77mm filter on an 18-135

Does anyone know if you can fit a 77mm filter/step up ring inside the lens hood of the da 18-135. Is there room to mount it and turn it (cpol) or does the hood need to be removed to fit it and use it

No there is not. The hood has a diameter of 62mm.

Yeah, it would definitely have to be removed. Like Adam said, the filter size is 62mm and there is not much room past that.

Thanks Adam, I guess I should have been clearer, I know the 18-135 takes a 62 mm filter but the inside diameter of the hood is greater than that (i.e., there is a gap between the inside of the hood and the outside of the 62mm filter when mounted. By crude measuring (I dont have a caliper that fits) it looks like a 77mm (with a 62-77 step up ring) might fit (but only just) but I dont know if it could be screwed in properly and manipulated as I dont have one to try.

I'd like to get some decent 77mm filters to cover a range of lenses that I have and I know they can be mounted to the 18-135, its just a question of weather or not i can use the hood at the same time. I realize I wont be able to mount or remove the hood with an oversized filter in place.

why don't you just measure it?

I can't measure it accurately as I dont have a decent way to measure the inside diameter of the hood, the only caliper I have wont reach. even if I did, the hood flares from the mount outwards (so the further from the front element the greater the diameter and without knowing exactly where the filter would sit (depending on the filter and step up ring distance from front element will vary) I'm not sure where too measure.

I appreciate the input, not trying to be difficult but it looks close and I dont have what I need on hand to try it. I think your probably right in that it will be too tight, not a big deal I'll just bring the lens next time I'm at a shop.

Cheers folks.

Took a measure of mine using a ruler, so not accurate within 0.1mm.... but I am getting 78mm at the exterior edge of the pedals of the hood, and about 75-76 on the interior edges. The hood does have a taper to it. So, I would believe that with a step ring and a filter put in there, which is adding bulk and not really moving the lens further out, it won't fit. But I don't have the ring nor the filters to try.

I've got an 18-135 and a 77mm CPL.

No it doesnt fit.

The the frame on the filter is 78-79mm OD, the inner edge of the hood at the very end is about 76-77mm ID so you have to bend out the petals of the hood to even insert it a few mm into the hood ( huge gaps of daylight coming in the sides and the filter is impossible to turn.)

2 choices are 62-77mm step ring and NO HOOD or cough up the $$ for a 62mm filter just for this lens.

Thanks Steve, I'll do the step ring and no hood for now and see how it goes before doubling up on filters.

Cheers.
