10 stop ND filter
10 stops is usually enough. Just remember the 30 rule, 1/30s exposure equates to a 30s with ND110 exposure. Often ND110s are a little off though, ie mine is actually closer to 11. Multi exposure is all well and good but pants for greasy clouds really. Because you see stuttering, so instead of smo...

Cosina 100mm f3.5 manual focus adaptor?
Hi, this lens apparently originally came with an adaptor that screwed into the filter thread to change the macro from 1:2 to 1:1 and was matched to the lens. I could try using an extension tube but would rather try and source the adaptor also I do not know what length extension tube would make it 1:...

Cosina 100mm f3.5 manual focus adaptor?
I've being doing a bit of internet pottering recently and have bought a couple of achromatic macro/close up lenses to stick on "standard" non-macro lenses. Also I was looking at a similar 1:2 lens and read (but can't find the reference yet) that the 1:1 adapter is a +3 dioptre lens. However tr...

Cosina 100mm f3.5 manual focus adaptor?
Oh yes remembered this rough comp, the 58mm is not a macro lens but https://www.pentaxuser.com/forum/topic/vivitar-55mm--nokton-58mm--macro-filter--sigma-105mm--rough-comparison-29690 I'll do this again more cleanly with the +5 Marumi when I have a bit of time.

tamron sp 300 f5,6 AD 2
From adaptall-2.org: Tamron SP 300mm F/5.6 Model 54B: A very good fixed focal length lens with excellent macro capabilities. Lens continuously focuses from infinity to 1:3.3 macro and features a built-in lens hood. Most importantly, this lens features a special "spherical aberration compensator gro...

18-135 first impressions (on the K-5)
This thread is more about the lens than the photography, since one or two have asked about that, so I've put this here rather than in Your Photos. This from yesterday - DNG, 24 mm, F10, 1/200s at ISO 200 It's almost the whole frame, with just a little featureless sky and foreground croppe...

18-135 first impressions (on the K-5)
Ok, here are a couple more. Again, nothing remarkable about the pictures, just a couple of other focal lengths. All the following have been sharpened a little using the high pass filter overlay technique, starting with a DNG. First up, 70mm and F8: A couple of 100% crops from it... fi...

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...

Have you tried using rubber gloves for more grip?

Rubber gloves is an excellent idea - works on jamjars too! there are also lens filter wrenches available for stubborn filters - they are only a couple of quid I think. Worth a look on ebay or a camera accessory website I reckon if the rubber gloves don't work. EDIT: This is the sort of thing...

Thanks. The long barrel on this lens means that there is a lot to hold but I felt unsure about how much punishment it would take. Will look for removal tool and gloves. :oops: Regards Chris

Soften up some Blu-Tak by leaving it stuck to the side of a kettle that's recently boiled or hold near to a fire/radiator. Roll it into lengths about 5mm diam. Stick it on the edge of the filter rim, so the rim is fully covered. Place lens perpedicular to a Formica topped or glass table....

Place a rubber mat on a table. Push the lens with the stuck filter down onto the rubber mat. Twist the lens anti-clockwise. You can buy jar top removers from kitchen-ware shops. I have also seen these in Pound Stores. These are a plastic handle with a rubber belt.

One thing to watch out for is gripping the filter too hard on opposite sides - this distorts the rim and locks it more firmly in place.

If it's been on for 18 months, any special reason why you want to take it off now? Might just be best to leave it as is. :D

The bottom of a mouse mat is often an ideal grippy surface to use too - push the filter down onto the mat and unscrew it that way. Just make sure that you grip a part of the lens that's directly connected to the filter ring so that you don't strip any helicoids or internal gearing - that goes for al...
