DFA100 WR good or not?
Why does it work better with the macro flash? With the FA lens, you screw a ring on to the front element where a filter would go, so that the ring flash has something to attach to, so when you are focussing the ring flash moves in and out at the same time. It feels like a strain on autofocus! Wit...

Pentax-A 28-80 3.5-4.5 macro.
I have just been given one of these lenses but have a slight problem. It looked like it had a badly scratched filter on it, but when I unscrewed the filter (in fact it popped out, it's held in place by 2 metal rings) I found out it was not a filter at all but appears to be the front element, about 3...

pentax 35-105mmA lens Hood
According to http://kmp.bdimitrov.de/lenses/zooms/medium/A35-105f3.5.html you need a Pentax RH-B70 hood. Or any to fit a 67mm Filter thread. What you will have to be careful about is, a hood that works at 105mm may cause a problem at 35mm. conversely one for 35mm may be no good at 105mm

I generally leave a uv filter on every lens i have all the time to protect the front glass, is this a good thing or a bad thing? UV should be used outside i know but what about indoor photography for example in a studio environment, should it stay on or off, will it make a diffence to image qual...

Well not should but generally would be is what i meant as uv comes from the sun and a uv filter used outside would help block uv maybe saying should be used outside wasn't meant in the way i made it sound was talking hypethetically, point is that i'm asking is......i'll rephase it......i'm led to...

I have seen somewhere? an advert for a lens protection filter, if I remember its plain glass, so would this be a better type of lens protection to use :?: I also use a UV filter (must get one for my 55-300) as protection of the front glass on all my lenses

Glover this is indeed a can of worms like Mike says, it has been discuss quite some times now. UV filter will have limited effect on digital because there is an UV filter in front of the sensor, so basically you've a piece of glass in front of your lens making flare more of a problem and costing ...

Well I for one will always use a protective daylight or uv filter. A good quality glass one - never plastic:shock: As for insurance, well some lenses just cannot be replaced!

Strikes me there's two schools of thought here Filter on at all times Filter on when it's only needed . You pays your money [ literally :mrgreen: ] and you makes your choice. I've made mine having seen someone in our class drop his camera on the floor and err , well let's just say it w...

Very interesting topic, I watched Stefan's hammer and lens video and winced on every hit, worst horror movie I have ever seen:D. Re lenses breaking, I once foolishly left my old Pentax MZ50 with kit lens & UV filter in its camera bag, on the washing machine. The washing machine was turned on and the...

after reading everyones comments i decided to do a little test, (not much as i'm at work) i took the uv filter off my 50mm 1.7 to see if there were any diffences, a little sharper i think without seeing them on the pc, but the biggest thing was the focusing, i've always found it hard work getting th...

Kenko make a lens protector,according to the company, the MC Protector will not "affect the colour balance of the scene being photographed". A 67mm filter will set you back between £25-30. Regards Chris

My Pentax 600 F4 and 300 F2.8 both come with lens protection filters as standard. I believe they are part of the lens group and removing them would affect lens performance. However, in the event of damage, the front element is protected and it is a protection filter only (maybe) that would have to...

I've made mine having seen someone in our class drop his camera on the floor and err , well let's just say it was most unfortunate and there was no filter on . I'm a bit sceptical about what you are trying to say, I'm not saying it isn't true what happened but that a "thin" filter would have make a ...

Technoidiot the story you were telling about the lens falling read to me as a reason why you use an UV filter. It just so happen that Technoblurb has a story of his lens falling with an UV filter and it didn't do him any good. That's why I'm trying to say that an UV filter will not protect your le...

Yes I agree but that's not my point. It's seems that you're making the assumption with your story that the lens would have survived the fall if it had an UV filter. I'm just saying that I'm very sceptical that an UV filter would have make a difference when you let a lens fall. I could have rea...

With the 'stress' this post is raising it could be better to consider it closed, every one seems to 'do their own thing' I don't see why. IMO there are too many knee-jerk calls (largely not acted upon by the mods, I'm glad to say) to close threads these days as soon as a discussion becomes less tha...
