Sigma 150mm macro
[quote:838a6bb6e6="Mannesty"]Clarky, You know George is right, he's always right :lol: If I hadn't just shelled out for the Sigma (poor substitute) I'd have a go at it. That lens is arguably one of the finest on this planet, and the next. As the advert goes, If Carlsberg made lenses, they...

Sigma 150mm macro
I would need a 49-72mm step ring if i want to use my AF-080C You got me thinking sometime ago when you mentioned making a macro flash bracket but gave up when it became too cumbersome. I have a couple of dinky little AF-160 flashes and decided to make a bracket to hold these. (Not sure if these...

Pentax F 35-135 Zoom Comments Please
Interestingly, Stan's photography pages has no comments about this lens. I like mine but like George, I don't use it much any more, but I don't agree that it's not a useful length range for digital. I just have others that are better... Hi Peter ... I see that you have the fa 80-320 in your arsenal....

Pentax 75-300mm vs Tamron 70-300mm
Nice John. I'm very interested in this - since I have the Pentax model. I use it a lot for wildlife(zoo) shots. Most of my pictures are around 200-300 mm - so I would love to see some test shots off these lenghts. Another thing - I had a UV filter mounted (a ca*** one). I removed it now - but hav...

What to buy... decisions, decisions...
I think Matt's talking about using a dremel or (very) sharp knife to slice off the outer holders, retaining just the one slot nearest the lens to hold the filter. I did this successfully on an 'A' holder (for a smaller diameter lens) and it worked quite well. I didn't think a P would fit the 10 - ...

http://www.7dayshop.com/catalog/default.php?cat=1&type=1330&man=0&filterwords=&go=SEARCH&comp= 7dayshop have got the filter holders for £5.50 and rings for £6, so not too pricey even if you buy an extra holder to butcher.

Screw Mount
Have been looking at buying a Macro lens but funds are a bit tight at the moment. Managed to bag a Vivitar 90mm 2/8 macro lens (actual lens pictured) on Ebay for what I think is a reasonable price to have a play with. From what I have read it is a true 1:1 Macro. It is M42 screw mount and c...

lens or body faulty?
Huh? That's why the centre black bar is so large - to filter out any focus point offset. The focus test chart at 45 degrees has such a huge and unmissable central target that the camera just has to get it. Ok, so the focus point may be a fraction out (looks less than 1mm for that view), but lookin...

When is a Pentax not a Pentax?
If you want fragile then the "F" series 50mm F1.7 auto focus is extremely fragile. The whole front where the filter would screw in is plastic. The number of these I've seen with ciplled, cracked or missing bits is very high. I kept a filter on one of mine just to keep the chips ...

When is a Pentax not a Pentax?
in what respect fragile George? mine seems very solid and well made, is there a weakness in these lenses I should watch out for? My first one was fragile in the sense that the aperture ring fell apart. I understand this is a weakness in early samples of the lens. There is a little spring clip tha...

Lens Help please ... Solved & broke!
Not sure how to answer for someone else's needs, but isn't the field of view of 135mm so close to 200mm that it would hardly make sense to add a 200mm? Unless there were other special requirements, I would probably go for the 300mm just to stretch out the range a bit. Oh yeah... and a second fo...

I'd generally agree with 'no filter' but if you want to work in a camera hostile environment such as sea spray, dust or sand then I use them.

I see that no filter seems to be the preference. What about on the 16-50 and 50-135 ? Yes or No or teh Pro1D protector?

The DA* 16-50 and the DA* 300 both take 77mm filters, so you can economise and share a filter between the two lenses.

If you really want to know what people think about filters, you should search for the several threads where the debate pro- and con- has raged. In summary: - evidence for actual image degradation (other than wide-angle vignetting) with a filter seems anecdotal at best - SMC coatings are to...
