Trade and Retail

.What advantages/disadvantages do CSC cameras have?

Compact system cameras – do not contain a mirror or an optical viewfinder, which makes them generally smaller than DSLRs. Instead of looking through the lens to compose your image via the viewfinder, mirrorless cameras let you preview your shot from a screen on the back of your camera.

However, DSLR cameras benefit from many years of development, refining the experience and comfort of using a traditional viewfinder. With advanced autofocus systems, these cameras have the ability to capture even the most difficult of subjects.

.What advantages/disadvantages do Rangefinder cameras have?

Advantages: Rangefinders are very very quiet because, unlike an SLR, there is no mirror to move out of the way when you depress the shutter. The “shutter” sound you hear on an SLR camera like the Nikon D700 or Canon 5D Mark II is actually the sound of the mirror inside the camera flipping up out of the way so that the lens can “see” the film or sensor at the back of the camera. Instant photo – basically zero shutter lag. Modern SLRs have some shutter lag but it’s very short,
– Rangefinders tend to look like old fashioned cameras and are very small relative to the size of even the smallest modern SLRs like the Nikon D40 or Nikon D5000 and so are less imposing. As the photographer, you are less noticeable and so can take photos that have more candor to them.

Disadvantages: – No autofocus
– limited
– Parallax problems – the viewfinder and the lens are not on the same axis
– Framing problems – you are not actually looking through the lens so the viewfinder has lines in it that tell you which part of what you are seeing through the viewfinder actually is inside the photo.
– limited number of manufacturers and limited advancement in the technology

.What are the differences between Trade and Retail?

The retail price is what the consumer pays to the retailer, shop owner or directly to you e.g. via your online shop. This is normally two and a half to three times the wholesale price, depending on the mark-up of the retailer.

The price at which goods are sold to shops by the people who produce them, rather than the price which the customer usually pays in the shop

.What advantages/disadvantages does equipment hire provide?


  • you don’t have to pay the full cost of the asset up front, so you don’t use up your cash or have to borrow money
  • you have access to a higher standard of equipment, which might be too expensive for you to buy outright
  • you pay for the asset over the fixed period of time that you use it, which helps you budget for the future
  • as interest rates on monthly rental costs are usually fixed, it is easier to forecast cashflow
  • you can spread the cost over a longer period of time and match payments to your income
  • the business can usually deduct the full cost of lease rentals from taxable income
  • if you have not bought the asset outright, you won’t have to worry about any overdraft or other loan taken out to finance the purchase being withdrawn at short notice, forcing early repayment
  • if you use an operating lease or contract hire, you may not have to worry about maintenance
  • the leasing company carries the risks if the equipment breaks down
  • the leasing company can usually get better deals on price than a small business could and will have superior product knowledge
  • on ‘long funding leases’ – finance leases over seven years and sometimes over five years; and some long operating leases – you can claim capital allowances on the cost of the assets
  • if you need to upgrade or replace the equipment, you can simply make a small adjustment to your regular payment rather than invest a lump sum upfront



  • you can’t claim capital allowances on the leased assets if the lease period is for less than five years (and in some cases less than seven years)
  • you may have to put down a deposit or make some payments in advance
  • it can work out to be more expensive than if you buy the assets outright
  • your business can be locked into inflexible medium or long-term agreements, which may be difficult to terminate
  • leasing agreements can be more complex to manage than buying outright and may add to your administration
  • your company normally has to be VAT-registered to take out a leasing agreement
  • when you lease an asset, you don’t own it, although you may be allowed to buy it at the end of the agreement

10.Trade and retail exists in the lab sector, are you aware of the  differences between ‘pro’ and ‘high street’ labs?

The big difference between a pro lab and a consumer lab is the drying method. A pro lab shall hang negatives and let air dry it while a consumer lab drys negatives with heat in a one-hour photo processing machine.
