Medium Format
Medium format refers to the size of your roll of film (or if you’re talking digital, it’s the size of the camera sensor). It really just means that you are shooting on a bigger piece of film than you do with a 35mm camera. The increased size of medium format film means a much larger negative. This will give you finer details and less grain.
Choosing your Right Medium Format Camera
Twin Lens Reflex (TLRS)
TLRs use two objective lens of the same focal length. The photographic objective lens is the one that is used to take the picture. The other lens, called the view lens, is connected to the viewfinder. Most TLRs are fixed focal length, and the more expensive models may incorporate a rudimentary room function. Most TLRs use a leaf shutter system, resulting in high speeds, quiet operation and low shutter vibration. There are also close-up, wide angle and telephoto adapters for TLRs.
Some popular TLRS cameras are: Yashica MAT-124G, Rolleiflex 2.8F, Minolta Autocord and Mamiya C330
Rangefinder
Rangefinder cameras are medium format cameras with a range finder. This negates the waistline, viewing that most TLRs carry. They are also much smaller than TLRs, and allow for easier point and shoot photographs. They tend to have limited focusing ranges, and do not have lenses larger than 180mm or 200mm. Rangefinders are quieter and easier to focus in dim light. They are mostly fixed lens models, but higher range models also provide for interchangeability.
Some popular rangefinder cameras are: Fujica G690, Mamiya 6/7, Bronica RF645, Norita 66 and Pentax 67

Extension Tubes
One limitation of macro photography when using a conventional lens is that there is a limit to how close you can focus due to the lens’s minimum focusing distance. Extension tubes for macro photography allow you to shift the focus zone of the lens you’re using so that the smallest of items are crystal clear and tack sharp. When doing macro photography, minimum focusing distance often becomes an issue because you can’t get in close enough to shoot your tiny subjects because your lens won’t focus that close.One solution is to get a set of extension tubes.
Close Up Lens Filter
Macro filters (also called close up filters) are filters that screw onto the front of a lens and act in a similar fashion to a magnifying glass. Placed between the subject and camera lens, the macro filter reduces the lens’ effective focal length. This in turn decreases the minimum focusing distance of the lens and allows for greater magnification. Macro filters are available in a range of +2 to +4 diopters. Wearers of glasses will recognise this term as it is also used to denote the amount of positive or negative magnification needed for eye corrections.
Reversing Rings
There are two main types of reversing rings available for macro photography. The first one is the regular reversing ring which attaches to your camera’s lens mount. And the second option is the coupler ring which connects to another lens instead of the camera itself.
If you want a simple set up, go with the traditional reversing ring. All you have to do is screw it on to the lens mount, and attach the lens backward. Since you reverse the glass, it ends up magnifying the image instead of making it smaller.
