Lens hoods – are they really usuful?

Hi Pentaxian friends.

Most, if not all, lenses are supplied with a lens hood these days. A regular tube hood is commonly supplied with telephotos and petal type hoods are supplied with wide-angle lenses and zoom lenses. The petal types are built as such because the sensors are rectangular, and if you noticed, the hood extension is longer on the vertical portion of the sensor. It stands for a good reason as when using a wide-angle lens, the tip of the hood would be part of your picture if it was as long on the horizontal axis.

Since I use rotating filters such as the Circular Polarizers and split Neutral Density filters, I need a quick way to rotate the filters. Although Pentax has a removable door on the bottom, where you can logically rotate your filters with your thumb, I found that it doesn’t work all that well. Because you apply the pressure with your thumb, this has a tendency of putting more stress on one side of the filter and the rotation becomes much harder. It would be great if hoods would rotate as well, but that wouldn’t work with petal type hoods.

It is for that reason that I rarely install the supplied hoods on my lenses. First, they increase the length of the lens and become a hazard. Secondly, I can use my hand to block the sun rays just as good as a lens hood can.

You can also get a collapsible rubber hood with filter threads, install it like a filter, or over the filter you are using. That way, the filter and the hood will turn together.

P.S. I found a website that actually lets you download a PDF file containing some of your favorite Pentax Lens hood. You just cut it out, fold it and slide it on your lens. I would paint it flat black myself. Check it out.

I also found this ingenious person that made a good looking hood himself.


Thank you for reading,

Wide Angle Lens Converter 52mm

Looking for a wide angle lens for your Pentax or Nikon DSLR?

A perfect way to transform your kit lens into wide angle lens for a quarter of the price is to get the 0.7x wide angle converter. It has 5 star reviews on Amazon UK, and for £70 it’s a real bargain. Those who bought it feel really satisfied with it claiming that the quality of photos is surprisingly high. 5 Stars

Digital King DSW Pro 0.7x Wide Angle Lens Nikon/Pentax 52mm

Please, read what the buyers thought:

I have always needed a slightly wider angle than my Pentax K10d’s 18-55mm lens was able to provide, but I was not willing to pay for a Pentax wide angle lens, which costs as much as the camera itself. So when I saw this adaptor, I went for it, and I’m pleased I did; it works very well. There is no vignetting at the corners at the widest angle, which is often a problem with such adaptors, and there is no discernible reduction in photo quality. Of course you do get ‘tombstoning’ when you take photos of buildings with the camera tilted up at an angle, but this is a normal feature of most wide-angle lens. The adaptor lens is 80mm in diameter and 15mm in thickness, as such it is larger than the barrel of the 18-55 lens, but it does not look ridiculous when attached. The adaptor lens comes with its own pouch, proper front lens cap and a rear push-on cap. Perhaps the only ‘con’ of this adaptor is that it’s attached to the camera via the 52mm filter thread and care needs to be taken when attaching it. If you intend to be constantly removing and re-attaching this lens, it could get a bit tiresome; this lens adaptor cannot really be described as ‘quickly detachable’. I myself intend to leave it on most of the time. One ‘pro’ of this adaptor-lens is that it doesn’t take up a lot of room. It will easily fit in a coat pocket or camera bag. I would not hesitate to recommend this adaptor-lens to the photographer on a budget who needs a wider angle photo, but doesn’t want to pay out hundred’s for a wide angle zoom lens.

Or another one:

Like a lot of keen using a DSLR with standard 18-55 mm (kit) lens I began to look at other (in this case wide angle) lenses and was immediately confronted with the high cost of wide angle zooms. Again like many people I was a little taken aback at the cost of the Sigma 10-20 zoom at over £300 even on Amazon.

After a lot of research on the web I came across the Digital King wide angle lens – .7X which is made in Japan and is designed specifically to work with a 18-55 kit lens. It just screws on the front like a filter.

Took the plunge and bought it through Amazon UK although it was supplied by RK Photographic. It arrived 2 days later inside a nifty pouch with draw string and protected by front and back good quality lens caps. Total cost less than £70.00 p&p free. Free 5 year guarantee.

I have to say when I took it out of the box it looked beautiful. Obviously larger in depth and diameter but still light to use. On maximum wide angle of the kit lens (18mm) it becomes a 12.6 approx wide
angle lens. The quality of image using my Nikon D40 is simply superb and I’m sure would easily meet the standards for keen amateurs. It gives a pleasing natural wide angle “distortion” when used closely to objects although less than a fish-eye would but it is still quite dramatic.

It was interesting because when I looked more closely at reviews of this lens in other web forums I was struck by how the most vehemently against this type of lens clearly had not even used one let alone owned one. This is what convinced me to buy the Digital King lens. No-one who owned one had criticized it. It seems to be a result of a certain sort of snobbery: you will only get quality by paying through the nose for it. This in my experience with this lens is complete nonsense.

Instead of paying £310 I paid less than £70.00 for a very useful wide angle – I admit that it doesn’t have the flexibility of a wide angle zoom but with a saving of £240 I’m willing to put up with that and maybe buy that Blu-ray player from Sony that I keep hankering after?

And one more:

After using two slr’s (a Canon film slr and an Olympus dslr) that employed dedicated multi-element wide-angle and telephoto converters and having been pleased with the results, I thought this converter worth trying. Happily my initial experience actually confirms all of its maker’s claims. This attachment has a single glass element specially designed to match a 18-55mm dslr kit lens at its widest setting. My converter is 52mm dia.(for a Pentax K100d) but I believe a 58mm dia. version is also available.

The performance on my camera is excellent. Perhaps not only due to careful design and manufacture but as experience suggests, the less glass added to the front of a good camera lens the better. Being lightweight and compact the convertor slips conveniently into the front pocket of my zoomster camera bag; accessories are no use unless to hand. Other plus points; there’s nothing to go wrong, all camera functions are retained. Also the chance of dust entering the camera is eliminated by using a supplementary lens rather than changing lenses.

Reasonable care is needed screwing it to the host filter ring but my converter spins on and off freely with its milled edge, black crackle barrel providing a secure finger grip. The lens appears to be coated to minimise reflections (its housing is marked MC) and the metal barrel although shallow seems to offer some shading. Toda-Seiko Ltd (Japan) have been making conversion lenses for around 20 years and for all kinds of optical equipment, something I found reassuring.

Not everyone can justify or afford an expensive prime or zoom wide-angle lens but they can enjoy the added fun and interest of creating more dynamic photos. with this converter. My example cost somewhat less than the current widely advertised UK price so do shop around.

Give yourself a bit a luxury for a tiny price. If you always thought about getting a wide angle lens but could not afford, now you can! Click the link below now:
