Yesterday I was taking photos with the Radionar on 5D and happened to take a photo of the same target both with and without a lens shade. The difference between these two shots was quite dramatic so today I decided to take a series of parallel test shots with and without the lens shade. The day was overcast, and I had to use rather silly exposure times for a 105mm hand-held lens, 1/60 s - 1/20 s, so all the shots aren't very sharp - especially as the front-cell of the lens is set to soft focus. I didn't change any settings between the shots of a pair, but the focus may have drifted a little bit when I put the shade on the lens. There may also be some slight vignetting on some of the shots taken with the lens shade, which was sometimes a little bit skewed. As you can see from the attached example pairs, the effect is quite appreciable.

Same here, I have a hood for every lens I have except for my Sigma 14mm f3.5, which has a sort of built in petal hood.
Recently I bought a Tamron SP 17mm f3.5 which did'nt come with a hood and unlike my Tokina RMC version it does'nt even have a front filter thread, so I cant fit it with the 67mm rubber hood or filters that I use on my Tokina . I am not used to using naked lenses so I'm desperate to find a hood to fit it, even if I have to make one. |

Very important of course. But in a lot of older magazines the revolutionary change was the single coated over the not coating at all. The difference between the single coated and the not coating lens is more dramatical than the difference between the multicoated and the single coated. Of course the limit of my affirmation are the lens from one to six or seven elements. In wide angle and zooms, the MC is by far the best improvement.

@ Vilva
Thanks for this test.
I do a lot of shoots now with my more and more beloved triplet lens Trioplan 2,9/50 and the lack of CAs and the sharpness at f16 is great. Beautiful color rendition.
... and as I see now, I need a hood.
@estudleon:
Thanks Rino for the Hood-site.
It is a real Robin Hood site (hoods for the poor )

Exactly, without a hood light enters the lens - and will be reflected and scattered even on the black surfaces of the lens barrel! This is ~ the same for both uncoated, single coated and multi coated lenses. With no coating (or single coating), more additional light is reflected on the lens surfaces than with MC.
I have a Porst 135 / 1.8 MC - with a huge scratch on the front lens. Without a hood that lens is crap, with large round hood (from a Zeiss 180/2.8 for Pentacon Six adaptet) the lens ist usable, with low image contrast. _________________ Camera modification, repair and DIY - some links to look through: http://www.4photos.de/camera-diy/index-en.html

Yes!!! Thank you!

trimming of the image circle drawn by the lens onto the film or sensor is done by a mask over the rear of the lens.
attempting to trim using a hood reduces lens aperture. masking the front of the lens also shapes bokeh; for heart-shaped bokeh use mask with a heart shaped opening. _________________ ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮ like attracts like! ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮

I've experienced similar effects while using the Takumar 135mm f/2.5 ...and I got a similar low-contrast effect even with my "new" Pentax-M 28mm f/3.5.
Both have a lens hood: the 135mm has it's built-in hood but has no SMC; the 28mm has SMC and I use it with a metal lens hood.
I fear asking myself why I have experienced these effects with the 28mm... is the SMC gone??? ...or, wait, could it be cause by the UV filter in front of the lens?
Is there some place in Europe (or even better, in Italy) where I can buy screw-in metal lens hoods? At the moment I bought mine in the USA from a really nice vendor... but I always fear some fee on the package.

What a great comparison! I only have a few lenses with hoods, but then again I only have few lenses. I have found differences, even using a baseball cap or my hand to shade the lens. It looks like I could do better using a fitted lens shade, to completely encircle the lens. _________________

It's all about three things: coating, coating and coating. |
And besides the coat, hood, hood and hood. Look at any picture of a film and will always be a black screen shading the lens.
This test can be with any lens and will be greater or lesser effects but there will always be a difference.
It is essential, I promise to seek a review of Takumar, their coatings. It showed that percentage more light, let in a Takumar SMC in respect of Super Takumar, I think a 3% + and the hood keeps a mirror effect on the surface.

Well, I'm a big fan of hoods also, but I don't have them for all my lenses. So, like Laurence, I use my hand in those cases. I have found that I can usually do a good job of controlling ghosting and especially optical reflections (you know, the off-axis iris- or lens-shaped images you get when a strong light source intrudes?) just by moving my left hand about until I've found the best spot to eliminate it. And if my hand is too narrow (usually isn't), holding something bigger up there -- maybe a folded newspaper or a piece of cardboard or whatever -- will usually do the job.
Not as cool looking as a hood and not as convenient, but it works well. _________________ Michael

The other reason for hoods is protection, most especially for SLR lenses.
All sorts of nasty objects can be kept away from the glass with a good sturdy hood, particularly my fingers. It also helps when a lens/camera is dropped.
Finding good hoods for the old folders can be a problem. I have a couple of nice ones, both spring type and press-on, but I have been collecting these things from lots for a while.
Unfortunately spring and press-on hoods are not very secure, nor can a hood be kept on a folded-up camera. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |
