Irix 11mm Firefly
I'd seen the 15mm has a detachable hood and can take 95mm dia. filters. But I've just been watching another YouTube video and the front element of the 11mm looks really bulbous, with no chance of fitting a filter

Irix 11mm Firefly
Just an update. I've ended up with the Samyang 14mm f2.8 following a recommendation from a landscaping friend. I mentioned, I'd scraped together a filter set to try some long exposures, well that was based on the Lee 100 system. According to Lee the Irix 15mm lenses are not compatible with that sys...

DFA 24-70 - is it worth it?
I currently use the DFA 28-105mm with the K1, but am wondering whether it would be worth getting the DFA 24-70 mm f2.8 for landscapes? This format seems to be the go-to lens for Nikon and Canon landscape photographers, and another reason is that I have the Lee filters SW150 filter system for the DFA...

Advice wanted re a graduated ND grad - screw fit, not gel or similar!
I have an ND grad with a fairly "hard" dividing line for some of the lenses - but thinking about a more progressive one for the 10-20 & 17-70 Sigmas. Filter thread sizes would around 62-72mm, and I would prefer not to spend more than about £50-60. Not interested in gel/similar or plastic (like ...

What do you mean, screw in? Grad filters are all square and slide into a holder, that's the only way to adjust them. Take a look at Cokin Nuances, they are glass in your price range, and get a decent filter holder to protect them! I have a holder with credit card-like pockets but the filters stick ...

Thanks but no-way will I be getting any of square filter holder systems - too much "trouble", and not enough potential use for what I would want. And, actually, you are incorrect about there being no screw-in graduated ND filters - for example , although that is not the size I need.

. Trying to fit anything like these on the 10-20mm would seem to me to be a non starter though. Might be OK with the 17-70 if anyone makes/made them in the correct size (but doubt they do.) Given the dynamic range of the sensors now, do you really feel they are necessary? Just do the grad in...

Advice wanted re a graduated ND grad - screw fit, not gel or similar!
Screw on Grads have always seemed a daft idea to me. I want to compose my image to fit the frame not have to it it to the grad. Square type filters can easily be held in front of the lens for normal range exposures - without bothering with the filter mounting kit. But I have to say software gener...

I am corrected, never seen round grad filters! Obvious problem is you cannot control where the change comes, always halfway down so your horizon has to be across the middle too. I'm with jeallen01 cannot be bothered with too much time in Lightroom but once you have screwed on a square filter mount i...

Your going to stuggle I think, to buy new, in glass for £50 - £60. (Hope i'm wrong). Most cost nearly as much as the lens. The two lens filter sizes are different so Im assuming your going for a 77mm filter for the 10-20 and a 72-77 stepping ring for the 17-70. Many of the cheaper filters leave a...

Macro 100mm WR overexposing
Curiously, Auto setting exposes perfectly. Never used it before but you can set the ISO and in the menu are some priority options, I selected the one for sharpest images (it uses the lens ID for this); could have been depth of field or shutter speed. Here are a couple of cropped images from today wi...

What lens Are We Waiting For?
[quote:3496ace15f="DrOrloff"]What mock-up primes were those? Back in February Ricoh exhibited pre-production models of the forthcoming 50mm and 85mm lenses, but it’s all gone very quiet on the lens front since. Its all about THETA now....[/quote] Can't disagree with that, unfortunately. I can'...

Wide angle
Excellent lens for the money. I've had both versions and preferred the 4-5.6 version as it's a bit more manageable in terms of size. The filter size at 82mm for the f/3.5 is a bit of a turnoff really, so the 4-5.6 version is just perfect.

Wide angle
Jumping in late! I owned the fixed f3.5 for a while, bought it new and it was a cracker of a lens! The fixed f3.5 has an 82mm filter thread and the variable aperture was 72mm from memory. If I was to buy another I'd buy the cheaper variable aperture as I never used it under f8!

Thoughts on non-HSM non-OS Sigma 70-200
I've been pleasantly surprised by the 300 APO wide open, but I've heard a few reservations expressed about sharpness at maximum zoom and aperture on lenses such as the Bigma and 120-400 - I'd expect some compromise to image quality given the focal lengths and ranges of those larger lenses, but wasn'...

Thoughts on non-HSM non-OS Sigma 70-200
Weather's put a bit of a dampener (well, more of a chiller) on my outings so I've not yet used the lens in anger, but a quick tests shows the AF is a lot snappier than my 300mm and the sharpness appears good at most points. As an aside, it has the exact same filter size and tripod mount as my 3...

Vignetting with an ND filter
Here are a couple of photos I took earlier, both with the DFA 15-30mm at 15mm and a 3-stop soft grad filter. For the second I added a Lee 10-stop big stopper to extend exposure to 30 secs; I was quite pleased with the effect but there is serious vignetting which I guess is due to the light path at t...

Vignetting with an ND filter
Did you use the Lee wide-angle adapter, which keeps the holder closer to the front element ? I don't have much experience yet as i am a new user of the Lee system, but I would expect vignetting at 15mm. Have a look on the Lee website where joe cornish gives some tips in a video and I think he men...
