Hoya 28Mm F2 8

In some clever engineering, Fuji built the aperture blades right into a round capsule that may be taken off the lens as a unit. On the 50mm, this was stuck in the barrel by lubricant, therefore i mistakenly tore the lens down further to extract it. This is when I discovered that I could have broken it loose earlier in the process with handful of naptha round the sides. I spent hours focusing on it, but I could never get the thing back together properly from then on. EBay is full of lenses with stuck open aperture blades, so that it could open up some sort of cheap lens side project. A shame, since the lens was otherwise in excellent condition, with a pleasing metal build, smooth focusing and aperture rings, compact size and minimum focus of just beyond 0.27m.

The higher the rating, the closer your focus can be etc. On a minor note; the +4 lens does a good job at starting fires utilizing the sun! That’s another reason to carry one with you on your photo outings in the event you get lost. The Hoya 28mm F2.8 is a great lens – when in good condition. Like all wideangles, the retrofocus rear element lens is both small and is quite close to the film or sensor.
The tiny lenses reviewed here are a sensible way to save money, weight, and space on photo expeditions rather than packing an expensive macro lens, though they really won’t replace a good macro lens. This review will cover the Hoya 3 piece close-up set with diopter ratings of +1, +2, +4. The lens used is definitely the Minolta 35-70mm F/4 generally, and a few comparison shots at the end with the Sony 28mm F/2.8, each mounted on the Sony A700 DSLR.

• The IQ rating of an old lens depends upon the clarity of the optics.
• Fair-to-good sharpness range from centre-to-edge, too.
• It’s not as effective as a Takumar or Pentax 28mm or 35mm, but it’s good-ish.

I feel that landscape photography should take the time and the fact that everything is fully manual with this particular lens, just increases this experience. You have to think through all the settings and this extends into your ideas about
Then i found the lever that moves the aperture blades open and shut, deeper in the bowels of the lens, and eased it tentatively with a screwdriver. So I gently dabbed a cotton bud soaked in lighter fluid round the aperture blades, and gave it a chance to soak in just a little. Most modern cameras will shoot video to one degree or another, but these are the ones we’d look at in the event that you intend to shoot some video alongside your photos. We’ve chosen cameras that can take great photos and make it easy to get great looking video, instead of being the people you’d choose as a committed videographer.

• Also, like a magnifying glass, you can’t focus to infinity, or much farther than close focus on your lens.
• Realistically speaking, it will be hard to use the +4, +2 in the field.
• The long depth of field this lens renders, it is like you usually do not even have to focus your camera!

Dust, haze and debris have a greater magnified effect than with telephotos which have much bigger rear lens elements. Plus wideangles get to have significantly more sun in the picture – increasing the risk of flare. If I were searching for one lens for just about any of my Nikon’s I wouldn’t hesitate to rate that one right up there. Although its a manual focus lens but just what a lens! Quality you don’t find in the more modern design plastic lenses.
The set posseses an instruction manual and nice travel case. There is not much else to describe about the lens set or filters because they are sometimes called. They sell on eBay for about $20-$50 depending on size, mine are 49mm. I never really had much luck, and wrote a few off, struggling to put them back together, though their pocket money price, stiff focus and stuck aperture blades meant I didn’t lose any sleep on the loss.

The easist solution to look for haze, fungus and debris would be to shine a torchlight from behind. To photograph it I use the light of a laptop screen and a small sensor pocket camera – use these due to incredible close-focus ability. Now Tokinas in their Hoya badging are well made and the structure of the lens is very like the Pentax A 50mm lens – so it is simple enough to unscrew the front and obtain the lens elements out for a clean. In this case it also needed some of the lens elements to get a soak in 100% ethanol and detergent to clear the fungus.
