What filter for 16-80mm CZ??

[synapseman]

I've tried B+W MRC Haze and Hoya Pro1 Digital. Both cause vignetting at the 16mm end. The Hoya Pro 1 is *slightly* better in this regard, but it's still obvious enough to cause annoyance.

Anyone manage to get a filter that doesn't give vignetting problems @ 16mm?

What, where and how much? Thanks!

Hi,

I am using a B+W F-Pro 62 KR-1.5 Skylight 1.1x MRC from CP about S$80/-. Also used a Hoya HMC Skylight 1B before from MS colour at about S$40/-. Never have any vignetting problem at the 16mm end. Always use at the 16mm end.

CZ is releasing it's own filters for this.

Wah! Another money-milking venture from SONY...

Any slimline filter from any of the major brands should work I guess... must specify for ultra wide angle lenses...

Sony filters? What's the price gonna be like? $120?

Does CP stock Heliopan? I hear they're about as thin as you can get.

woah. cheap cheap!! remember, it's a CZ. so even a 1k lens cap is cheap in CZ terms.

and i use the hoya pro1 for mine........... doesn't seem to have much vignetting leh.

Hi people,

I have given up the search for an ultra-thin 62mm filter for this lens. Wouldn't have been cheap. And even if I do find it, there's not guarantee that it would not cause extra vignetting.

Some people have had success in mounting 62mm filters w/o vignetting? When I tried on my copy, it isn't just light fall-off, I can actually the filter frame on the top corners of the image! Differing manufacturing tolerances perhaps?

Sony's own filter for this lens, I also couldn't get any info on when it's coming. Alpha showroom @ Cathay told me of some "QC problems", so "shipment will be delayed until dunno when"...

So my solution: 72mm Hoya Pro1 Digital mounted on a 62-72mm step up ring. No problems. But major disadvantage is that I cannot use the lens hood any more.

What about slim versions of the filters? They usually don't come with threads to stack another filter but they have a thinner ring.

Get a generic hood for 72mm...

Actually the ProDigital filters from Hoya should fit... they are ultra-thin... there should not be a problem finding filters for this lens cos there are quite a few users around and I have not seen any complaints... do bring the lens and body down to Cathay and try out their high end ultra-thin filters from either Hoya or B+W. It's going to cost you though, $100+.

I've tried going to CP and MS Color. The thinnest they have is the Hoya Pro1 Digital.

Generic hood will screw onto the front of the filter, yes? Might need to try that out also.

I'm a bit surprised that people can mount the 62mm filters straight on to their CZ1680 without any problems. When I did, even the SHMC Pro1 filters were no good. Could defnitely see the inner edge of the filter. In fact, I tried to mount a 67mm filter via 62-67mm step-up ring - still could see obvious filter shadow! It disappears around the 17/18mm mark, but I feel I shouldn't need to compromise in this regard.

The B+W UV Haze MRC Slim filter has a 3mm ring which is as thin as the Hoya Pro 1 Digital. And I can't find anything that has a thinner ring. Can't help you with the filter.

Just to check, does it vignette even without filter?

[UY79]

Ok, according to this the vignetting is quite sever at 16mm at f/3.5-4.5, up to 1.41EV. But they don't have a sample at 16mm to examine or compare. Maybe that's the reason why?

Yes, it does vignette even w/o filter. The light fall-off is quite apparent, but still acceptable. However, when the abovementioned filters are mounted on my lens, it becomes totally un-acceptable because it's not even a case of light fall-off anymore; the filter frame actually intrudes into the pic!

A little bit disappointing lah, honestly. For such a premium grade lens, I consider this as a fundamental design flaw. Also have the Sigma 17-70mm, and I think Sigma has this already taken into consideration in the design.

No problems with the Sony CZ filter.

I doubt it. That filter is 5.5mm thick.

[Trigger Happy]

the hoya pro1 filter shd not cause vignetting at 16mm. did you screw it on tight?

[dr34mc4st3r]

minor vignetting shouldn't be too concerned about it. can be fixed in photoshop or lightroom.

sony/cz simply designed this lens filter thread size way too tight. would be much better if its a 67mm or 72mm front filter thread.

[synapseman]

From what I read in dyxum.com reviews, it seems that it is impossible to find filters to mount onto the front of the lens without causing additional vignetting (at 16mm).

However, I am somewhat surprised to hear that some users here have managed to use 3mm thick filter frames (Like Hoya Pro1D) without any problems. So I have to conclude that there could be differing manufacturing tolerances, or even slight modification of design?

And yes, I do know how to screw in a filter!

The way the VF-62MPAM is designed, the internal section is angled away; this prevents vignetting. This makes it a pain to use the lens cap though.
