Tamron AF 70-300mm VC USD - Poll

It never seems to get a bad review, maybe if Ricoh/Pentax reach 5% market share they'll bring it out in Pentax fit. http://www.shutterbug.com/content/tamron%E2%80%99s-sp-af70-300mm-f4-56-di-vc-usd-ultrasonic-silent-drive%E2%80%94quiet-fast-autofocusing "In Conclusion This lens blew me away. I...

Tamron AF 70-300mm VC USD - Poll

Well John, have to say that if the lens was available in Pentax mount I would definately .... go for a DA 55-300mm. The Tamron is ok up to around 200mm but after that it's average at best. AF is pretty slow as well. I am going to have another play tomorrow but get the feeling it will be going bac...

Lens Advice...for fun!

I realise that asking for advise is opening up a thousand views and a lens choice is subjective, but just for fun, what do you suggest I buy next? I have a k200d with DA18-55 II kit and DA55-300 and have been browsing the web for my next lens. I did have a FA28-80 F3.5-5.6 and a sigma 70-300 and an ...

Lens Advice...for fun!

Well I've taken the plunge. My lens should arrive on Friday. I listened to the advice about a wide prime (and I am very keen to get my hands on one), but realising my style of photography is "ad hoc" and when I have my 18-55 on I need more tele and with the 55-300 I need more wide, I have settled fo...

Tamron 70-300 vs Sigma 135-400

I found the Tamron 70-300 needed to be stopped down a lot to get anything half decent. @300mm I was finding my copy needed to be stopped down to f11 to get the best of it. I don't think you should avoid or select a lens based on cost alone. If you get the right one first time it could well be ch...

Tamron 70-300 vs Sigma 135-400

Thanks guys. A 25% crop is probably not worth the extra money. Maybe I'll consider the Bigma in the future. I found the Tamron 70-300 needed to be stopped down a lot to get anything half decent. @300mm I was finding my copy needed to be stopped down to f11 to get the best of it. I don't think...

LBA - Kit Lens

The DA*16-50 is very nice and I use it as a walkabout lens (although it's neither light nor inconspicuous). I have to confess I do sometimes long for a little bit of extra reach, but this is usually solved by using my legs. There were a few issues reported with the DA*16-50 (including auto-focus ...

LBA - Kit Lens

Get yourself a fast prime and never look back. A 50/1.7 is a good cheap choice. FA43 Limited is the pinnacle.

Good Lens Comparison Website

If you normally pick your lenses by looking at the price tags or talk a lot of nonsense... this isn't for you :mrgreen: Choose the lens and aperture of two lenses... sit back and be Amazed! Mouseover to toggle between the two lenses. Make sure the two cameras are the same. Sadly no Pen...

Good Lens Comparison Website

I tend to get a 100% crop on the film bodies ;) The Zeiss is not the easiest lens to use and takes a little getting used to. It is similar in behaviour to the 50/1.5 Sonnar. There is no floating element so there is a slight focus shift as you stop down. Many reviews do not compensate for this. ...

A few q's about the Sigma 30mm, eBay and Sigma sevice before I buy...

Hi everyone, I've just noticed GW camera on ebay has a very good price for the Sigma 30mm f/1.4 - its £299.99 and with full 3 year Sigma warranty, this is a full £70-80 cheaper than other retailers, so I guess I'm feeling a little cautious, perhaps overly lol 1. Has anyone bought anything from...

Just on point three: There has been an explosion of users on web forums claiming they have a 'bad copy' of a lens. This is largely users who frankly do not fully know what they are doing..many web stories are false. This leaves sellers in an impossible situation sometimes. A thread on here rec...

Thanks steve, I completely know what you're saying. I've never had a bad copy of a lens too. looking at some out of focus shots with the Sigma 30mm 1.4, it looks like a lot of it is user error, some people have done focus and recompose, which doesn't work well with the thin dof that 1.4 gives. Th...

There are a few issues there that are interesting. Decentering: I've seen decentering figures in the past and even 15% decentering can give good results, depending on the actual lens design. It may be less than the potential, but a great lens decentered 15% will be better potentially than a poor...

Seems to be a lense you either love or hate ... I love it ! +1 I have one and have been very impressed with it. While I'm sure that there have been some quality control issues, I'd concur with John's view that at least some of the negative reviews are down to user error/unrealistc expectati...

Manual focus: I can't agree that f1.4 lenses are difficult to focus, that one's a complete mystery to me. The limited DOF means that the sharp point snaps in and out beautifully and alo the brighter image makes it easier as well. When you stop down to f8 or whatever, all that's happened is that the ...

A few q's about the Sigma 30mm, eBay and Sigma sevice before I buy...

It's not that 1.4 lenses are difficult to focus it's that at apertures like 1.4 the viewfinder can't show a DOF that narrow, so you can be out of focus even though it looks in focus through the viewfinder. I showed this effect to a shooting buddy recently with my Pentax A 50/1.2. I got him to loo...
