Hi all, I’m looking to get a couple of circular polarisers for my rfs 18-150 and rf 100-400. I don’t think I need (or can afford) anything special, but just wanted to check people’s opinions on these. https://amzn.eu/d/cjuYP08

TIA,
Dom
 
I bought one of those in 67mm and have no issues with it at all (for my Tamron SP 85mm F/1.8 Di VC USD).

Crap filter + good lens = crap image.

If you're going to use a filter it has to be a good one.

They can be picked up used on Evil Bay at more bearable prices:

Not sure it's a great advice suggesting 105mm filter for a compact budget mega zoom. Not practical to say the least

Also had horrible experience with plastic fantastic filters from this same company
 
Ive had a few of those K&F filters and never seen any issues with image quality.

who decides if a filter is crap - just because its a stupid amount of money doesnt mean its good.

K&N concept filters are well though of by those that use them

I wasn't suggesting that - I was just showing the price difference when buying second-hand compared with new. This is the polariser that I have, so it was the first that came to mind.

This is the price of a new one:

Good point, some people are happy with crap and don't know the difference.
 
I've got a few K&F bits; polariser, ND filter & black mist filter. Not had any problems with the images from them, and would happily buy more.

If I was looking for a second hand one on eBay instead what brands would you recommend? I’ve heard of Lee (but none available) and Hoya, are they good?

I think one of my filters is Hoya. Certainly haven’t heard any horror stories about them.

I’ve got quite a few filters now, and it’s a real mix of makes from cheap (including K&F, but also stuff I’d never heard of before like Pig Iron, which I found on eBay), up to more expensive brands like Urth and Manfrotto; and I don’t notice any difference in quality, whatever I’m using.

Is this a couple of different filters or one for each lens? Sorry if I've missed something.

If you are looking for a filter for each lens an alternative could be one filter to fit the widest diameter front filter thread and a step up ring for the smaller diameter lens as step up rings are cheap and filters can be more expensive.

Soz if I've got this and your needs wrong :D
 
No that would work. I just need a circular polariser for a 55 and 67mm lens
 
There was a test a while ago where filters were tested for quality, it was found then that for the most part you need to stack 3 or 4 filters before the quality is badly affected. They also found little difference between the cheap and expensive filters. The biggest difference was ND filters being more neutral coulur in the expensive ones.
One of the camera magazines did it.
I've used 2 ND filters a few times (cheap ebay) and I've not seen any problems with it affecting quality.
 
So there’s not a lot of difference between getting cheapish K&F circular polariser and say a Hoya second hand from eBay?

I'd follow the advice of @woof woof and get a step up ring. One filter would work on both lenses then. Should allow a slightly higher budget for one filter as step up rings aren't too expensive.

It’s really good advice. My only concern is that as I’m going on safari, I’ll want to be quick with any changes, and having to change the lens and a filter might be too much of a faff if I see a lion heading right for us!
 
Get a cheap one and get a more expensive one then you can compare the two.
 
If you do ever buy a step-up ring, I recommend a brass one - others seem to 'stick'.
 
a second here for Hoya HD. Vs the standard Hoya they let a lot more light transmit to the sensor.

I don't know if that means that the polarization effect is less - never had a problem myself.

Just in case you weren't aware, this company does reasonably price filters, rings and so on - https://www.srb-photographic.co.uk/

However, full disclosure, the last circular polariser I bought for my RF100-400 didn't work out for me trying to accentuate sea and sky resulted in poor focus. I strongly suspect it is user error or just a bad instance of the filter but just so you know.

I appreciate there is a sense of "why the hell is he recommending the place then?" but they do stock a plethora of useful adaptors etc.

All the best,
 
I bought some K&F UV filters. They work okay - but do seem to collect and hold a lot of dust! No sooner have I puffed or wiped the dust off, than it's back - almost as if it's full of sttaic all the time.
 
Both Nisi and Gobe make mid-range filters at a good price.

CPL's are primarily used to reduce reflections, and increase saturation in the sky - and need to be rotated to get the effect you want - usually this is when taking landscape, when you have plenty of time to set up the shot, rather than wildlife or safari.
