18-135 first impressions (on the K-5)
I have to say I sometimes noticed vignetting on mine as well. Doesn't seem to be consistant though which is a bit puzzling. It will depend on the focal length, and perhaps also the aperture and distance to the point of focus. G

18-135 first impressions (on the K-5)
I have to say I sometimes noticed vignetting on mine as well. Doesn't seem to be consistant though which is a bit puzzling. It will depend on the focal length, and perhaps also the aperture and distance to the point of focus. Indeed it does. I've just done a load of white wall shots, and stoppe...

A landscape prime
Both nice lenses, and useful focal lengths in different ways. However there is nothing else like the 15mm in manual lens world, whereas many 20mm and 24mm options exist. So I went for the 15mm. You don't gain much compared to a zoom like the 16-45mm in IQ terms, with either lens. You have to really ...

A landscape prime
If intended for landscape photos maybe you should look also for some good manual focus primes, like A20/2.8 or K20/4.....the latter is quite decent performer....better than K18 or DA 16-45 which I had. One downside si that it features 5 leaf apertures...so when shooting against the sun, you might ge...

What lens and camera setting do you use for butterflies?
It depends in part precisely what the nature is of the pic you want to take. The kit you have will be fine for getting some great shots. My technique is generally to have the camera in Av mode and set the aperture to be pretty small (i.e. a reasonably big f-number). With close-up work such as you mi...

What lens and camera setting do you use for butterflies?
I like to use my DA L 55-300mm for butterfly shots due to its great colour rendition and inherent sharpness, particularly at focal lengths between 100 and 250mm. The zoom gives great flexibility and the results have been very good. I find the autofocus is usually fine for butterflies, but I occasi...

Do you REALLY need more lenses?!
It's been quite a roller coaster ride for me since the day I bought my K-r. I bought it with the 18-55mm kit lens and an additional Tamron 70-300mm. I really wanted the extra length. From that point forward...it's been hectic. I was hooked once I learned I can get the older M42, K, M and A lense...

Do you REALLY need more lenses?!
Rather than another lens, what I want/need is a better way of taking my lenses & accessories with me, (and a newer Body!). My normal kit (in a large backpack) covers nearly everything (I've missed the 17-18mm range) from 10mm(fisheye)to 300mm in four overlapping zooms, together with a fast 50, a...

100mm lens as a telephoto
I am looking for a short telephoto to copliment my 35mm 50mm primes. I am looking at the various 100mm lenses but they all seem to be macro, are they suitable for telephoto usage still??? Any decent 100(ish)mm macro that can focus to infinity (and as far as I'm aware almost all of them - and certain...

DA 18-135 WR
It is a nice lens, ignore the measurebators. I have to say, my recent thread on my experiences with the 18-135 will be my last such, given the lack of interest, and suggestions like this. When helpful information such as "nice lens" is preferred to a fairly time-consuming exercise in photographin...

DA 18-135 WR
I continue to read threads on the 18-135 as it's an excellent focal range and the WR is an attraction - for my intended use corner softness etc as mentioned in the reviews could be an issue though as I do print up to 36x24 inch and have concerns how the prints may appear. Has anyone printed large ph...

If you had to choose - cast your votes please!
Strange that no one asked which version of the 28-80mm this was :shock: The smc version is very good, but awkward to manually focus because the focus mark on the lens varies depending on the focal length. I would have sold both and bought the Pentax-A 35-70mm f/4. There was also a Takumar v...

On the brink of LBA!!!
Don't forget you are now competing with lots of people who were not previously aware of that item...some you know, many you don't. If you want it, it might be an idea to buy it very quickly before someone else jumps in. If you don't like it, it can go back on eBay and needn't cost you very much a...

On the brink of LBA!!!
£55 is above my "impulse buy" limit. There is a Cosina one but it looks battered. As John says, it can alway s go back on Ebay if I don't like it! Off to spend to money :lol:

On the brink of LBA!!!
You can always say to your wife that you buy lenses for charity reasons. You just helped another photographer suffering from severe form of LBA to raise some money for his much needed cure! Surely she will understand. I like that idea! :lol: Unfortunately Alan's idea won't work...I had to send ...

looking for photos taken at 10mm and 17mm please
First of all - DinneenP - Pentax, this sounds a bit familiar to me.... can it be, we know each other ;-) Have to say - there is a massive difference between 10 and 17 mm and I would even say that there is a significant difference between 10 and 8mm. I had a 10-17mm fishey but gave it back, as somet...

Macro: Extension tubes/bellows/closeup lens
If the extension tubes support the electrical connections lighting can be done easily & reasonably well with TTL flash. Either off camera (arms reach away typically) or bounced via a suitable placed white A4 card. With the option to check trial shots, working out manual settings shouldn't be too ar...
