you're paring one of the best le...

Hi Emma there are a lot of landscape lenses out there Take the DA16-45mm second hand maybe around (£170) / or Sigma 10-20mm £300ish sigma's 18-50mm and 17-70mm about £300 .There is also a DA17-70mm but it's quite expensive at the moment. Also good to note that you have a Pentax camera which open...

TeleConverters fro Tamron 70-300?
Thanks for that. Auto focus doesn't bother me too much as I shouldn't be in too much of a rush when I'm at that zoom. So manual may be ok. Is it possible to Auto focus then correct manually?

Takumar lenses?
The sad thing is that original Takumars were the very pinnacle of Japanese lens-making. They were superb both optically and mechanically. If you can get hold of a good 55mm SMC Tak you will find the focus ring moves like silk lubricated with purest Jersey cream. Makes me salivate just thinkin...

Takumar lenses?
The Takumar (bayonet) lenses were in fact coated, with conventional coatings and not the SMC treatment. I stand corrected! In my defence I've never actually owned one :wink: The sad thing is that original Takumars were the very pinnacle of Japanese lens-making. They were superb both optically an...

Are all mounts equal?
To a certain extent yes, but remember that all cameras are different so what may be a punchy, saturated photo on a Canon is probably more due to the characteristics of Canon than the lens, though the reviewer, not having tried the lens on a different mount, may not realise this. Also what may work w...

Are all mounts equal?
I think the question was an interesting one, even though the intent was slightly different. This has turned out to be a discussion as to whether lenses behave equally in all mount versions. The question of the mount is interesting in another way as well, as the Pentax K bayonet mount has proved i...

Are all mounts equal?
It could be argued that the K mount that we all know and love has become a bit of an albatross around the neck of Pentax. Why, because the vast number of compatible lenses in the market that Pentax use as a selling point, actually harms them when it comes to selling new lenses. The DA designed f...
