Advice on Tamron 28-75 f2.8
This is about the Tamron AF 28-75mm f2.8 XR Di LD Aspherical (IF), a lens I am interested in and looking for guidance about it or alternatives. Here is the lens as listed on DPReview if you want more information ... Its clear enough that, if just thinking about the lens in isolation, that it of...

Advice on Tamron 28-75 f2.8
There are many answers Andrew, I didn't expect it to be easy :lol: Regarding focal lengths, I feel I need the 75 at f2.8 for quick portraits, and feel that having that as part of a zoom already on the camera in use for walkabout type shots will mean I'll bag more shots of both types reliably. So its...

Advice on Tamron 28-75 f2.8
Nigel, why don't you spend about 30 or 40 quid on a Pentax F 35-70mm f3.5 - 4.5. Try it its great. If you don't like it, you haven't lost much. i spend a lot of money on various lenses, but i always come back to this one. It works very well as a portrait lens on 70mm. The 35 mm is always wi...

Advice on Tamron 28-75 f2.8
Yes the F-35-70mm is fully auto focus and fit well to all Pentax cameras. Starting from the first K to the K3.. Regards, Horst

Good or bad lens?
Totally agree with Mike-P. The 16-45 is a cracking lens, But not that much better than a kit lens in my opinion. If you want to save a little. Just slightly wider and faster. 50mm 1.8 is a must for any low light work. The 55-300 DA or DAL is a great all round performer delivering decent results. The...

Lens mount query
I thought the Pentax power zoom designation was FAJ? And if you have one that doesn't work on (powerzoom bit of it) on a modern body can the drive motor be disengaged to allow manual movement with the focus ring? I'm wondering if this makes it too loose ...?

Lens mount query
Thanks John, do the powerzoom FA lenses have any specific extra letters to indicate the powerzoom feature? IIRC all the first FA zooms were PZ lenses (28-80, 28-105 & 100-300) to compliment the PZ features of the Z-1 & Z-10. It was only later that FA zooms were available without the PZ functionality...

Pentax DA 17-70 Vs Tamron SP 17-50
Strange isn't it - I know several members who share my view of the 17-70, one has bought and sold 3 for the same reason - whilst others rate it very highly - which in fact is why I bought it in the first place. John - Both my 16-45 and 17-70 have been owned from new. Both used on at least 3 diffe...

Pentax DA 17-70 Vs Tamron SP 17-50
I had a 17-70, but sold it after purchasing AndrewA's Sigma 17-70 F2.8-4 HSM OS. Here are my thoughts after using both lenses extensively: - The Pentax 17-70 is a fine lens but has focus issues with some camera bodies. By this I mean inconsistent focus, sometimes it's spot on, other times it i...

Pentax DA 17-70 Vs Tamron SP 17-50
I bought a 16-45mm and a Tamron 17-50 a while back. The Tamron was used and I couldn't set the right amount of adjustment to correct the focus issues. That being said I still found it a lot better than the Pentax 16-45. The construction to my mind was better, and images were cleaner and sharper.

Pentax DA 17-70 Vs Tamron SP 17-50
On the back of pictures I saw from David Trout and Cabstar, I bought the Pentax 16-50, and don't regret it. Doesn't see as much use as my 12-24 though

Lens advice.
I'm currently looking at my first UWA lens as well. I found the linked reviews below to be very useful, and have narrowed it down to one of the Sigma 10-20mms. With so little in the current price at SRS I'm thinking it might be worth the extra to get the HSM, constant aperture, and quick shift of th...

Lens advice.
I like my DA14, the Close Focus is a nice feature for interesting perspective shots, excellent solid metal build (as good if not better than my old FA43 Limited). Its sharp enough wide open but improves when stopped down. As mentioned, af f2.8 DOF can be an issue even with a wide angle lens. I wa...

Lens advice.
I went for the Sigma 10-20 f4-5.6. The f3.5 lens was a great deal heavier and took a lot longer to focus. For two lenses which are optically so similar it made sense to go with the lighter, cheaper, faster (AF wise) lens. Haven't had much opportunity to use it so far, but when I have it's been a v...

Wanted: broken FA80-320
I am looking for a sad, neglected FA80-320 that has a good 'back end'. So, a lens with fungus, or smashed elements, inability to focus, dodgy aperture blades - anything. My copy has been in pieces too long as the plastic posts that take the rear mount screws have fallen apart (fairly common alas...

Pentax AF 1.7x converter
It is for me :D The key is understanding what it is and what it can do. There is useful information , especially in the latest post in that thread. I use my manual focus lenses as manual focus lenses only and the reason for purchasing the AF adaptor is for a planned future purchase of a DA*30...

Pentax AF 1.7x converter
You just have to get used to how to use the x1.7 on the DA*300. It works very well once you know the trick. Just manually focus to just the far side of the subject, then use autofocus to do the rest. Works very fast that way. If you are focused in front of the subject then the combo will hunt lik...

Pentax
I have an older DA50-200 which has loads of issues focussing around the infinity point. My K20D tries to focus beyond infinity especially when the contrast levels are not all that high. When I was on vacation I had to use it in manual focus most of the time. Is this something which can be correcte...

Pentax
Some lenses, especially telephoto ones, do focus beyond infinity. This helps to compensate for a shifting infinity focus point with changes in ambient temperature. Later camera bodies than the K20D allow focus adjustments on up to 20 lenses to be stored in the camera memory.
