Pancake/Cookie lens

It’s a colloquial term for a flat thin lens assembly that started to emerge from the 60s through to the 80’s, commonly seen in compact SLR cameras of the time. This then developed into a body cap lens, an extreme type of pancake lens that is designed to both protect the camera internals as a body cap normally would, yet still allow the user to take photos. These lenses are manual focus only and generally have no more than a couple of optical lens elements, no image correcting elements, a very-slow fixed aperture, an extremely thin focusing ring (if any at all), and a retractable lens element cover. Due to this compromise in design, body-cap lenses generally suffer from numerous image quality issues such as heavy vignetting and poor image sharpness.

Recently there has been a resurgence in this type of lens culminating in the one that seems extremely popular at this time, a cookie lens.

Cookie lens

It’s not hard to see why it is named so, it looks like a big Oreo cookie, it even looks as if it has the cream between the two biscuit pieces. These current ones are sold as being recycled from old disposable cameras. Original pancake lenses can cost many hundreds of pounds, however these ones are classed as disposable, and are priced at around £30 to £40GBP, being sold by a company called Retropia. But hold it! Don’t waste your money on that one, as they can be purchased for at least half that price from Ali Express of Temu, just make sure you shop around. By looking at the reviews £30 can still be a bit of a hefty outlay for what is basically a cheapo lens out of a disposable camera set in a cookie shaped piece of plastic.

These lenses have risen in popularity, as the new mirror less cameras have become more accessible. This lens allows these cameras to be used as a straight forward point and shoot camera, no focussing or metering. achieving that retro disposable camera look, but in much more modern equipment. It’s a fun item and for an outlay of around £13GBP, which is what I paid for mine, it’s not too big an outlay to do some experimenting with, and if it turns out to be a load of old bilge, then it’s no real loss. Reviews are mixed, but in general it seems people are having fun, and that’s what photography should be.

I’m waiting for mine to arrive, and when it does I shall post some photos below to see how I’ve got on with it. Oh, and I now have a suitable camera to use with this lens and that can be found here Sony A7II Mirrorless camera.

It’s such a simple thing. It turns a complex camera into a quite basic point and shoot disposable, lomography type of camera. Perfect for street photography and just everyday randomness, yep kind of like you’d now find on your mobile phone. However this is more fun and you actually have a camera into your hand, Perfect.

The lens is 32mm, and the CCD in the camera is full 35mm so there is a kind of small vignette around the edges of each shot, but that just adds to the basic rawness of the lens. it’s a bit of fun.

Above are a small selection of some of the scenes around home, taken quite randomly and all I have done in the post process is added some vintage presets. The light has been so poor lately that to be honest this already added to the vintage effect. If we see any sun I suspect the results would be very similar to the hazy 70s effect that the disposables always managed to achieve. Don’t expect too much from these lenses, they are just fun to experiment with, and that’s just what photography should be. Fun.

Thanks for passing by. Always appreciated.

No. It’s not just a mirror

There’s a little story that has developed here. Spring cleaning the house today and a mirror appears out of a cupboard and my wife has said,” You don’t need that, that can go.”

The mirror

At this statement I jumped up and unusually for me I gave the wife a firm reply of, “No” and told her it’s not going anywhere, there is a story behind that mirror and I then poured it out to her. Just as I am about to do so now to you all.

The mirror was a purchase from a Sunday magazine sometime in the mid 80s, nothing overly expensive but it always made me smile.

I’d just left home as my father’s abusive behaviour had taken a more violent turn. I was ashamed of myself for deserting my sister and mother, but I was just so fed up of being attacked both physically and mentally that I just snapped and left home.

I was about 18, I sofa surfed for a while, occasionally I sneaked into my workplace at night and slept there, I was all over the place and then found a spare room for rent in a property close by to where I’d originally lived. I had some stability in my life at last and was learning very quickly about moving on in life and the new responsibilities I’d now taken on. I then purchased this mirror, and would smile when I looked into it, it gave me some much needed fun and laughter in my life. Something that had been in very short supply for a while.

Then one night I broke when my sister appeared at the door, to tell me my father was attacking my mother, I grabbed the nearest thing to me that just happened to be a metal pole from an old photographic enlarger and I ran like the wind to their house. I charged up the stairs to their bedroom and stood over my father telling him just how I felt, and what a B***ard he was. I was about to bring that pole down on him when I realised he was in such a drunken stupor, he didn’t even know I was there, but beside him my Mum was reaching out to me weeping and calling my name. What she told me whilst we were embracing there is highly private and will always remain so, the crux of it was that she never wanted me to leave and begged me to come home.

I was back in that house before he’d even sobered up the following day. And that mirror I’d brought was on my bedroom wall where it stayed for a good few years.

I told my wife the story, and that the cheap worthless mirror was a subtle reminder of the time I started to turn my life around. I’d overcome fear of a tyrant and become the protector of the two most important people in my life at that time, my mum and younger sister. And I stayed with them until they both stepped away from this horrific existence.

A cheap mirror it maybe. But it still makes me smile. The wife has now said it must stay and be prominent in the house.

This picture was taken today, look, I’m smiling as I’m deciding where to put it up.

May it see many more smiles.

Garden solar lights

I purchased a pack of 5 of these cheap old garden lights from a local garden centre. I know if you buy cheap you pay twice but these did look quite reasonable. I know that most people only expect a season out of these lights however I try to look after mine, bringing them in during winter months when the garden isn’t being used and sunlight is non cooperative.

These were so full of promise, worked lovely for a few days and then two of them just didn’t work at all.

Broken garden solar lights

I took them apart and decided to test the batteries, both were showing 0.6v so i suspected the charge circuit was not working. When I put in a fully charged AA battery the lights came on but when exposed to light they remained on, so in a way I am right but it might be slightly more complicated. The battery isn’t charging, also the switch off is not occurring when exposed to light.

I’ve done a few tests using the multimeter, the solar panel is ok and giving a reasonable voltage under sunlight of 2.4v.

Solar panels working

The circuit board only consists of three components and two out of the three test ok. The issue seems to be with the YX8018 controller, the small four legged component in the pictures below.

What is a YX8018 controller?

YX8018 is a high-performance solar lawn
lamp boost control chip, which is suitable for a solar lawn lamp powered by a 1.2V rechargeable
battery in series.

The main functions include charging control, boost drive, optical control, etc.
The solar lawn lamp mainly uses the energy of
the solar cell to work. When the sunlight shines on the solar cell during the day, the light energy is transformed into electric energy and stored in the battery, and then the battery provides power for the LED (light emitting diode) of the lawn lamp at night.

It has the advantages of safety, energy saving,
convenience and environmental protection.It is
applicable to solar products powered by one 1.2V
rechargeable battery.

This appears to be the culprit after some basic tests have been carried out, there is about a 16% failure rate in these components so I don’t hold out a great deal of hope for the two that I’ve ordered. I shall eventually order a stack of them from China but for now I wanted some a bit quicker so I have ordered locally.

Two arrived….i now need three

Well, the two components I ordered have arrived today. But now I need three, as in the week another one has suffered the same issue. On top of that I have dropped one of the units and the solar panel has parted company. I’m now sourcing some liquid solder that may assist with getting this problem sorted. As is normal with me this little project has escalated due to my utter clumsiness. I must do better in the future. (Sounds just like one of my old school reports.)

In place ready to solder

I dismantled the two units I previously mentioned and followed pretty much the same process with each. Desolder, remove component, wick solder, put new component in place and then put a semi charged battery back in.

All soldered

I left the lights in the sun for a couple of hours and the charge has lifted from 0.8 to just over 1.1 volts so I’m happy that the charge circuit is now working.

The final test was to turn on and see what happens. Good news, nothing seen until I covered the solar panel and then the lights came on. Excellent, job done and more items saved from landfill. I must say I was really happy with my soldering on this job, it appears to be getting better.

Now working

I just need another component for that other one I broke in the week. However I won’t bother you with that one 😂
